Web standards use "Container" instead of "Parent". So, nsRange shouldn't use "Parent" for its members and methods.

Due to the fix of bug 1376424, ContentCacheInParent::FlushPendingNotifications() may be called when aWidget is nullptr. In this case, it doesn't need to do anything. So, it should ignore the call.

We're not really gaining much information by checking for an upper limit on
the bytesReceived or bytesSent stat here. This should help with
intermittent failures.

Makes initing Places services cheaper, by delaying the connection creation to the first time
it's actually needed.
Same way, delays reading the bookmark roots at the first time they are requested.
Deprecates the concept of lazy observers, since they are no more needed, we can just use addObserver.
Simplifies the startup path: always sends "places-init-complete" (both as a category and a topic) when
the connection starts and adds a "locked" database state when we can't get a working connection.
Makes PlacesCategoriesStarter register for the new category, since it's cheaper than being a bookmarks
observer.
Fixes a couple race conditions in keywords and expiration due to new startup timings.
Removes a test in test_keywords.js that is no more easily feasible, since it'd requires a pre-build
places.sqlite that should be kept up-to-date at every version.

Previously, we submitted polygons as a list of triangles, duplicating
some ancillary data with each vertex. As we move away from constant
buffers for some of this ancillary data, it will bloat the size of each
vertex. To avoid this, we will now instance over a unit triangle
instead. Each instance contains three triangle coordinates and ancillary
data can be shared between them. The target vertex is computed similarly
to how we handle rects in the unit quad shaders.
Since bug 1378258 remove malloc_print_stats, there are a bunch of
allocator stats that are now unused, reducing the memory footprint of
allocator metadata.

When initializing a new chunk for use as an arena, we started by zeroing
out the chunk (if that wasn't the case) and then initializing a new
arena chunk in there. It turns out this can have a noticeable overhead,
especially when e.g. the new arena chunk is used for a large allocation
filled out by something that is realloc()ated.
OTOH, the chunk recycle code only ever keeps zeroed or arena chunks
around (there is a "recycled" type too, but in practice, at the moment,
this means they were arena chunks before). Arena chunks that were
recycled were totally emptied, so all the runs they may contain will
contain zeroed-out or poisoned data. They also contain a header, that is
overwritten by the new arena chunk initialization.
This means we can get away with reusing non-zeroed recycled chunks
without zeroing them, as long as the arena chunk header marks the runs
as madvised instead of zeroed.
Code-wise, this would benefit from getting a ChunkType out of
chunk_alloc, but this would require more refactoring than I'm willing to
do at the moment.
Before returning a chunk, chunk_recycle calls pages_commit (when
MALLOC_DECOMMIT is enabled), which is guaranteed to zero the chunk.
The code further zeroing the chunk afterwards, which is now moved out to
chunk_alloc callers, never took advantage of that fact, duplicating the
effort of zeroing the chunk on Windows.
By indicating to the callers that the chunk has already been zeroed, we
allow callers to skip zeroing on their own.
The current code only allows chunk_calloc() callers to tell whether they
want zeroed memory or not, but some might be okay either way, assuming
they act accordingly afterwards. So move the zeroing out of chunk_alloc.
Many functions in the mozjemalloc codebase like to return the opposite
boolean one would tend to expect. Pages_purge is one of them, and this
reverses the logic to match expectations.
Also make it static.
It turns out that not recycling some kinds of chunk can lead to the
recycle queue being starved in some scenarios. When that happens, we end
up mmap()ing new memory, but that turns out to be significantly slower.
So instead of not recycling huge chunks, we force-clean them, before
madvising so that the pages can still be reclaimed in case of memory
pressure.

~AzureState is expensive, especially in GlyphBufferAzure::Flush, which is a high
