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 requires a workaround for the use of __wrap_dladdr, which can't be
used in logalloc-replay. The workaround involves making __wrap_dladdr
expand to dladdr, but that makes the definition ElfLinker.h conflict
with the one in the Android system headers, so we change it to match,
and adjust ElfLinker.cpp accordingly.
And while here, fix the condition in mozglue/misc to match the condition
around including Linker.h in StackWalk.cpp itself.

This is a rebase of a 7-year-old patch that was r=taras. Back then it
was waiting for breakpad changes that never were reviewed. However,
since then, bug 1486524 made the linker always map uncompressed files
directly, making it less necessary to report the library mappings to
the crash reporter, and bug 1291377 disabled the linker altogether on
Android 6.0+, which makes report_mapping unused at all in that case.

RC should be non-copyable. It already is non-copyable in the atomic variant,
but not in the non-atomic variant. This ensures that RefCounted is also
non-copyable, which prevents that classes deriving from RefCounted get
accidentally copied.
Also, RC's operator= should be defined only in debug builds. As already
described in a code comment, it's only used in debug builds (to assign the
dead value), and otherwise no modifications other than incrementing &
decrementing should be possible.

Apps targeting SDK 29 are not allowed to open /dev/ashmem directly, and
instead must use NDK functions. Those functions are only available in
SDK 26 and higher, so we need this shim to use the functions if they
are available, else fallback to opening /dev/ashmem directly.

This changeset is a simple find and replace of `MOZ_FALLTHROUGH` and `[[fallthrough]]`.
Unfortunately, the MOZ_FALLTHROUGH_ASSERT macro (to assert on case fallthrough in debug builds) is still necessary after switching from [[clang::fallthrough]] to [[fallthrough]] because:
* MOZ_ASSERT(false) followed by [[fallthrough]] triggers a -Wunreachable-code warning in DEBUG builds
* but MOZ_ASSERT(false) without [[fallthrough]] triggers a -Wimplicit-fallthrough warning in NDEBUG builds.

The current situation is suboptimal, where we have the same goop
repeated in multiple files, and where things kinda sorta work out fine
thanks to the linker for files that would have been forbidden, except
when the linker doesn't do its job, which apparently happen on
mingwclang builds.
This change only really covers C++ code using operator new/delete, and
not things that would be using malloc/free, because it's easier.
malloc/free is left for a followup.

Some parts of mozglue used to be STL wrapped because mozalloc used to be
a separate library, but that was changed a while ago (in bug 868814, 4
years ago), and those wrappings are not necessary anymore.

We're going to convert the test to a gtest, and it's simpler not to have
to deal with finding the path to the testcase zip files. They're small
enough anyways, and can be inserted as raw binary data via some assembly
magic. This being android-only code, we don't need extreme portability
here. This is the same trick we use in
config/external/icu/data/icudata_gas.S.

The linker has x86-64 support but currently fails to compile. This patch
fixes these compile errors to make it build under x86-64.

__wrap_dlerror uses a single pointer for all threads, which means one
thread could get the dlerror result from another thread. Normally this
wouldn't cause crashes. However, because dlerror results come from a
per-thread buffer, if a thread exits and our saved dlerror result came
from that thread, the saved pointer could then refer to invalid memory.
The proper way to fix this is to use TLS and have a per-thread pointer
for __wrap_dlerror. However, instead of using up a TLS slot, this patch
keeps the single pointer for custom messages, and fallback to per-thread
dlerror call for system messages. While the race condition still exists,
I think the risk is acceptable. Even when races occur, they should no
longer cause crashes.

When we modify the debug map, we could be racing with the system linker,
either when we modify the entries or when we change page protection
flags. To fix the race, we need to take the system linker's internal
lock when we perform any kind of modification on the debug map.
One way to hold the system linker lock is to call dl_iterate_phdr, and
perform our actions inside the callback, which is invoked with the
lock being held. However, dl_iterate_phdr is only present on Android
5.0+, and even then, dl_iterate_phdr is only protected by the linker
lock on Android 6.0+.
This means that with this patch, we can only safely modify the debug map
on Android 6.0+, which I think is acceptable for an operation that only
benefits a debugger.

We are apparently still crashing even after mprotect() with write flag
returns successfully. This patch reads the flags again after mprotect()
returns, and hopefully the flags will tell the truth of whether the page

It was necessary back when we were doing decompression from a signal
handler, because we couldn't then have zlib call malloc, but we don't
do that anymore, so the whole wrapping is effectively unused.
With the wrapping gone, we manually initialize the zalloc, zfree and
opaque fields, as specified in the zlib documentation.
