Implement a drop-in-replacement wrapper for `VirtualAlloc` which, rather
than returning immediately on failure, instead `::Sleep()`s and retries.
This will cause performance regressions in some (presumed-uncommon)
circumstances; this wrapper is therefore only enabled in Nightly, to
collect data on its efficacy and on the severity of those regressions.

Add the customary bevy of thread-safety annotations to the Mutex types
in memory/build.
Almost all existing instances of these Mutexes are already marked with
MOZ_UNANNOTATED, but this turns out not to matter: MOZ_UNANNOTATED has
no equivalent under clang's `-Wthread-safety` attributes. There are no
variables declared to be guarded by these mutexes, but they must still
be unlocked and relocked in principled ways -- or, alternatively, only
have unverifiable actions taken in appropriately-annotated code.
The primary offenders here are the `pthread_atfork` hooks; these can't
all be annotated precisely (and couldn't be checked even if they were),
so we simply mark them all as unanalyzable. The only other warning is
from a highly unusual (but already well-commented) bit in PHC.cpp where
we manually release an autolocked mutex before crashing.

Add the customary bevy of thread-safety annotations to the Mutex types
in memory/build.
Almost all existing instances of these Mutexes are already marked with
MOZ_UNANNOTATED, so there's not much else required for this patch. The
sole exception is a highly unusual (but already well-commented) bit in
PHC.cpp where we manually release an autolocked mutex before crashing.

jemalloc_stats takes an array for its second argument. It expects this
array to have enough space for all the bins, previously the maximum was set
as a magic number. To make it dependent on the configured bins this patch
replaces the compile-time constant with a function.

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.

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