When a third-party tool periodically runs `git status` in order to keep
track of the state of the working tree, it is a bad idea to lock the
index: it might interfere with interactive commands executed by the
user, e.g. when the user wants to commit files.
Git for Windows introduced the `--no-lock-index` option a long time ago
to fix that (it made it into Git for Windows v2.9.2(3)) by simply
avoiding to write that file.
The downside is that the periodic `git status` calls will be a little
bit more wasteful because they may have to refresh the index repeatedly,
only to throw away the updates when it exits. This cannot really be
helped, though, as tools wanting to get a periodic update of the status
have no way to predict when the user may want to lock the index herself.
Sadly, a competing approach was submitted (by somebody who apparently
has less work on their plate than this maintainer) that made it into
v2.15.0 but is *different*: instead of a `git status`-only option, it is
an option that comes *before* the Git command and is called differently,
too.
Let's give previous users a chance to upgrade to newer Git for Windows
versions by handling the `--no-lock-index` option, still, though with a
big fat warning.

The CI builds are failing for Mac OS X due to a change in the
location of the perforce cask. The command outputs the following
error:
+ brew install caskroom/cask/perforce
Error: caskroom/cask was moved. Tap homebrew/cask-cask instead.
Preface the "brew install caskroom/cask/perforce" with the old
way of installing perforce, and only try this method if the
"brew install perforce" fails.
The existing way to use caskroom was added in 672f51cb (travis-ci:
fix Perforce install on macOS, 2017-01-22) and the justification
is that the "brew install perforce" can fail due to a hash
mis-match. The mismatch is due to the official Perforce distro
updating the published binaries without updating the version
string. CI servers are typically fresh virtual machines, so that
issue should not arise in automated builds.
Even if a build server is re-used and hits the hash mis-match,
it will fall back to the "new" mechanism which is currently
failing, but may be fixed independently of this change.

As it is the first chance to clean up during a rebase in quite a while,
this is a bit bigger. Mostly, commits and branches have been shuffled
around, the FSCache patches (while still not consolidated enough to
submit to the Git mailing list for review) are at least compile-clean
now, and the newest iteration of the `git add -i`/`git add -p` patches

It still fails! *Still!*
Even after upgrading the cask's definition in the PR
https://github.com/Homebrew/homebrew-cask/pull/70981 does it fail.
The explanation is, as Gábor Szeder dug out from the commit history:
the local definitions might get stale and need to be updated.
So let's just update them in case `brew cask install perforce` fails,
and just try again!
This will still fail, of course, when `homebrew-cask` falls behind
Perforce's release schedule. But once it is updated, we can now simply
re-run the failed jobs and they will pick up that update.
As to updating `homebrew-cask`: I started automating this, via
https://dev.azure.com/gitgitgadget/git/_build?definitionId=11&_a=summary
(I plan on finishing it once the next Perforce upgrade comes around.)

In the previous commit, we moved the location of the system config to
`C:\Program Files\Git\etc\gitconfig`, to give users a reliable location
for the system config.
Previously, we had introduced `C:\ProgramData\Git\config` as such a
location.
However, the purpose of `C:\ProgramData\Git\config` was always for the
installed Git for Windows to share its configured options. Every upgrade
will modify the settings in that file according to what the user
specified when running Git for Windows' installer. So it is not really a
file whose ownership is shared between all Git implementations, contrary
to what the location suggests.
Also, it was totally confusing to many users that there was a "system"
config and then yet another "sort of system" config that did not even
have a corresponding `git config` option such as `--system`.
Further, Portable Git should probably never look at
`C:\ProgramData\Git\config` to begin with: this makes it rather
non-Portable ;-)
Finally, support for `C:\ProgramData\Git\config` never really caught on:
only libgit2 implemented it, but even JGit (which might be used by more
users than libgit2-based applications by grace of backing Android
Studio) did not.
Therefore, let's finally admit that it was a mistake to introduce
`C:\ProgramData\Git\config` and remove support for it.
This reverts commit bcbbb4f89f.

This moves the system config into a more logical location: the `mingw64`
part of `C:\Program Files\Git\mingw64\etc\gitconfig` never made sense,
as it is a mere implementation detail. Let's skip the `mingw64` part and
move this to `C:\Program Files\Git\etc\gitconfig`.
Side note: in the rare (and not recommended) case a user chooses to
install 32-bit Git for Windows on a 64-bit system, the path will of
course be `C:\Program Files (x86)\Git\etc\gitconfig`.
The next step after this patch is to scrap support for
`C:\ProgramData\Git\config`, which never really made sense to users, and
which is inconsistent with non-Windows versions of Git, anyway.
Background: During the Git for Windows v1.x days, the system config was
located at `C:\Program Files (x86)\Git\etc\gitconfig`. With Git for
Windows v2.x, it moved to `C:\Program Files\Git\mingw64\gitconfig` (or
`C:\Program Files (x86)\Git\mingw32\gitconfig`).
Obviously, this new location was not stable (because of the "mingw64"
part) and this maintainer thought that it was a splendid time to
introduce a "super-system" config, with a constant location, that would
be shared by all Git implementations. Hence `C:\ProgramData\Git\config`
was born.
What we *should* have done instead is to move the location to the
top-level `etc` directory instead of the `mingw64\etc` one (or
`mingw32\etc` for 32-bit versions).
Likewise, we should have treated the system `gitattributes` in a similar
manner.
This patch makes it so.
Obviously, we are cautious to do this only for the known install
locations `/mingw64` and `/mingw32`; If anybody wants to override that
while building their version of Git (e.g. via `make prefix=$HOME`), we
leave the default location of the system config and gitattributes alone.

Use argv_array to build an array of strings instead of open-coding it.
This simplifies the code a bit.
We also need to make the specs parameter of push(), push_dav() and
push_git() const to match the argv member of the argv_array. That's
fine, as all three only actually read from the specs array anyway.

Make use of utf8_strnwidth()'s feature to skip ANSI escape sequences
instead of open-coding it. This shortens the code and makes it more
consistent.
This changes the behavior, though: The old code skips all kinds of
Control Sequence Introducer sequences, while utf8_strnwidth() only skips
the Select Graphic Rendition kind, i.e. those ending with "m". They are
used for specifying color and font attributes like boldness. The only
other kind of escape sequence we print in Git is Erase in Line, ending
with "K". That's not used for columnar output, so this difference
actually doesn't matter here.

The first step for deleting an item from a linked list is to locate the
item preceding it. Be more careful in release_request() and handle an
empty list. This only has consequences for invalid delete requests
(removing the same item twice, or deleting an item that was never added
to the list), but simplifies the loop condition as well as the check
after the loop.
Once we found the item's predecessor in the list, update its next
pointer to skip over the item, which removes it from the list. In other
words: Make the item's successor the successor of its predecessor.
(At this point entry->next == request and prev->next == lock,
respectively.) This is a bit simpler and saves a pointer dereference.

git stash push does not recursively stash submodules, but if
submodule.recurse is set, it may recursively reset --hard them. Having
only the destructive action recurse is likely to be surprising
behaviour, and unlikely to be desirable, so the easiest fix should be to
ensure that the call to git reset --hard never recurses into submodules.
This matches the behavior of check_changes_tracked_files, which ignores
submodules.

output, similar to the $(QUIET_<x>) family of variables.
In the case where one wants to inspect the output hidden by
$(QUIET_<x>), one could define $(V) for verbose output. In the
%.cocci.patch target, this was not implemented.
Move the output suppression into the $(QUIET_SPATCH) variable which is
