The remote helper interface now supports the push capability,
which can be used to ask the implementation to push one or more
specs to the remote repository. For remote-curl we implement this
by calling the existing WebDAV based git-http-push executable.
Internally the helper interface uses the push_refs transport hook
so that the complexity of the refspec parsing and matching can be
reused between remote implementations. When possible however the
helper protocol uses source ref name rather than the source SHA-1,
thereby allowing the helper to access this name if it is useful.
>From Clemens Buchacher <drizzd@aon.at>:
update http tests according to remote-curl capabilities
o Pushing packed refs is now fixed.
o The transport helper fails if refs are already up-to-date. Add
a test for that.
o The transport helper will notice if refs are already
up-to-date. We therefore need to update server info in the
unpacked-refs test.
o The transport helper will purge deleted branches automatically.
o Use a variable ($ORIG_HEAD) instead of full SHA-1 name.

Some transports, like the native pack transport implemented by
fetch-pack, support useful features like depth or include tags.
These should be exposed if the underlying helper knows how to
use them.

Some network protocols (e.g. native git://) are able to fetch more
than one ref at a time and reduce the overall transfer cost by
combining the requests into a single exchange. Instead of feeding
each fetch request one at a time to the helper, feed all of them
at once so the helper can decide whether or not it should batch them.

We will need the walker, url and remote in other functions as the
code grows larger to support smart HTTP. Extract this out into a
set of globals we can easily reference once configured.

When we use -b <branch>, we may checkout something else than what the
remote's HEAD references, but we still used remote_head to supply the
new ref value to the post-checkout hook, which is wrong.
So instead of using remote_head to find the value to be passed to the
post-checkout hook, we have to use our_head_points_at, which is always
correctly setup, even if -b is not used.
This also fixes a segfault when "clone -b <branch>" is used with a
remote repo that doesn't have a valid HEAD, as in such a case
remote_head is NULL, but we still tried to access it.

All programs, in particular also the stand-alone programs (non-builtins)
must call git_extract_argv0_path(argv[0]) in order to help builds that
derive the installation prefix at runtime, such as the MinGW build.
Without this call, the program segfaults (or raises an assertion
failure).
