[PATCH 00/13] remote helper improvements

[Sverre Rabbelier <srabbelier@gmail.com>]

I had a week and then some stray days here and there to do some more
work on git-remote-hg, the result of which is this series. It takes
the 'import' and 'export' commands out of their 'toy' stage, and gets
them ready for real usage. Although 'git-remote-testgit' is still the
only thing using them, 'git-remote-hg' is nearing completion, I hope
to send out an RFC for it Real Soon Now (TM).

Sverre Rabbelier (13):
      fast-import: add the 'done' command
      fast-export: support done feature

These two are very important to the rest of the series, most of the
clean up relies on the 'done' command to make 'import/export' part of
the remote helper protocol not suck.

      transport-helper: check status code of finish_command
      remote-curl: accept empty line as terminator

If nothing else is applied, these two should be taken out together
and applied separately.

      transport-helper: factor out push_update_refs_status
      transport-helper: update ref status after push with export

This is not very fleshed out yet, (the second patch in particular),
but without this 'git push' to a remote that uses the 'export'
capability will always say 'everything up-to-date'.

      transport-helper: use the new done feature to properly do imports
      transport-helper: export should disconnect too

These two make the 'import' and 'export' command re-entrant. That is,
now the remote helper infrastructure could issue other commands after
issuing an 'import' or 'export' command.

      transport-helper: change import semantics

This is another cleanup to the protocol, without this it is more or
less impossible to import multiple refs.

      transport-helper: Use capname for gitdir capability too

This is a candidate for for maint, the current implementation is just
plain wrong.

      transport-helper: implement marks location as capability

Another protocol cleanup.

      git-remote-testgit: only push for non-local repositories
      git-remote-testgit: fix error handling

Both of these are maint candidates, they are bugfixes.
