Subject: rebase: make builtin and legacy script error messages the same

The conversion of the script version of rebase took messages that were
prefixed with "error:" and passed them along to die(), which adds a
"fatal:" prefix, thus resulting in messages of the form:

  fatal: error: cannot combine...

which seems redundant.  Remove the "error:" prefix from the builtin
version of rebase, and change the prefix from "error:" to "fatal:" in
the legacy script to match.

Subject: rebase: fix incompatible options error message

In commit f57696802c30 ("rebase: really just passthru the `git am`
options", 2018-11-14), the handling of `git am` options was simplified
dramatically (and an option parsing bug was fixed), but it introduced
a small regression in the error message shown when options only
understood by separate backends were used:

$ git rebase --keep --ignore-whitespace
fatal: cannot combine interactive options (--interactive, --exec,
--rebase-merges, --preserve-merges, --keep-empty, --root + --onto) with
am options (.git/rebase-apply/applying)

$ git rebase --merge --ignore-whitespace
fatal: cannot combine merge options (--merge, --strategy,
--strategy-option) with am options (.git/rebase-apply/applying)

Note that in both cases, the list of "am options" is
".git/rebase-apply/applying", which makes no sense.  Since the lists of
backend-specific options is documented pretty thoroughly in the rebase
man page (in the "Incompatible Options" section, with multiple links
throughout the document), and since I expect this list to change over
time, just simplify the error message.

Subject: t5407: add a test demonstrating how interactive handles --skip
 differently

The post-rewrite hook is documented as being invoked by commands that
rewrite commits such as commit --amend and rebase, and that it will
be called for each rewritten commit.

Apparently, the three backends handled --skip'ed commits differently:
  am: treat the skipped commit as though it weren't rewritten
  merge: same as 'am' backend
  interactive: treat skipped commits as having been rewritten to empty
     (view them as an empty fixup to their parent)

For now, just add a testcase documenting the different behavior (use
--keep to force usage of the interactive machinery even though we have
no empty commits).  A subsequent commit will remove the inconsistency in
--skip handling.

Subject: am, rebase--merge: do not overlook --skip'ed commits with
 post-rewrite

The post-rewrite hook is supposed to be invoked for each rewritten
commit.  The fact that a commit was selected and processed by the rebase
operation (even though when we hit an error a user said it had no more
useful changes), suggests we should write an entry for it.  In
particular, let's treat it as an empty commit trivially squashed into
its parent.

This brings the rebase--am and rebase--merge backends in sync with the
behavior of the interactive rebase backend.

Subject: 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.

Subject: git-legacy-rebase: simplify unnecessary triply-nested if

The git-legacy-rebase.sh script previously had code of the form:

if git_am_opt:
  if interactive:
    if incompatible_opts:
      show_error_about_interactive_and_am_incompatibilities
  if rebase-merge:
    if incompatible_opts
      show_error_about_merge_and_am_incompatibilities

which was a triply nested if.  However, the first conditional
(git_am_opt) and third (incompatible_opts) were somewhat redundant: the
latter condition was a strict subset of the former.  Simplify this by
moving the innermost conditional to the outside, allowing us to remove
the test on git_am_opt entirely and giving us the following form:

if incompatible_opts:
  if interactive:
    show_error_about_interactive_and_am_incompatibilities
  if rebase-merge:
    show_error_about_merge_and_am_incompatibilities

Subject: rebase: define linearization ordering and enforce it

Ever since commit 3f213981e44a ("add tests for rebasing merged history",
2013-06-06), t3425 has had tests which included the rebasing of merged
history and whose order of applied commits was checked.  Unfortunately,
the tests expected different behavior depending on which backend was in
use.  Implementing these checks was the following four lines (including
the TODO message) which were repeated verbatim three times in t3425:

    #TODO: make order consistent across all flavors of rebase
    test_run_rebase success 'e n o' ''
    test_run_rebase success 'e n o' -m
    test_run_rebase success 'n o e' -i

As part of the effort to reduce differences between the rebase backends
so that users get more uniform behavior, let's define the correct
behavior and modify the different backends so they all get the right
answer.  It turns out that the difference in behavior here is entirely
due to topological sorting; since some backends require topological
sorting (particularly when --rebase-merges is specified), require it for
all modes.  Modify the am and merge backends to implement this.

Performance Considerations:

I was unable to measure any appreciable performance difference with this
change.  Trying to control the run-to-run variation was difficult; I
eventually found a headless beefy box that I could ssh into, which
seemed to help.  Using git.git, I ran the following testcase:
    $ git reset --hard v2.20.0-rc1~2
    $ time git rebase --quiet v2.20.0-rc0~16

I first ran once to warm any disk caches, then ran five subsequent runs
and recorded the times of those five.  I observed the following results
for the average time:

     Before this change:
       "real" timing: 1.340s (standard deviation: 0.040s)
       "user" timing: 1.050s (standard deviation: 0.041s)
       "sys"  timing: 0.270s (standard deviation: 0.011s)
     After  this change:
       "real" timing: 1.327s (standard deviation: 0.065s)
       "user" timing: 1.031s (standard deviation: 0.061s)
       "sys"  timing: 0.280s (standard deviation: 0.014s)

Measurements aside, I would expect the timing for walking revisions to
be dwarfed by the work involved in creating and applying patches, so
this isn't too surprising.  Further, while somewhat counter-intuitive,
it is possible that turning on topological sorting is actually a
performance improvement: by way of comparison, turning on --topo-order
made fast-export faster (see
https://public-inbox.org/git/20090211135640.GA19600@coredump.intra.peff.net/).

Subject: 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.
