Summary:
When rendering commit messages, drive all the logic through field specification
classes instead of the hard-coded DifferentialCommitMessageData class. This
removes DifferentialCommitMessageData and support classes.
Note that this effectively reverts D546, and will cause a minor break for
Facebook (Task IDs will no longer render in commit messages generated by "arc
amend", and will not be editable via "arc diff --edit"). This can be resolved by
implementing the feature as a custom field. While I've been able to preserve the
task ID functionality elsewhere, I felt this implementation was too complex to
reasonably leave hooks for, and the break is pretty minor.
Test Plan:
- Made numerous calls to differential.getcommitmessage across many diffs in
various states, with and without 'edit' and with and without various field
overrides.
- General behavior seems correct (messages look accurate, and have the
expected information). Special fields like "Reviewed By" and "git-svn-id" seem
to work correctly.
- Edit behavior seems correct (edit mode shows all editable fields, hides
fields like "Reviewed By").
- Field overwrite behavior seems correct (overwritable fields show the correct
values when overwritten, ignore provided values otherwise).

Summary:
When we create or update a revision, we use a parsed commit message dictionary
to edit its fields. Drive consumption of the dictionary through custom fields
instead of hardcoding.
This requires adding some fields which don't really do anything right now to
cover fields which appear only in the commit message.
Test Plan: "arc diff"'d this revision against localhost, "arc diff"'d again to
update.
