Summary:
Asyncmemo has two issues for our use:
1. Separate memory pool from cachelib caches.
2. Future fusion means that a `get` that should succeed will fail because there
was an earlier get still in progress.
The second is good for memoization, where the worst case from a failed get is
extra CPU work, but not so good for caching. Replace uses of Asyncmemo for
caches with a cachelib based cache

Summary:
This is a series of patches which adds Cargo.toml files to all the crates and tries to build them. There is individual patch for each crate which tells whether that crate build successfully right now using cargo or not, and if not, reason behind that.
Following are the reasons why the crates don't build:
* failure_ext and netstring crates which are internal
* error related to tokio_io, there might be an patched version of tokio_io internally
* actix-web depends on httparse which uses nightly features
All the build is done using rustc version `rustc 1.27.0-dev`.

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.
