- New file. Adds logic to search for the git binary, as well
as determining the branch and revision, used in various
places.
Makefile:
- Remove searching for the svn{,lite} binary.
Makefile.ec2:
- Reduce duplicated code, removing searching for the svn{,lite}
binary, in addition to EC2_SVN{BRANCH,REV}.
- Rename EC2_SVN* with GIT* for consistency.
Makefile.mirrors:
- Remove the SRCBRANCH declaration, replaced with the exported
GITBRANCH variable.
- Update _SNAP_SUFFIX from SVNREVISION to GITREV, and remove
the leading 'r' from it, since it will break git hashes.
- Remove yet another instance of duplicated code to search for
the svn{,version}lite binary.
