I went through the docs and fixed up a few things. I also removed the other
version that was imported under XPCOM, updated a few obsolete MDN links that
now have updated docs, and deleted some ancient Bonsai links.

Under Python 3 on Windows we sometimes get an OSError which may be a
race with the process exiting. There's not much we can do about
exceptions during shutdown so just ignore them.

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).

Currently AWSY-with-DMD doesn't work on Windows. This is because `fix-stacks`
is initialized lazily, and by the time the initialization happens some file
descriptors for files are open, and that leads to some major Python2-on-Windows
sadness as described in the big comment in the commit.
To fix the problem, this commit adds an `init` function to `fix_stacks.py` so
that `fix-stacks` can be initialized eagerly, hopefully before any file
descriptors for files are open.
For `dmd.py`, other than fixing the AWSY problems, this has little effect,
because `fix-stacks` is always initialized.
For `utils.py`, which is used to process the output of most tests, this has a
more noticeable effect: the `fix-stacks` process is always spawned, rather than
being spawned only when needed. If no stack traces appear in the test output,
this means that `fix-stacks` is spawned unnecessarily. But it's cheap to spawn;
the expensive part only happens when stack traces start getting fixed. So I
think this change in behaviour is acceptable.
Furthermore, the commit adds a `finish` function to `fix_stacks.py`, so that
the `fix-stacks` process can be explicitly shut down. This has never been done
for processes spawned for any of the stack fixing scripts. It's never caused
problems on Linux/Mac, but it seems to be necessary on Windows to avoid
similar "this file is locked" problems with the test_dmd.js test.
The commit also renames some things to more standard Python style, e.g.
`json_mode` instead of `jsonMode`.
Finally, Android tests use `utils.py` from the repository but `fix_stacks.py`
from the Android host utils. Because the two scripts must be updated in tandem,
this commit also updates the Android host utils to a version that contains the
updated `fix_stacks.py`. Thanks to aerickson for packaging up the new Android
host utils and providing the change to the `hostutils.manifest` file.

This commit removes `test_fix_stack_using_bpsyms.py`. That test can't easily be
modified to work with `fix_stacks.py` because it relies on internal
implementation details of `fix_stack_using_bpsym.py`. The unit testing done in
the `fix-stacks` repo provides test coverage that is as good or better.

Now that `fix_stacks.py` is being used instead of `fix_macosx_stack.py`,
stack-fixing time has dropped from about 14 minutes to about 30 seconds on my
new MacBook Pro.
Also, print a warning about stacks not being fixed if `MOZ_DISABLE_STACK_FIX`
is set. This warning shows up at the start of the test run.
Also, print a warning about stack fixing slowness, because 30 seconds is long
enough to possibly be surprising. This warning shows up just before the first
stack frame is fixed, like this:
```
Assertion failure: false (BEEP BOOP), at /home/njn/moz/au3/dom/base/nsGlobalWindowOuter.cpp:1342
Initializing stack-fixing for the first stack frame, this may take a while...

Specifically:
- handle input that doesn't end in a newline;
- only pass lines that match the regexp to `fix-stacks`.
These changes are needed for `utils.py` to use `fix_stacks.py` without
problems.

On Linux and Mac, this makes `dmd.py` *much* faster when it is first run on a
DMD data file.
On Windows, this makes DMD actually usable locally. Previously the stacks
weren't fixed and so were rubbish.

When reworking the script each entry holding a function name was replaced by a
dictionary holding both the function name and its size. This significantly
increased memory consumption as using a full-fledged dictionary for only two
fields is very space inefficient. This patch uses a named tuple instead of a
dictionary for every entry, reducing memory consumption by almost four times.

This patch changes the way we search symbols when fixing up a stack.
Previously we would find the closest PUBLIC or FUNC entry lower than a given
address. Because of how symbol files were processed we preferred PUBLIC
entries to FUNC ones. Now we look first for the function that contains the
address (obtained from the FUNC entries) then if none is available we look for
the closest, lower PUBLIC entry.

This includes both the vanilla sources we haven't forked and the client
sources that we have. Client patches were applied manually up to version
69c2c51dd89965d234eec16e3a9353634831916b. The following changes were not
included as they break merging segments corresponding to libxul.so in the
module list:
8915f7be39448d9257b6da3ad0233944d1d9a92a

94b6309aecaddfcf11672f6cfad9575d68ad3b40
With these changes applied two entries for libxul.so are generated, the second
one is bogus and prevents symbolication from working correctly.
The build system and some of the tools relying on breakpad were also updated
to work with the new version.
