rebase: implement --merge via the interactive machinery
As part of an ongoing effort to make rebase have more uniform behavior,
modify the merge backend to behave like the interactive one, by
re-implementing it on top of the latter.
Interactive rebases are implemented in terms of cherry-pick rather than
the merge-recursive builtin, but cherry-pick also calls into the
recursive merge machinery by default and can accept special merge
strategies and/or special strategy options. As such, there really is
not any need for having both git-rebase--merge and
git-rebase--interactive anymore. Delete git-rebase--merge.sh and
instead implement it in builtin/rebase.c.
This results in a few deliberate but small user-visible changes:
* The progress output is modified (see t3406 and t3420 for examples)
* A few known test failures are now fixed (see t3421)
* bash-prompt during a rebase --merge is now REBASE-i instead of
REBASE-m. Reason: The prompt is a reflection of the backend in use;
this allows users to report an issue to the git mailing list with
the appropriate backend information, and allows advanced users to
know where to search for relevant control files. (see t9903)
testcase modification notes:
t3406: --interactive and --merge had slightly different progress output
while running; adjust a test to match the new expectation
t3420: these test precise output while running, but rebase--am,
rebase--merge, and rebase--interactive all were built on very
different commands (am, merge-recursive, cherry-pick), so the
tests expected different output for each type. Now we expect
--merge and --interactive to have the same output.
t3421: --interactive fixes some bugs in --merge! Wahoo!
t9903: --merge uses the interactive backend so the prompt expected is
now REBASE-i.

git-rebase, sequencer: extend --quiet option for the interactive machinery
While 'quiet' and 'interactive' may sound like antonyms, the interactive
machinery actually has logic that implements several
interactive_rebase=implied cases (--exec, --keep-empty, --rebase-merges)
which won't pop up an editor. The rewrite of interactive rebase in C
added a quiet option, though it only turns stats off. Since we want to
make the interactive machinery also take over for git-rebase--merge, it
should fully implement the --quiet option.
git-rebase--interactive was already somewhat quieter than
git-rebase--merge and git-rebase--am, possibly because cherry-pick has
just traditionally been quieter. As such, we only drop a few
informational messages -- "Rebasing (n/m)" and "Successfully rebased..."
Also, for simplicity, remove the differences in how quiet and verbose
options were recorded. Having one be signalled by the presence of a
"verbose" file in the state_dir, while the other was signalled by the
contents of a "quiet" file was just weirdly inconsistent. (This
inconsistency pre-dated the rewrite into C.) Make them consistent by
having them both key off the presence of the file.

assert NOARG/NONEG behavior of parse-options callbacks
When we define a parse-options callback, the flags we put in the option
struct must match what the callback expects. For example, a callback
which does not handle the "unset" parameter should only be used with
PARSE_OPT_NONEG. But since the callback and the option struct are not
defined next to each other, it's easy to get this wrong (as earlier
patches in this series show).
Fortunately, the compiler can help us here: compiling with
-Wunused-parameters can show us which callbacks ignore their "unset"
parameters (and likewise, ones that ignore "arg" expect to be triggered
with PARSE_OPT_NOARG).
But after we've inspected a callback and determined that all of its
callers use the right flags, what do we do next? We'd like to silence
the compiler warning, but do so in a way that will catch any wrong calls
in the future.
We can do that by actually checking those variables and asserting that
they match our expectations. Because this is such a common pattern,
we'll introduce some helper macros. The resulting messages aren't
as descriptive as we could make them, but the file/line information from
BUG() is enough to identify the problem (and anyway, the point is that
these should never be seen).
Each of the annotated callbacks in this patch triggers
-Wunused-parameters, and was manually inspected to make sure all callers
use the correct options (so none of these BUGs should be triggerable).

rebase: implement --merge via the interactive machinery
As part of an ongoing effort to make rebase have more uniform behavior,
modify the merge backend to behave like the interactive one, by
re-implementing it on top of the latter.
Interactive rebases are implemented in terms of cherry-pick rather than
the merge-recursive builtin, but cherry-pick also calls into the
recursive merge machinery by default and can accept special merge
strategies and/or special strategy options. As such, there really is
not any need for having both git-rebase--merge and
git-rebase--interactive anymore. Delete git-rebase--merge.sh and
instead implement it in builtin/rebase.c.
This results in a few deliberate but small user-visible changes:
* The progress output is modified (see t3406 and t3420 for examples)
* A few known test failures are now fixed (see t3421)
* bash-prompt during a rebase --merge is now REBASE-i instead of
REBASE-m. Reason: The prompt is a reflection of the backend in use;
this allows users to report an issue to the git mailing list with
the appropriate backend information, and allows advanced users to
know where to search for relevant control files. (see t9903)
testcase modification notes:
t3406: --interactive and --merge had slightly different progress output
while running; adjust a test to match the new expectation
t3420: these test precise output while running, but rebase--am,
rebase--merge, and rebase--interactive all were built on very
different commands (am, merge-recursive, cherry-pick), so the
tests expected different output for each type. Now we expect
--merge and --interactive to have the same output.
t3421: --interactive fixes some bugs in --merge! Wahoo!
t9903: --merge uses the interactive backend so the prompt expected is
now REBASE-i.
