[PATCH resend 0/3] transport: catch non-fast-forwards

[Tay Ray Chuan <rctay89@gmail.com>]

This patch series applies on top of 'next', and deals with alerting
the user to non-fast-forward pushes when using helpers (smart).

Previously, git silently exited. This situation involves the curl
helper and the smart protocol. The fast-forward push is only detected
when curl executes the rpc client (git-send-pack). Now, we detect it
before telling the helper to push.

The first patch refactors ref status logic out of builtin-send-pack.c.

The second patch lets git know of non-fast-forwards before actually
telling the helper to push anything.

The third patch changes the return code when ref status indicate an
error (determined by push_had_errors()), so that the caller of
transport_push() is alerted.

PS. There are at least 2 bug fixes related to this series. If you
usually do so from repo.or.cz, please fetch from git.kernel.org; the
former is 2 days old.
