Summary:
Provide a way to repair the MetaLog. It's not just repairing 2 indexedlog
structures, but also checking the relationships between them.

Summary:
The previously behavior silently uses the empty Root upon "id not found" cases,
which hides data corruption issues captured by the next changes.

Summary:
This helps test if there are uncommitted changes. It can help detecting
programming errors. For example, is metalog changed before starting a
transaction?

Summary:
The current `commit` code path errors out without telling much about what
conflicts are. Improve it by showing what are actually conflicting, and allows
users to replace the resolver function to do customized merges.

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.

In preparation for merging fb-mercurial sources to the Eden repository,
move everything from the top-level directory into an `eden/scm`
subdirectory.
