In read_protected_config(), check whether each file name is NULL before
attempting to read it, and add a BUG() call to
git_config_from_file_with_options() to make this error easier to catch
in the future.
The NULL checks mirror what do_git_config_sequence() does (which
read_protected_config() is modeled after). Without these NULL checks,
multiple tests fail with "make SANITIZE=address", e.g. in the final test
of t4010, xdg_config is NULL causing us to call fopen(NULL).

Administrators of a managed Git environment (like the one at $DAYJOB)
might want to quantify the performance change of fetches with and
without filters from the client's point of view, and also detect if a
server does not support it. Therefore, log the filter information being
sent to the server whenever a fetch (or clone) occurs. Note that this is
not necessarily the same as what's specified on the CLI, because during
a fetch, the configured filter is used whenever a filter is not
specified on the CLI.

Previously, if the user:
* Had no local changes before starting the merge
* A merge strategy makes changes to the working tree/index but returns
with exit status 2
Then we'd call restore_state() to clean up the changes and either let
the next merge strategy run (if there is one), or exit telling the user
that no merge strategy could handle the merge. Unfortunately,
restore_state() did not clean up the changes as expected; that function
was a no-op if the stash was a null, and the stash would be null if
there were no local changes before starting the merge. So, instead of
"Rewinding the tree to pristine..." as the code claimed, restore_state()
would leave garbage around in the index and working tree (possibly
including conflicts) for either the next merge strategy or for the user
after aborting the merge. And in the case of aborting the merge, the
user would be unable to run "git merge --abort" to get rid of the
unintended leftover conflicts, because the merge control files were not
written as it was presumed that we had restored to a clean state
already.
Fix the main problem by making sure that restore_state() only skips the
stash application if the stash is null rather than skipping the whole
function.
However, there is a secondary problem -- since merge.c forks
subprocesses to do the cleanup, the in-memory index is left out-of-sync.
While there was a refresh_cache(REFRESH_QUIET) call that attempted to
correct that, that function would not handle cases where the previous
merge strategy added conflicted entries. We need to drop the index and
re-read it to handle such cases.
(Alternatively, we could stop forking subprocesses and instead call some
appropriate function to do the work which would update the in-memory
index automatically. For now, just do the simple fix.)
Also, add a testcase checking this, one for which the octopus strategy
fails on the first commit it attempts to merge, and thus which it
cannot handle at all and must completely bail on (as per the "exit 2"
code path of commit 98efc8f3d8 ("octopus: allow manual resolve on the
last round.", 2006-01-13)).

Merge strategies can:
* succeed with a clean merge
* succeed with a conflicted merge
* fail to handle the given type of merge
If one is thinking in terms of automatic mergeability, they would use
the word "fail" instead of "succeed" for the second bullet, but I am
focusing here on ability of the merge strategy to handle the given
inputs, not on whether the given inputs are mergeable. The third
category is about the merge strategy failing to know how to handle the
given data; examples include:
* Passing more than 2 branches to 'recursive' or 'ort'
* Passing 2 or fewer branches to 'octopus'
* Trying to do more complicated merges with 'resolve' (I believe
directory/file conflicts will cause it to bail.)
* Octopus running into a merge conflict for any branch OTHER than
the final one (see the "exit 2" codepath of commit 98efc8f3d8
("octopus: allow manual resolve on the last round.", 2006-01-13))
That final one is particularly interesting, because it shows that the
merge strategy can muck with the index and working tree, and THEN bail
and say "sorry, this strategy cannot handle this type of merge; use
something else".
Further, we do not currently expect the individual strategies to clean
up after themselves, but instead expect builtin/merge.c to do so. For
it to be able to, it needs to save the state before trying the merge
strategy so it can have something to restore to. Therefore, remove the
shortcut bypassing the save_state() call.
There is another bug on the restore_state() side of things, so no
testcase will be added until the next commit when we have addressed that
issue as well.

There are multiple issues at play here:
1) If `git merge` is invoked with staged changes, it should abort
without doing any merging, and the user's working tree and index
should be the same as before merge was invoked.
2) Merge strategies are responsible for enforcing the index == HEAD
requirement. (See 9822175d2b ("Ensure index matches head before
invoking merge machinery, round N", 2019-08-17) for some history
around this.)
3) Merge strategies can bail saying they are not an appropriate
handler for the merge in question (possibly allowing other
strategies to be used instead).
4) Merge strategies can make changes to the index and working tree,
and have no expectation to clean up after themselves, *even* if
they bail out and say they are not an appropriate handler for
the merge in question. (The `octopus` merge strategy does this,
for example.)
5) Because of (3) and (4), builtin/merge.c stashes state before
trying merge strategies and restores it afterward.
Unfortunately, if users had staged changes before calling `git merge`,
builtin/merge.c could do the following:
* stash the changes, in order to clean up after the strategies
* try all the merge strategies in turn, each of which report they
cannot function due to the index not matching HEAD
* restore the changes via "git stash apply"
But that last step would have the net effect of unstaging the user's
changes. Fix this by adding the "--index" option to "git stash apply".
While at it, also squelch the stash apply output; we already report
"Rewinding the tree to pristine..." and don't need a detailed `git
status` report afterwards. Also while at it, switch to using strvec
so folks don't have to count the arguments to ensure we avoided an
off-by-one error, and so it's easier to add additional arguments to
the command.

