[PATCH 06/11] git-fetch: Release objects used by a prior transport

["Shawn O. Pearce" <spearce@spearce.org>]

Some transports allocate objects in the internal object hashtable
during the fetch process (e.g. the HTTP commit walker and also the
native protocol).  These shouldn't be visible to another transport
call running in the same fetch process when we fetch the tags during
automated tag following.  By deallocating the object table (if it
has anything in it) we ensure the second transport execution will
be from a clean slate.
