Summary:
This diff updates all license headers to use the new text and style.
Also, a few internal files were missing the header, but now they have it.
`fbcode/common/rust/netstring/` had the internal header, but now it has
GPLV2PLUS - since that goes to Mononoke's Github too.

Summary:
Start moving mercurial related stuff to `mercurial` directory:
- rename `mercurial` to `mercurial_revlog` and moved to `/mercurial/revlog`
- move `mercurial_types` to `/mercurial/types`
- move `mercurial_bundles` to `/mercurial/bundels`

Summary: The Copy trait means that something is so cheap to copy that you don't even need to explicitly do `.clone()` on it. As it doesn't make much sense to pass &i64 it also doesn't make much sense to pass &<Something that is Copy>, so I have removed all the occurences of passing one of ouf hashes that are Copy.

Summary: This commits change `HgBlob` from an enum into a struct that only contains one Bytes field, completely removes `HgBlobHash` and changes the methods of `HgBlob` from returning `Option`s into directly returning results.

Summary:
RevlogRepo exposes a ton of methods that are almost equvalent to taking Revlog directly and ignoring the RevloRepo abstraction above it.
This diff cleans this up a bit, there are still some methods that the "old" blobimport uses, but the "new" one shouldn't need to do that.

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.
