Summary:
We used to carry patches for Tokio 0.2 to add support for disabling Tokio coop
(which was necessary to make Mononoke work with it), but this was upstreamed
in Tokio 1.x (as a different implementation), so that's no longer needed. Nobody
else besides Mononoke was using this.
For Hyper we used to carry a patch with a bugfix. This was also fixed in Tokio
1.x-compatible versions of Hyper. There are still users of hyper-02 in fbcode.
However, this is only used for servers and only when accepting websocket
connections, and those users are just using Hyper as a HTTP client.

Summary:
NOTE: there is one final pre-requisite here, which is that we should default all Mononoke binaries to `--use-mysql-client` because the other SQL client implementations will break once this lands. That said, this is probably the right time to start reviewing.
There's a lot going on here, but Tokio updates being what they are, it has to happen as just one diff (though I did try to minimize churn by modernizing a bunch of stuff in earlier diffs).
Here's a detailed list of what is going on:
- I had to add a number `cargo_toml_dir` for binaries in `eden/mononoke/TARGETS`, because we have to use 2 versions of Bytes concurrently at this time, and the two cannot co-exist in the same Cargo workspace.
- Lots of little Tokio changes:
- Stream abstractions moving to `tokio-stream`
- `tokio::time::delay_for` became `tokio::time::sleep`
- `tokio::sync:⌚:Sender::send` became `tokio::sync:⌚:Sender::broadcast`
- `tokio::sync::Semaphore::acquire` returns a `Result` now.
- `tokio::runtime::Runtime::block_on` no longer takes a `&mut self` (just a `&self`).
- `Notify` grew a few more methods with different semantics. We only use this in tests, I used what seemed logical given the use case.
- Runtime builders have changed quite a bit:
- My `no_coop` patch is gone in Tokio 1.x, but it has a new `tokio::task::unconstrained` wrapper (also from me), which I included on `MononokeApi::new`.
- Tokio now detects your logical CPUs, not physical CPUs, so we no longer need to use `num_cpus::get()` to figure it out.
- Tokio 1.x now uses Bytes 1.x:
- At the edges (i.e. streams returned to Hyper or emitted by RepoClient), we need to return Bytes 1.x. However, internally we still use Bytes 0.5 in some places (notably: Filestore).
- In LFS, this means we make a copy. We used to do that a while ago anyway (in the other direction) and it was never a meaningful CPU cost, so I think this is fine.
- In Mononoke Server it doesn't really matter because that still generates ... Bytes 0.1 anyway so there was a copy before from 0.1 to 0.5 and it's from 0.1 to 1.x.
- In the very few places where we read stuff using Tokio from the outside world (historical import tools for LFS), we copy.
- tokio-tls changed a lot, they removed all the convenience methods around connecting. This resulted in updates to:
- How we listen in Mononoke Server & LFS
- How we connect in hgcli.
- Note: all this stuff has test coverage.
- The child process API changed a little bit. We used to have a ChildWrapper around the hg sync job to make a Tokio 0.2.x child look more like a Tokio 1.x Child, so now we can just remove this.
- Hyper changed their Websocket upgrade mechanism (you now need the whole `Request` to upgrade, whereas before that you needed just the `Body`, so I changed up our code a little bit in Mononoke's HTTP acceptor to defer splitting up the `Request` into parts until after we know whether we plan to upgrade it.
- I removed the MySQL tests that didn't use mysql client, because we're leaving that behind and don't intend to support it on Tokio 1.x.

