[PATCH 2/4] remote.c: introduce a way to have different remotes for fetch/ push

[Ramkumar Ramachandra <artagnon@gmail.com>]

Currently, do_push() in push.c calls remote_get(), which gets the
configured remote for fetching and pushing.  Replace this call with a
call to pushremote_get() instead, a new function that will return the
remote configured specifically for pushing.  This function tries to
work with the string pushremote_name, before falling back to the
codepath of remote_get().  This patch has no visible impact, but
serves to enable future patches to introduce configuration variables
to set this variable.
