Summary:
Types that are defined by the manifest core crate should have test utilities
defined in the same crate.
This is motivated by various warning in the buck build.

`hgid` can be easily derived from the link member variable. Using link is
preferable because link is the owner of the data. It makes the logic more
specific, less bug prone to use the true source of the data.

Summary:
Querying all the files in a Manifest is core functionality that every Manifest
implementation should implement. The main question is how do we describe that.
We want to return an interator over the files of the manifest. The problem is
that the manifest is a trait and functions on traits can't return traits.
The solution is to Box the results. Not pretty but allows us to move the code
forward.

Summary:
When changing a file to a folder in a commit this function would try to query
the storage using the path and the id of the file. Storage would not have
such an entry and would cause the operation to fail.
Fixing the issue by filtering out ids of files in the section for known
manifests. Filtering already occurs in the section for transmitted manifest.

Summary:
The Mercurial code has the bad habbit of inserting files in what can
appear impossible locations. Sometimes files with directory names and
sometimes directories in file locations. This happens because the initial
code would do additions before deletions on Manifest implementations that
were rudimentary. As soon as we introduce validation various code paths
surface.
I tried to fix the codepaths that modify manifests but it's a losing game.
I fixed the issue that appeared in tests and a couple of issues people
reported but more situations crop up.
This is giving up on the python code.

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:
This diff is preparation for migrating off of failure::Fail / failure::Error for errors in favor of errors that implement std::error::Error. The Fallible terminology is unique to failure and in non-failure code we should be using Result<T>. To minimize the size of the eventual diff that removes failure, this codemod replaces all use of Fallible with Result by:
- In modules that do not use Result<T, E>, we import `failure::Fallible as Result`;
- In modules that use a mix of Result<T, E> and Fallible<T> (only 5) we define `type Result<T, E = failure::Error> = std::result::Result<T, E>` to allow both Result<T> and Result<T, E> to work simultaneously.