Summary:
This diffs add a layer of indirection between fbinit and tokio, thus allowing
us to use fbinit with tokio 0.2 or tokio 1.x.
The way this works is that you specify the Tokio you want by adding it as an
extra dependency alongside `fbinit` in your `TARGETS` (before this, you had to
always include `tokio-02`).
If you use `fbinit-tokio`, then `#[fbinit::main]` and `#[fbinit::test]` get you
a Tokio 1.x runtime, whereas if you use `fbinit-tokio-02`, you get a Tokio 0.2
runtime.
This diff is big, because it needs to change all the TARGETS that reference
this in the same diff that introduces the mechanism. I also didn't produce it
by hand.
Instead, I scripted the transformation using this script: P242773846
I then ran it using:
```
{ hg grep -l "fbinit::test"; hg grep -l "fbinit::main" } | \
sort | \
uniq | \
xargs ~/codemod/codemod.py \
&& yes | arc lint \
&& common/rust/cargo_from_buck/bin/autocargo
```
Finally, I grabbed the files returned by `hg grep`, then fed them to:
```
arc lint-rust --paths-from ~/files2 --apply-patches --take RUSTFIXDEPS
```
(I had to modify the file list a bit: notably I removed stuff from scripts/ because
some of that causes Buck to crash when running lint-rust, and I also had to add
fbcode/ as a prefix everywhere).

Summary:
This diff rollouts V2 of autocargo in an atomic way so there are quite a few things done here.
Arc lint support:
V1 used to be part of the default fbsource `arc lint` engine, but since V2 calls buck it must live in a separate lint engine. So this diff:
- Adds running `autocargo` as part of `arc lint-rust`
Mergedriver update:
- Mergedriver used in resolving conflicts on commits is now pointing to V2
- It handles files in `public_autocargo/` directories in addition to the ones containig generation preamble
Including regeneration results of running `common/rust/cargo_from_buck/bin/autocargo`. All the differences are accounted for:
- Some sections and attributes are removed as they can be autodiscovered by Cargo (like `lib.path = "src/lib.rs"` or empty [lib] section)
- "readme" attribute is properly defined as relative to Cargo.toml location rather than as hardcoded string
- "unittest = false" on a Buck rule propagates as "test = false; doctest = false" to Cargo
- "rusqlite" is not special-cased anymore, so the "budled" feature will have to be enabled using custom configuration if required by the project (for rust-shed in order to not break windows builds a default feature section was added)
- Files generated from thrift_library rules that do not support "rust" language are removed
- Custom .bzl rules that create rust artifacts (like `rust_python_extension`) are no longer ignored
Others:
- Changed `bin/cargo-autocargo` to be a wrapper for calling V2 via `cargo autocargo`
- Updated following files to use V2:
- `common/rust/tools/reindeer/version-bump`
- `remote_execution/rust/setup.sh`
- Removed few files from V1 that would otherwise interfere with V2 automatic regeneration/linting/testing

For dependencies V2 puts "version" as the first attribute of dependency or just after "package" if present.
Workspace section is after patch section in V2 and since V2 autoformats patch section then the third-party/rust/Cargo.toml manual entries had to be formatted manually since V1 takes it as it is.
The thrift files are to have "generated by autocargo" and not only "generated" on their first line. This diff also removes some previously generated thrift files that have been incorrectly left when the corresponding Cargo.toml was removed.

Summary:
The earlier diffs in this stack have removed all our dependencies on the Tokio
0.1 runtime environment (so, basically, `tokio-executor` and `tokio-timer`), so
we don't need this anymore.
We do still have some deps on `tokio-io`, but this is just traits + helpers,
so this doesn't actually prevent us from removing the 0.1 runtime!
Note that we still have a few transitive dependencies on Tokio 0.1:
- async-unit uses tokio-compat
- hg depends on tokio-compat too, and we depend on it in tests
This isn't the end of the world though, we can live with that :)

Summary:
The changes (and fixes) needed were:
- Ignore rules that are not rust_library or thrift_library (previously only ignore rust_bindgen_library, so that binary and test dependencies were incorrectly added to Cargo.toml)
- Thrift package name to match escaping logic of `tools/build_defs/fbcode_macros/build_defs/lib/thrift/rust.bzl`
- Rearrange some attributes, like features, authors, edition etc.
- Authors to use " instead of '
- Features to be sorted
- Sort all dependencies as one instead of grouping third party and fbcode dependencies together
- Manually format certain entries from third-party/rust/Cargo.toml, since V2 formats third party dependency entries and V1 just takes them as is.

