Instead of snprintf.
Because some standalone code uses those functions directly or indirectly,
and PrintfTarget lives in mozglue, they now need to depend on mozglue
instead of mfbt. Except logalloc/replay, which cherry-picks what it
uses.

The current implementation is a regression on microbenchmarks that
reallocate allocations that go over gPageSize * 32 compared to memcpy().

In clang-cl builds, thanks to clang-cl's defining of `_MSC_VER`, this function was not marked `noexcept`. This led clang to believe that it could call `arena_t`'s constructor without checking for null.
I suppose we could scope the condition down to real MSVC, but since we don't support that anymore, we can just stop checking.

While all toolkit and js-based projects make use of mfbt, some others,
like tools/crashreporter and tools/update-packaging, don't.
So instead of including mfbt from the top-level directory, include it
from the relevant project top-level mozbuilds.
This allows to remove the dependency on mfbt files in the hash for the
minidump-stackwalk and mar-tools toolchains.

Sheriff note: We should keep this regardless of whether bug 1675600 sticks.
The comment above SmokeDMD's `RunTests()` says "This test relies on the compiler not doing various optimizations ... So we compile it with -O0 (or equivalent)".
That suggests that LTO should also be disallowed.

Due to lack of `CXX_TYPE`, clang-cl builds were accidentally taking the `else` branch where the `-O0` was ignored/unrecognized. This went unnoticed for a long time until it busted the landing of bug 1677726.
While here, fix the intent of SmokeDMD: `-Og-` is a silent no-op in clang-cl, so it's not actually disabling anything.

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 warning turns into an error on automation, and is only due to the
fact that newer SDKs have a declaration for it with a version guard, but
we're actually using our own definition of the function, so whether it's
available in older versions of macOS is irrelevant.

Previously there was one field here named small_max, and it wasn't obvious
from the name alone whether this meant the end of the
quantum-spaced sizes or the subpage sizes. Instead place both these fields
into the structure with clearer names. Besides, a later page will need
subpage_max.

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.

The MOZ_MUST_USE macro is defined as clang's and gcc's nonstandard __attribute__((warn_unused_result)). Now that we compile as C++17 by default (bug 1560664), we can replace MOZ_MUST_USE with C++17's standard [[nodiscard]] attribute.
We can also stop #including mozilla/Attributes.h because it was only needed for its MOZ_MUST_USE declaration.

CLOSED TREE
We don't need these macros anymore, for two reasons:
1. We have static analysis to provide the same sort of checks via `MOZ_RAII`
and friends.
2. clang now warns for the "temporary that should have been a declaration" case.
The extra requirements on class construction also show up during debug tests
as performance problems.
This change was automated by using the following sed script:
```
# Remove declarations in classes.
/MOZ_DECL_USE_GUARD_OBJECT_NOTIFIER/d
/MOZ_GUARD_OBJECT_NOTIFIER_INIT/d
# Remove individual macros, carefully.
{
# We don't have to worry about substrings here because the closing
# parenthesis "anchors" the match.

s/MOZ_GUARD_OBJECT_NOTIFIER_PARAM_TO_PARENT)/)/g;

# Remove the longer identifier first.
s/MOZ_GUARD_OBJECT_NOTIFIER_ONLY_PARAM_TO_PARENT//g;
s/MOZ_GUARD_OBJECT_NOTIFIER_ONLY_PARAM//g;
}
# Remove the actual include.
\@# *include "mozilla/GuardObjects.h"@d
```
and running:
```
find . -name \*.cpp -o -name \*.h | grep -v 'GuardObjects.h' |xargs sed -i -f script 2>/dev/null
mach clang-format
