Sped up unused.

Browse source 
Added Git.ByteString which replaces Git IO methods with ones using lazy
ByteStrings. This can be more efficient when large quantities of data are
being read from git.

In Git.LsTree, parse git ls-tree output more efficiently, thanks
to ByteString. This benchmarks 25% faster, in a benchmark that includes
(probably predominately) the run time for git ls-tree itself.

In real world numbers, this makes git annex unused 2 seconds faster for
each branch it needs to check, in my usual large repo.
