Teach transport about the gitfile mechanism

The transport_get() function assumes that a regular file is a
bundle rather than a local git directory. Look inside the file
for the telltale "gitlink: " header to see if it is actually a
gitfile.  If so, do not try to process it as a bundle, but
treat it as a local repository instead.
