util: add util/maint/show_changes_by_file.py tool
The script diffs an upstream branch and a feature branch to find
all files which have been changed between the branches. It then
searches for all the corresponding changesets and binds them to
the files in the output.
The tool's output resembles the following:
/path/to/file/
filename
git-hash
git-hash
filename
git-hash
/path/to/file/
filename
git-hash
