Summary:
Basically every single Mononoke binary starts with the same preamble:
- Init mononoke
- Init caching
- Init logging
- Init tunables
Some of them forget to do it, some don't, etc. This is a mess.
To make things messier, our initialization consists of a bunch of lazy statics
interacting with each other (init logging & init configerator are kinda
intertwined due to the fact that configerator wants a logger but dynamic
observability wants a logger), and methods you must only call once.
This diff attempts to clean this up by moving all this initialization into the
construction of MononokeMatches. I didn't change all the accessor methods
(though I did update those that would otherwise return things instantiated at
startup).
I'm planning to do a bit more on top of this, as my actual goal here is to make
it easier to thread arguments from MononokeMatches to RepoFactory, and to do so
I'd like to just pass my MononokeEnvironment as an input to RepoFactory.

Summary:
Bounded traversal's internal book-keeping moves the futures returned from fold and unfold callbacks around while they are being queued to be scheduled. If these futures are large, then this can result in a significant portion of bounded traversal's CPU time being spent on `memcpy`ing these futures around.
This can be prevented by always boxing the futures that are returned to bounded traversal. Make this a requirement by changing the type from `impl Future<...>` to `BoxFuture<...>`.

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:
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.

Summary:
Autocargo V2 will use a more structured format for autocargo field
with the help of `cargo_toml` crate it will be easy to deserialize and handle
it.
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.
