Make cvsexportcommit work with filenames with spaces and non-ascii characters.

This patch uses git-apply to do the patching which simplifies the code a lot
and also uses one pass to git-diff. git-apply gives information on added,
removed files as well as which files are binary.

Removed the test for checking for matching binary files when deleting them
since git-apply happily deletes the file. This is matter of taste since we
allow some fuzz for text patches also.

Error handling was cleaned up, but not much tested.
