Poison was setup at the start of xpcom init when that was assumed to be early enough.
Since then, Poison was added to Maybe, and Maybe has been used everywhere, including in
our channel implementation. As a result, poison was being used before it was initialized.
This basically meant our poison pointers were being replaced with null instead, which
dances into some more UB than accessing a page we have actually allocated. Also, tsan
noticed that accesses to the value were racing with the initializer actually being
called!
A (dynamic) static initializer forces the poison initialization as we can reasonably
hope without getting CallOnce or singleton patterns involved.
Other changes:
* Cleaned up the outdated documentation for mozWritePoison (the alignment
restriction was removed in Bug 1414901)
* Removed the poison supression from TSan

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).

I have no idea what the issue is, but this fixes it. I figure it's not
worth putting too much effort into since this was just to make the tests
as DRY as possible, and not actually important.

No longer reset a moved-from Result to an error state, which required
UnusedZero<E>::GetDefaultValue, which was somewhat confusing, and might
also be inefficient. Leaving Result in a valid state, which might be a
success or error state is sufficient.

Per matrix discussion, this is safer to uplift (instead of relying on
the RedirectSink being released on the main thread).

Among other things, there were some misuses of std::forward, and
GenericErrorResult was (presumably accidentally) instatiated with
references as the template argument type, e.g. const nsresult&,
which circumvented the check for not calling it with NS_OK in
ResultExtensions.h

In most situations, JSONWriter users already know string lengths (either directly, or through `nsCString` and friends), so we should keep this information through JSONWriter and not recompute it again.
This also allows using JSONWriter with sub-strings (e.g., from a bigger buffer), without having to create null-terminated strings.
Public JSONWriter functions have overloads that accept literal strings.
