7851b1e60f remote-fd/ext: finishing touches after code review
When compiling with pthread support, transport-helper.c needs to include
necessary header files.  Also fix a few error messages in remote-ext and
remote-fd programs, and a potential buffer underrun in remote-fd.

In the documentation, clarify how %G and %V are used; the old description
looked as if they take repository/vhost parameters, which was wrong.

Also fix AsciiDoc markup for the page title of remote-fd/remote-ext manpages,
and tweak the way how section headers are shown.

88f3b2b0a2 remote-helpers: allow requesing the path to the .git directory
The 'gitdir' capability is reported by the remote helper if it
requires the location of the .git directory. The location of the .git
directory can then be used by the helper to store status files even
when the current directory is not a git repository (such as is the
case when cloning).

The location of the .git dir is specified as an absolute path.

d01b3c02e8 transport->progress: use flag authoritatively
Set transport->progress in transport.c::transport_set_verbosity() after
checking for the appropriate conditions (eg. --progress, isatty(2)),
and thereafter use it without having to check again.

The rules used are as follows (processing aborts when a rule is
satisfied):

  1. Report progress, if force_progress is 1 (ie. --progress).
  2. Don't report progress, if verbosity < 0 (ie. -q/--quiet).
  3. Report progress if isatty(2) is 1.

This changes progress reporting behaviour such that if both --progress
and --quiet are specified, progress is reported.

In two areas, the logic to determine whether to *not* show progress is
changed to simply use the negation of transport->progress. This changes
behaviour in some ways (see previous paragraph for details).

08d63a422b transport-helper.c::push_refs(): ignore helper-reported status if ref is not to be pushed
If the status of a ref is REF_STATUS_NONE, the remote helper will not
be told to push the ref (via a 'push' command).

However, the remote helper may still act on these refs.

If the helper does act on the ref, and prints a status for it, ignore
the report (ie. don't overwrite the status of the ref with it, nor the
message in the remote_status member) if the reported status is 'no
match'.

This allows the user to be alerted to more "interesting" ref statuses,
like REF_STATUS_NONFASTFORWARD.

20e8b465a5 refactor ref status logic for pushing
Move the logic that detects up-to-date and non-fast-forward refs to a
new function in remote.[ch], set_ref_status_for_push().

Make transport_push() invoke set_ref_status_for_push() before invoking
the push_refs() implementation. (As a side-effect, the push_refs()
implementation in transport-helper.c now knows of non-fast-forward
pushes.)

Removed logic for detecting up-to-date refs from the push_refs()
implementation in transport-helper.c, as transport_push() has already
done so for it.

Make cmd_send_pack() invoke set_ref_status_for_push() before invoking
send_pack(), as transport_push() can't do it for send_pack() here.

Mark the test on the return status of non-fast-forward push to fail.
Git now exits with success, as transport.c::transport_push() does not
check for refs with status REF_STATUS_REJECT_NONFASTFORWARD nor does it
indicate rejected pushes with its return value.

Mark the test for ref status to succeed. As mentioned earlier, refs
might be marked as non-fast-forwards, triggering the push status
printing mechanism in transport.c.

ae4efe1957 Move WebDAV HTTP push under remote-curl
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.