builtin/merge is setup to allow multiple strategies to be specified,
and it will find the "best" result and use it. This is defeated if
some of the merge strategies abort early when they cannot handle the
merge. Fix the logic that calls recursive and ort to not do such an
early abort, but instead return "2" or "unhandled" so that the next
strategy can try to handle the merge.
Coming up with a testcase for this is somewhat difficult, since
recursive and ort both handle nearly any two-headed merge (there is
a separate code path that checks for non-two-headed merges and
already returns "2" for them). So use a somewhat synthetic testcase
of having the index not match HEAD before the merge starts, since all
merge strategies will abort for that.

As noted in the last commit and the links therein (especially commit
9822175d2b ("Ensure index matches head before invoking merge machinery,
round N", 2019-08-17), we have had a very long history of problems with
failing to enforce the requirement that index matches HEAD when starting
a merge.
The "trivial merge" logic in builtin/merge.c is yet another such case
we previously missed. Add a check for it to ensure it aborts if the
index does not match HEAD, and add a testcase where this fix is needed.
Note that the fix here would also incidentally be an alternative fix
for the testcase added in the last patch, but the fix in the last patch
is still needed when multiple merge strategies are in use, so tweak the
testcase from the previous commit so that it continues to exercise the
codepath added in the last commit.

As noted in commit 9822175d2b ("Ensure index matches head before
invoking merge machinery, round N", 2019-08-17), we have had a very
long history of problems with failing to enforce the requirement that
index matches HEAD when starting a merge. One of the commits
referenced in the long tale of issues arising from lax enforcement of
this requirement was commit 55f39cf755 ("merge: fix misleading
pre-merge check documentation", 2018-06-30), which tried to document
the requirement and noted there were some exceptions. As mentioned in
that commit message, the `resolve` strategy was the one strategy that
did not have an explicit index matching HEAD check, and the reason it
didn't was that I wasn't able to discover any cases where the
implementation would fail to catch the problem and abort, and didn't
want to introduce unnecessary performance overhead of adding another
check.
Well, today I discovered a testcase where the implementation does not
catch the problem and so an explicit check is needed. Add a testcase
that previously would have failed, and update git-merge-resolve.sh to
have an explicit check. Note that the code is copied from 3ec62ad9ff
("merge-octopus: abort if index does not match HEAD", 2016-04-09), so
that we reuse the same message and avoid making translators need to
translate some new message.

When the index does not match HEAD, the merge strategies are responsible
to detect that condition and abort. The merge-ort-wrappers had code to
implement this and meant to copy the error message from merge-recursive
but deviated in two ways, both due to the message in merge-recursive
being processed by another function that made additional changes:
* It added an implicit "error: " prefix
* It added an implicit trailing newline
We can get these things by making use of the error() function.

When callers are using `cat-file` via one of the stdin-driven `--batch`
modes, all input is newline-delimited. This presents a problem when
callers wish to ask about, e.g. tree-entries that have a newline
character present in their filename.
To support this niche scenario, introduce a new `-z` mode to the
`--batch`, `--batch-check`, and `--batch-command` suite of options that
instructs `cat-file` to treat its input as NUL-delimited, allowing the
individual commands themselves to have newlines present.
The refactoring here is slightly unfortunate, since we turn loops like:
while (strbuf_getline(&buf, stdin) != EOF)
into:
while (1) {
int ret;
if (opt->nul_terminated)
ret = strbuf_getline_nul(&input, stdin);
else
ret = strbuf_getline(&input, stdin);
if (ret == EOF)
break;
}
It's tempting to think that we could use `strbuf_getwholeline()` and
specify either `\n` or `\0` as the terminating character. But for input
on platforms that include a CR character preceeding the LF, this
wouldn't quite be the same, since `strbuf_getline(...)` will trim any
trailing CR, while `strbuf_getwholeline(&buf, stdin, '\n')` will not.
In the future, we could clean this up further by introducing a variant
of `strbuf_getwholeline()` that addresses the aforementioned gap, but
that approach felt too heavy-handed for this pair of uses.
Some tests are added in t1006 to ensure that `cat-file` produces the
same output in `--batch`, `--batch-check`, and `--batch-command` modes
with and without the new `-z` option.

A future commit will want to ensure that various `--batch`-related
options produce the same output whether their input is newline
terminated, or NUL terminated (and a to-be-implemented `-z` option
exists).
To prepare for this, extract the given input(s) into separate variables
to that their LF characters can easily be converted into NUL bytes when
testing the new `-z` mode.
This is consistent with other tests in t1006 (which these days is no
longer a shining example of our CodingGuidelines).
