These macros will produce better outputs when they fail than these existing
patterns using `ENSURE_TRUE(NS_SUCCEEDED(...))` or similar, so this is a bulk
rewrite of existing tests to use them.
It should also help with discoverability when people base their tests off of
other existing tests.

This patch moves EqualsIgnoreCase to ns[T]StringObsolete, and removes
the aCount argument, instead migrating callers to use `StringBeginsWith`
with a case-insensitive comparator.
In addition, nsTStringRepr::Compare was removed and replaced with either
calls to methods like `StringBeginsWith` or the global `Compare` method.
These changes required some modifications at call-sites but should make
the behaviour less surprising and more consistent.
Differential Revision: https://phabricator.services.mozilla.com/D148299
In addition to moving these methods to a more appropriate file, they were
simplified to make them easier to maintain in the future.
nsTStringRepr::Compare was extended to also work on char16_t strings, and the
case insensitive and other options were removed as they aren't necessary. This
required some changes to callers in the tree.
The EqualsIgnoreCase method was also simplified by using `std::string_view`.

The startup cache essentially leaks memory here for the old startup cache
data. My assumption here is that there can be dangling pointers into this
data so it's not safe to delete these old tables. Live language switching
is a relatively rare event, so this leak should be acceptable compared to
adding locking mechanisms to the underlying data.

Automatically generated path that adds flag `REQUIRES_UNIFIED_BUILD = True` to `moz.build`
when the module governed by the build config file is not buildable outside on the unified environment.
This needs to be done in order to have a hybrid build system that adds the possibility of combing
unified build components with ones that are built outside of the unified eco system.

Allow-list all Python code in tree for use with the black linter, and re-format all code in-tree accordingly.
To produce this patch I did all of the following:
1. Make changes to tools/lint/black.yml to remove include: stanza and update list of source extensions.
2. Run ./mach lint --linter black --fix
3. Make some ad-hoc manual updates to python/mozbuild/mozbuild/test/configure/test_configure.py -- it has some hard-coded line numbers that the reformat breaks.
4. Make some ad-hoc manual updates to `testing/marionette/client/setup.py`, `testing/marionette/harness/setup.py`, and `testing/firefox-ui/harness/setup.py`, which have hard-coded regexes that break after the reformat.
5. Add a set of exclusions to black.yml. These will be deleted in a follow-up bug (1672023).

This backs out all work from bug 1627075 as well as all of its
descendents. There were a few conflicts when backing this out but
overall it was pretty clean, so I would say it's a fairly mild
level of risk. Historically Nathan Froyd has reviewed these patches,
but he is no longer at Mozilla, and no one else is particularly
familiar with the code, so I am passing this off to RyanVM who has
at least been familiar with the history of the bug.

Given all of the MOZ_TRYs in WriteToDisk, it's entirely possible that
we occasionally exit it before writing everything out. WriteToDisk
additionally adds guards to try to ensure that we do not call it twice,
and that we do not try to read things out of the file via the memmapped
buffer after it has written to it. The latter should not generally be
a problem, since we write to a temp file and move that over at the end.
However, writing twice could be a problem as we modify our values'
mOffsets to keep track of their offsets within the resulting file.
Accordingly, this change simply moves the cleanup and guards into an
RAII helper to ensure they survive all of the early returns.

So far I have not found a way for this issue to cause bug 1656261, but
it's definitely plausible that there's something there. If we hit a
EXCEPTION_IN_PAGE_ERROR in GetBuffer, then we will exit the
DecompressEntry method with the entry's mData being set. In any
subsequent calls to GetBuffer for that key, we will return the
uninitialized memory. If we can hit this path with chrome.manifest,
then we would end up reading garbage from it, and could conclude that
xul.css is missing.
Whether this is the culprit or not, this is a problem that needs
addressing.

To be honest, it's still a mystery why we observed a regression in
sessionrestore_no_auto_restore in bug 1658732. The regression won't reproduce
on profiled runs, and the bad recordings happen before the supposedly offending
code ever actually runs. It feels most likely that it is a more or less random
confluence of factors causing a regression; however, 33% is too large of a
number to ignore.
The changes in this patch do not seem to yield the same regression, and they
are arguably more correct anyway. Instead of simply turning off the cache after
startup is finished, we simply avoid blocking waiting for the write from inside
GetBuffer. This way, if the write is not getting in the way of GetBuffer, we
can still benefit from a cached version of whatever it is we're looking for.

I don't think this will fully resolve the shutdown hangs associated
with this bug. The underlying problem is that writing the startup
cache during shutdown can take a long time. This seems like A Bad Thing,
and I have a mild leaning toward the thought that we shouldn't write the
startup cache at all during shutdown. However, I do think that trading
shutdown time regressions for startup time wins is probably good, so
I don't feel super comfortable making that change.
However, this change at least fixes the problem where we A) block the main
thread waiting for the write to finish, and B) are more likely to hit a
shutdown hang, since we concentrate all of the hang time in one phase,
rather than it being spread across the shutdown timeline. This is likely
the major change that the regressing bug introduced.
The unfortunate consequence is that if we try to GetBuffer during shutdown,
we will now read out of the omnijar. However, it should overall be better
since we'll be waiting on a (hopefully) small number of small reads rather
than a large write.

This is similar to the first patch in the stack, but instead of freeing the
entries on write, we free them when we send them to the parent to be written.
