git-svn: extract reusable code into utility functions
Extacted canonicalize_path() in the main package. Created new Git::SVN::Util package with an md5sum() function. A new package was created so that Digest::MD5 did not have to be loaded in the main package. Replaced code in the SVN::Git::Editor and SVN::Git::Fetcher packages with calls to md5sum(). Extracted the format_svn_date(), parse_git_date() and set_local_timezone() functions within the Git::SVN::Log package. Signed-off-by: David D. Kilzer <ddkilzer@kilzer.net> Acked-by: Eric Wong <normalperson@yhbt.net>
