Subject: [PATCH] rebase: extract code for writing basic state

Extrace the code for writing the state to rebase-apply/ or
rebase-merge/ when a rebase is initiated. This will make it easier to
later make both interactive and non-interactive rebase remember the
options used.

Note that non-interactive rebase stores the sha1 of the original head
in a file called orig-head, while interactive rebase stores it in a
file called head.
