8b7fc2dba5 Bug 1884054 - Stop wrapping HeapAlloc-family of functions. r=pbone 
The functions were wrapped in bug 1280578 mainly for rust, which used
these functions for its global allocator. However, that use case went
away with bug 1514122, where we've set up our own global allocator for
rust that calls the malloc-family of functions directly instead.

Back in that bug, we left the HeapAlloc wrapping for other use cases,
but there are few of them left, but we're now hitting another problem,
where we actually do want to be able to HeapFree pointers that might
have been allocated by system libraries, and the wrapping is getting
on the way of this actually working.

a0f64f2204 Bug 1857841 - pt 8. Use CHUNK_MAP_FRESH for double-purged pages r=glandium 
Using CHUNK_MAP_FRESH for double purged pages is better than overloading
the CHUNK_MAP_DECOMMITTED bit with two different semantics.  It also allows
us to simplify some code.

02fb924e9b Bug 1857841 - pt 9. Count fresh and madvised memory separately r=glandium 
This memory was previously measured as part of committed memory.  However
depending on the OS it will often not be committed.  It's more accurate to
count it separately as part of mozjemalloc's cache of unused pages.

This patch adds counters for both fresh and madvised memory and no-longer
counts either as "committed" as it previously did.

This has the side effect of changing decisions based on the size of this
cache such as when to purge memory.

This breaks the old invariant that there are no committed pages that aren't
either allocated or dirty.  There is now also new code in DeallocChunk that

bc4ccb1adf Bug 1857841 - pt 5. Simplify decommit logic in SplitRun() r=glandium 
The decommit logic is now only used when MALLOC_DECOMMIT is defined.  The other
page bits ( CHUNK_MAP_MADVISED and CHUNK_MAP_FRESH) are cleared when the page
is initialised.  This avoids leaving the chunk map in an inconsistent state if
pages_commit should fail.

These changes will make some following patches simpler.

a3e8abd326 Bug 1858250 - malloc_initialized should not be SequentiallyConsistent. r=glandium 
I think ReleaseAcquire semantics are sound here.

It might be that relaxed is fine too, but that might be technically
unsound because it could make the writes in malloc_init_hard not visible
to the other threads in time.

Depends on D190623

760aa24874 Bug 1850008 - pt 2. Poison at most the first 64 bytes of a memory cell r=jesup,glandium 
This patch alters mozjemalloc's poisoning to poison only the first 64 bytes
of (most) memory cells.  It has this behaviour in late beta and release
builds and keeps the original "poison all" behaviour for nightly and early
beta builds.

A later patch will make this a parameter and set it to 256.
