A new submodule helper "git submodule embedgitdirs" to make it
easier to move embedded .git/ directory for submodules in a
superproject to .git/modules/ (and point the latter with the former
that is turned into a "gitdir:" file) has been added.

worktree: initialize return value for submodule_uses_worktrees
submodule: add absorb-git-dir function
move connect_work_tree_and_git_dir to dir.h
worktree: check if a submodule uses worktrees

"git mergetool" (without any pathspec on the command line) that is
not run from the top-level of the working tree no longer works in
Git v2.11, failing to get the list of unmerged paths from the output
of "git rerere remaining". This regression was introduced by
57937f70a0 ("mergetool: honor diff.orderFile", 2016-10-07).
This is because the pathnames output by the 'git rerere remaining'
command are relative to the top-level directory but the 'git diff
--name-only' command expects its pathname arguments to be relative
to the current working directory. To make everything consistent,
cd_to_toplevel before running 'git diff --name-only' and adjust any
relative pathnames.

Every once in a while someone complains to the mailing list to have
run into this weird assertion[1]. The usual response from the mailing
list is link to old discussions[2], and acknowledging the problem
stating it is known.
This patch accomplishes two things:
1. Switch assert() to die("BUG") to give a more readable message.
2. Take one of the cases where we hit a BUG and turn it into a normal
"there was something wrong with the input" message.
This assertion triggered for cases where there wasn't a programming
bug, but just bogus input. In particular, if the user asks for a
pathspec that is inside a submodule, we shouldn't assert() or
die("BUG"); we should tell the user their request is bogus.
The only reason we did not check for it, is the expensive nature
of such a check, so callers avoid setting the flag
PATHSPEC_STRIP_SUBMODULE_SLASH_EXPENSIVE. However when we die due
to bogus input, the expense of CPU cycles spent outweighs the user
wondering what went wrong, so run that check unconditionally before
dying with a more generic error message.
Note: There is a case (e.g. "git -C submodule add .") in which we call
strip_submodule_slash_expensive, as git-add requests it via the flag
PATHSPEC_STRIP_SUBMODULE_SLASH_EXPENSIVE, but the assert used to
trigger nevertheless, because the flag PATHSPEC_LITERAL was not set,
such that we executed
if (item->nowildcard_len < prefixlen)
item->nowildcard_len = prefixlen;
and prefixlen was not adapted (e.g. it was computed from "submodule/")
So in the die_inside_submodule_path function we also need handle paths,
that were stripped before, i.e. are the exact submodule path. This
is why the conditions in die_inside_submodule_path are slightly
different than in strip_submodule_slash_expensive.

The interactive rebase has the very special magic that a cherry-pick
that exits with a status different from 0 and 1 signifies a failure to
even record that a cherry-pick was started.
This can happen e.g. when a fast-forward fails because it would
overwrite untracked files.
In that case, we must reschedule the command that we thought we already
had at least started successfully.

An interactive rebase operates on a detached HEAD (to keep the reflog
of the original branch relatively clean), and updates the branch only
at the end.
Now that the sequencer learns to perform interactive rebases, it also
needs to learn the trick to update the branch before removing the
directory containing the state of the interactive rebase.
We introduce a new head_ref variable in a wider scope than necessary at
the moment, to allow for a later patch that prints out "Successfully
rebased and updated <ref>".

When the last command of an interactive rebase fails, the user needs to
resolve the problem and then continue the interactive rebase. Naturally,
the todo script is empty by then. So let's not complain about that!
To that end, let's move that test out of the function that parses the
todo script, and into the more high-level function read_populate_todo().
This is also necessary by now because the lower-level parse_insn_buffer()
has no idea whether we are performing an interactive rebase or not.

However, when an interactive rebase is continued without a "todo