Also the "include" field is apparently obsolete as it is used for cargo-publish (see https://doc.rust-lang.org/cargo/reference/manifest.html#the-exclude-and-include-fields). From what I know this might be often wrong, especially if someone tries to publish a package from fbcode, then the private facebook folders might be shipped. Lets just not set it and in the new system one will be able to set it explicitly via autocargo parameter on a rule.

Summary:
Lots of generated code in this diff. Only code change was in
`common/rust/cargo_from_buck/lib/cargo_generator.py`.
Path/git-only dependencies (ie `mydep = { path = "../foo/bar" }`) are not
publishable to crates.io. However, we are allowed to specify both a path/git
_and_ a version. When building locally, the path/git is chosen. When publishing,
the version on crates.io is chosen.
See https://doc.rust-lang.org/cargo/reference/specifying-dependencies.html#multiple-locations .
Note that I understand that not all autocargo projects are published on crates.io (yet).
The point of this diff is to allow projects to slowly start getting uploaded.
The end goal is autocargo generated `Cargo.toml`s that can be `cargo publish`ed
without further modification.

Summary:
When we tried to update to Tokio 0.2.14, we hit lots of hangs. Those were due
to incompatibilities between Tokio 0.2.14 and Futures 1.29. We fixed some of
the bugs (and others had been fixed and were pending a release), and Futures
1.30 have now been released, which unblocks our update.
This diff updates Tokio accordingly (the previous diff in the stack fixes an
incompatibility).
The underlying motivation here is to ease the transition to Tokio 1.0.
Ultimately we'll be pulling in those changes one or way or another, so let's
get started on this incremental first step.

Summary:
This trait is no longer used all that much outsides of a handful of tests, the
walker, and an admin subcommand, as it has been replaced by the `Manifest`
trait, which works over all kinds of Manifests, and has stronger typing (its
sub-entries always have a path, and they are wrapped in an enum that knows if
they're leaves or trees).
This left a bunch of old legacy code here or there, which is worth removing
to make sure we don't introduce any new callsites to this. Another motivation
is that this legacy code is often not very compatible with new code, and has
historically made it a bit tricky (everything owns a blobstore in this code,
which is pretty awkward and not at all how we do things nowadays).
There is, I think, a bit more potential here since we could also perhaps try to
remove the `HgBlobEntry` struct, but that has a callsites still, so I'm not
doing this here.

Summary:
Eventually, we want everything to be `async`/`await`; as a stepping stone in that direction, switch some of the blobstore interfaces to new-style `BoxFuture` with a `'static` lifetime.
This does not enable any fixes at this point, but does mean that `.compat()` moves to the places that need old-style futures instead of new. It also means that the work needed to make the transition fully complete is changed from a full conversion to new futures, to simply changing the lifetimes involved and fixing the resulting compile failures.

Summary:
This allows code that is being exercised under async_unit to call into code
that expects a Tokio 0.2 environment (e.g. 0.2 timers).
Unfortunately, this requires turning off LSAN for the async_unit tests, since
it looks like LSAN and Tokio 0.2 don't work very well together, resulting in
LSAN reporting leaked memory for some TLS structures that were initialized by
tokio-preview (regardless of whether the Runtime is being dropped):
https://fb.workplace.com/groups/rust.language/permalink/3249964938385432/
Considering async_unit is effectively only used in Mononoke, and Mononoke
already turns off LSAN in tests for precisely this reason ... it's probably
reasonable to do the same here.
The main body of changes here is also about updating the majority of our
changes to stop calling wait(), and use this new async unit everywhere. This is
effectively a pretty big batch conversion of all of our tests to use async fns
instead of the former approaches. I've also updated a substantial number of
utility functions to be async fns.
A few notable changes here:
- Some pushrebase tests were pretty flaky — the race they look for isn't
deterministic. I added some actual waiting (using pushrebase hooks) to make
it more deterministic. This is kinda copy pasted from the globalrev hook
(where I had introduced this first), but this will do for now.
- The multiplexblob tests don't work at all with new futures, because they call
`poll()` all over the place. I've updated them to new futures, which required
a bit of reworking.
- I took out a couple tests in async unit that were broken anyway.
