git cherry-pick fails when picking a non-ff commit that is empty. The advice
given with the failure is that a git-commit --allow-empty should be issued to
explicitly add the empty commit during the cherry pick. This option allows a
user to specify before hand that they want to keep the empty commit. This
eliminates the need to issue both a cherry pick and a commit operation.

This macro already evaluates to the correct type, as it
casts the string literal to "unsigned char *" itself
(and callers who want the literal can use the _LITERAL
form).

When cherry-pick fails it offers a helpful hint about how to
proceed. The hint tells the user how to do the cleanup
needed by the conflicted cherry-pick and finish the job after
conflict resolution. In case of cherry-pick --no-commit, the
hint goes too far. It tells the user to finish up with
'git commit'. That is not what this git-cherry-pick was
trying to do in the first place.
Restrict the hint in case of --no-commit to avoid giving this
extra advice.
Also, add a test verifying the reduced hint for the --no-commit
version of cherry-pick.

Expose the cherry-picking machinery through a public
sequencer_pick_revisions() (renamed from pick_revisions() in
builtin/revert.c), so that cherry-picking and reverting are special
cases of a general sequencer operation. The cherry-pick builtin is
now a thin wrapper that does command-line argument parsing before
calling into sequencer_pick_revisions(). In the future, we can write
a new "foo" builtin that calls into the sequencer like:
memset(&opts, 0, sizeof(opts));
opts.action = REPLAY_FOO;
opts.revisions = xmalloc(sizeof(*opts.revs));
parse_args_populate_opts(argc, argv, &opts);
init_revisions(opts.revs);
sequencer_pick_revisions(&opts);
This patch does not intend to make any functional changes. Check
with:
$ git blame -s -C HEAD^..HEAD -- sequencer.c | grep -C3 '^[^^]'

Now that "git reset" no longer implicitly removes .git/sequencer that
the operator may or may not have wanted to keep, the logic to write a
backup copy of .git/sequencer and remove it when stale is not needed
any more. Simplify the sequencer API and repository layout by
dropping it.

To explicitly remove the sequencer state for a fresh cherry-pick or
revert invocation, introduce a new subcommand called "--reset" to
remove the sequencer state.
Take the opportunity to publicly expose the sequencer paths, and a
generic function called "remove_sequencer_state" that various git
programs can use to remove the sequencer state in a uniform manner;
"git reset" uses it later in this series. Introducing this public API
is also in line with our long-term goal of eventually factoring out
functions from revert.c into a generic commit sequencer.
