Summary:
Remove the last associated types from BlobStore - this means that
BlobStore now has an associated trait object type.

Summary:
Don't use failure's bail!() and ensure!() macros.
Instead, failure_ext provides:
- bail_err!(err) - Converts its single parameter to the expected error and returns; ie `return Err(From::from(err));`
- bail_msg!(fmt, ...) - takes format string parameters and returns a `failure::err_msg()` error
- ensure_err!(), ensure_msg!() - corresponding changes
Also:
- remove all stray references to error-chain
- remove direct references to failure_derive (it's reexported via failure and failure_ext)
- replace uses of `Err(foo)?;` with `bail_err!()` (since `bail_err` unconditionally returns, but `Err(x)?` does not in principle, which can affect type inference)

Summary:
Convert scm/mononoke to use failure, and update common/rust crates it depends on as well.
What it looks like is a lot of deleted code...
General strategy:
- common/rust/failure_ext adds some things that are in git failure that aren't yet in crates.io (`bail!` and `ensure!`, `Result<T, Error>`)
- everything returns `Result<T, failure::Error>`
- crates with real error get an error type, with a derived Fail implementation
- replicate error-chain by defining an `enum ErrorKind` where the fields match the declared errors in the error! macro
- crates with dummy error-chain (no local errors) lose it
- `.chain_err()` -> `.context()` or `.with_context()`
So far the only place I've needed to extract an error is in a unit test.
Having a single unified error type has simplified a lot of things, and removed a lot of error type parameters, error conversion, etc, etc.

Summary:
Removes uses of deprecated Tokio API by doing the following:
1. Removing the ignore deprecation header
2. Including `futures_ext` in TARGETS
3. Porting all FutureBox uses to `futures_ext`
4. Porting `boxed()` to `boxify()`

Summary:
Similar to heads/bookmarks, share blobstore tests across
implementations.
The trait bounds got a bit tricky, but I think I managed to get the ones we
need and no more.

Summary:
Realized that we were missing a few crates from the Tokio cleanup because those crates
didn't have `#![deny(warnings)]`.
This also caused a bunch of files to be rustfmted, which is fine.

Summary:
Finally got an update working by removing the `mysql_async` crate.
Some notes:
* The `mysql_async` crate was responsible in this case: see https://github.com/rust-lang/cargo/issues/4066#issuecomment-328210204 for why.
* tokio/futures deprecated a bunch of stuff. I've filed a TODO for now.
* We finally pulled in error-chain 0.11, which has a bunch of nice improvements.
