This series does a lot of work around making the default rebase backend
configurable, and switching the default from the am backend to the
merge/interactive one.

See the cover letter for v1[*] for a more detailed motivation for the
series, the type of changes being made, and areas I'd like to reviewers to
focus on.

Changes since v1:

 * Made some cleanups to the empty type parsing, as suggested by Junio
   (Patch 1)
 * Changed the shell prompt for all rebases to just be "REBASE", as
   suggested by SZEDER (Patch 11)
 * Correctly check that work was done (by checking that reflog grew, patch
   6); flagged by Denton
