Summary:
On Windows, some Mercurial commands may create files in `.hg` directory even if
EdenFS is not running. As a result, the command itself will fail while the file
still left in the directory. Users typically will then start EdenFS and repeat
the same command.
However, due to the current design of EdenFS, it will not be able to recognize
these files created when it is stopped and return errors for any attempts to
write/remove the file, generate another error. Users then need to stop EdenFS
and manually remove the file in `.hg` directory to recover the repository. This
creates a very bad user experience.
The correct way to fix this is to teach EdenFS to track the modifications
happened when it is not running, however this will take a few weeks to get
there. For a temporary measurement, we teach Mercurial to abort when EdenFS
isn't running to avoid trickier recoveries.

Summary:
Generated by formatting with rustfmt 2.0.0-rc.2 and then a second time with fbsource's current rustfmt (1.4.14).
This results in formatting for which rustfmt 1.4 is idempotent but is closer to the style of rustfmt 2.0, reducing the amount of code that will need to change atomically in that upgrade.

*Why now?* **:** The 1.x branch is no longer being developed and fixes like https://github.com/rust-lang/rustfmt/issues/4159 (which we need in fbcode) only land to the 2.0 branch.

This makes `make hg3` work. It requires cleaning up the `build` directory when

Summary:
The memcache code assumes it's initialized, let's actually do it.
The test change is required due to fbinit installing its own SIGTERM handler
that shows a backtrace. Installing our own SIGTERM handler makes it closer to
what Mercurial does already.

Summary:
The hgpython interpreter was used to run Python scripts in tests that might
rely on Mercurial modules.
The previous hgpython implementation is Python PAR based, which does not have
access to native Rust modules like bindings. Change it to use the native
"hg debugpython" implementation that is more compatible.

Summary:
This diff replaces eden's dependencies on failure::Error with anyhow::Error.
Failure's error type requires all errors to have an implementation of failure's own failure::Fail trait in order for cause chains and backtraces to work. The necessary methods for this functionality have made their way into the standard library error trait, so modern error libraries build directly on std::error::Error rather than something like failure::Fail. Once we are no longer tied to failure 0.1's Fail trait, different parts of the codebase will be free to use any std::error::Error-based libraries they like while still working nicely together.
