[PATCH 06/20] patman: Allow setting a git directory when sending

[Simon Glass]

Support specifying the git-directory when creating and sending patches.
This will allow better testing of this functionality, since we can use a
test directory.

For count_commits_to_branch() support an end commit while we are here.
