In PLDHashTable the equivalent functions have a "Shallow" prefix, which makes
it clear that they don't measure things hanging off the table. This patch makes
mozilla::Hash{Set,Map} do likewise.

This adds an '--allocation-filter' param that can be used to limit output to
only allocations that include the filter in their stack. For example:
dmd.py --allocation-filter fontconfig dmd.json.gz
limits its output to just allocations that have an instance of 'fontconfig' in
in one of their stack frames.

Bug 1364359 is to fix a leaked arena. Until that is fixed; it is unsafe to
call moz_dispose_arena more than once.

This behavior matches what gets used in mozalloc.h to define these
wrappers, and is particularly necessary for newer versions of clang to
not complain about our definitions.
That NDK bug has been fixed since r8c, and we now require something more
recent than that. This effectively reverts the changes from bug 720621
and bug 734832.

Base allocator commit stats were added in bug 515556, along other commit
stats, but they have actually been wrong since then: the committed count
is updated with the difference between pbase_next_addr and
base_next_decommitted *after* the latter is set to the former, making
the difference always 0.

Since TreeNode::{Left,Right,Color} is always a valid call to make, we
don't need to check if for nullity before calling those functions.
This effectively kind of reverts some parts of bug 1412722.

The code before bug 1412722 benefitted from the sentinel being an actual
node object, and some code paths ended up checking its color (always
black) or getting its right and left node, that always returned to the
sentinel.
When TreeNode currently contains a nullptr, all those lead to a null
deref if the calling code is not doing the right checks, which happens
to be the case in at least some places. Instead of relying on the
callers doing the right thing, make the TreeNode do the right thing when
it contains a nullptr, effectively acting as the sentinel in that case.
We additionally ensure that nothing in the calling code will be trying
to change the color or left/right pointers on the sentinel, which is an
extra safe net compared to the code before bug 1412722.

- Turn MOZ_DIAGNOSTIC_ASSERTs related to double-frees into
MOZ_RELEASE_ASSERTs with a crash message making them more identifiable
than the asserted condition.
- In huge_dalloc, MOZ_RELEASE_ASSERT early, instead of letting
RedBlackTree::Remove end up crashing because the node is not in the
tree.

Before bug 1412722, which removed the sentinels, the code looked like:
if (rbp_r_c->Right()->Left()->IsBlack()) {
At that point in the code, rbp_r_c is the root node of the tree. If
rbp_r_c->Right() was the sentinel, ->Right()->Left() would be the
sentinel too, and the sentinel is black. Which means the condition would
be true.
The code after was:
if (rbp_r_c->Right() && (!rbp_r_c->Right()->Left() ||
rbp_r_c->Right()->Left()->IsBlack())) {
The second half correctly deals with the case of
rbp_r_c->Right()->Left() being the sentinel. But the first half now
makes things different: ->Right() being null would correspond to the
previous case where it was the sentinel, and the test would not return
true in that case when it would have before. When ->Right() is not null,
things are normal again.
The correct check is to make the branch taken when ->Right() is null.
Now, looking under which conditions we may get in that branch wrongly:
- The root node's right link must be empty, which means a very small tree.
- The comparison between the removed key and the root node must indicate
the key is greater than the value of the root node.
- There's another case where the comparison result (rbp_r_cmp) can be
eGreater, when it is reassigned under one of the branches under the
eEqual test, and that branch is only taken when ->Right() on the root
node was non-null, which was the non-broken case.
So it would seem we can't reach that code when rbp_r_c->Right() is null
anyways, so it /should/ practically make no difference. Better safe than
sorry, though. It's hard to tell anything from crash stats, because
since the templatization in bug 1403444, all crashes fit in one bucket,
when there used to be 5 functions before :(
While here, add a missing include in rb.h.
