Make fetch a builtin

Thanks to Johannes Schindelin for review and fixes, and Julian
Phillips for the original C translation.

This changes a few small bits of behavior:

branch.<name>.merge is parsed as if it were the lhs of a fetch
refspec, and does not have to exactly match the actual lhs of a
refspec, so long as it is a valid abbreviation for the same ref.

branch.<name>.merge is no longer ignored if the remote is configured
with a branches/* file. Neither behavior is useful, because there can
only be one ref that gets fetched, but this is more consistant.

Also, fetch prints different information to standard out.
