Summary:
The first phase of pending changes is inspecting the filesystem for
changes. This diff adds that logic.

Summary:
The part of status that lists what files have changed is called
PendingChanges. This diff introduces the initial stub for PendingChanges. The
pending changes algorithm involves three parts:
1. Looking at files on the filesystem for changes.
2. Looking at files in the dirstate map for changes.
3. Looking at the content for any files that we were unsure of during steps 1
and 2.
This diff puts the basic state machine in place, and accepts the basic
information about the working copy (the root and what type of filesystem it is).
In the future we might have it detect what type of filesystem it is, but for now
this makes it easy.

Summary:
Previously, if the rust walker encountered any issues with individual
files it would stop and throw an exception or in some cases panic. To replace
the python walker we need to handle errors more gracefully, so let's add logic
for reporting which files had issues and what those issues were.
This also contains a minor one-line fix to prevent the walker from traversing
directories that contain a '.hg' directory.

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.

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