Summary: D22381744 updated the version of `futures` in third-party/rust to 0.3.5, but did not regenerate the autocargo-managed Cargo.toml files in the repo. Although this is a semver-compatible change (and therefore should not break anything), it means that affected projects would see changes to all of their Cargo.toml files the next time they ran `cargo autocargo`.

Summary:
Eventually, we want everything to be `async`/`await`; as a stepping stone in that direction, switch the remaining lobstore traits to new-style futures.
This just pushes the `.compat()` out to old-style futures, but it makes the move to non-'static lifetimes easier, as all the compile errors will relate to lifetime issues.

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:
All the changes we need are now in stable, so use the stable crates.io version.
I also had to do coordinated updates of git2 and rustsec to make sure they're
all using the same version of libgit2-sys. This had a couple of little API changes which affected our code:
- mononoke gitimport (krallin)
- linttool (zertosh) (BTW the old code had some very dubious lifetime stuff - a signature of the form `fn foo<'a>(&self) -> Thing<'a>` never makes any sense - output lifetimes should always be derived from the params)
Similarly, toml-rs needed to be updated because there's now a hard dependency on 0.5.6.

Summary:
The original gitimport wasn't really designed for concurrency, since it did
commits one by one. With this update, we can now derive Bonsais from multiple
commits in parallel, and use multiple threads to communicate with the Git
repository (which is actually somewhat expensive when that's all we do).
We also store Bonsais iteratively. There is a bit of extra work that could be
done also here by saving Bonsais asynchronously to the Blobstore, and inserting
a single batch in Changesets once we're finished.

This diff turns off the support_old_nightly feature of async-trait (https://github.com/dtolnay/async-trait/blob/0.1.24/Cargo.toml#L28-L32) everywhere in fbcode. I am getting ready to remove the feature upstream. It was an alternative implementation of async-trait that produces worse error messages but supports some older toolchains dating back to before stabilization of async/await that the default implementation does not support.
This diff includes updating async-trait from 0.1.24 to 0.1.29 to pull in fixes for some patterns that used to work in the support_old_nightly implementation but not the default implementation.

Summary:
This is a small refactoring that does two things:
1) Move StoreLoadable into the Blobstore crate. This might be a bit
controversial since StoreLoadable doesn't have anything to do with blobstore.
But I put it there for a few reasons:
* In the next diffs I want to use StoreLoadable in mononoke_types. However I
can't create dependency from `mononoke_types` crate to `manifest` crate because
`manifest` depends on `mononoke_types`
* `manifest` crate doesn't look like a good place for this struct either
* I didn't find a better place for it - don't want to put it in crates like
`common`, and it creating a separate crate just for this trait looks like an
overkill.
2) Changes error type to LoadableError to match Loadable trait. This add one
FIXME for git tree which doesn't differentiate between these errors.

Summary:
The Bytes 0.5 update left us in a somewhat undesirable position where every
access to our blobstore incurs an extra copy whenever we fetch data out of our
cache (by turning it from Bytes 0.5 into Bytes 0.4) — we also have quite a few
place where we convert in one direction then immediately into the other.
Internally, we can start using Bytes 0.5 now. For example, this is useful when
pulling data out of our blobstore and deserializing as Thrift (or conversely,
when serializing and putting it into our blobstore).
However, when we interface with Tokio (i.e. decoders & encoders), we still have
to use Bytes 0.4. So, when needed, we convert our Bytes 0.5 to 0.4 there.
The tradeoff idea is that we deal with more bytes internally than we end up
sending to clients, so doing the Bytes conversion closer to the point of
sending data to clients means less copies.
We can also start removing those once we migrate to Tokio 0.2 (and newer
versions of Hyper for HTTP services).
Changes that were required:
- You can't extend new bytes (because that implicitly copies). You need to use
BytesMut instead, which I did where that was necessary (I also added calls in
the Filestore to do that efficiently).
- You can't create bytes from a `&'a [u8]`, unless `'a` is `'static`. You need
to use `copy_from_slice` instead.
- `slice_to` and `slice_from` have been replaced by a `slice()` function that
takes ranges.

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.
