We assume that if we have 30s of data buffered ahead of the current position or up to the element's duration that we can play ahead without interruption.
We require a slightly variation on the default implementation as mediasource allows for gaps of up to 125ms between samples and often videos do not start with a time of 0.
In this process, TransformTo() and UntransformTo() are renamed TransformedBy()
and UntransformBy() so calls to them continue to read sensibly.

Call sites (all in APZ and related code) were modified accordingly. Some of
these modifications involved changing some matrices stored in APZ to be typed.

Matrix4x4 remains a typedef for Matrix4x4Typed<UnknownUnits, UnknownUnits>.
No client code needed changing, except for forward-declarations of Matrix4x4
as a class (since it's now a typedef).

When I modified ehsan's patch in bug 904572 to switch to a build backend
instead of a mach command, I forgot to remove the line added to
mach_bootstrap.py to pick the mach command, which now doesn't exist.
Sccache was enabled mechanically by the switch to EC2 Windows instances, while
it is not intended to be used on PGO builds.
This happened because the fix for bug 1181040 disabled sccache for PGO builds
where MOZ_PGO is set through mozconfig (in which case MOZ_PGO_IS_SET is set)
*while* ignoring the case where MOZ_PGO is set through the environment (in
which case MOZ_PGO_IS_SET is, unconveniently, *not* set). The latter is what
Windows PGO builds do.
The only use of BRANDING_FILES[...].source is in xulrunner/app/moz.build, for
the app.ico file.
This file has not been useful since the removal of the xpinstall-based
installer in bug 344236... 9 years ago.
Even when the segment feature data is in absolute mode, it is still read as a
6-bit value with an added sign, so it could have values between -63 and +63.
Later, this signed value is used without checks as a filter level, which is
used to access an entry in an array of size MAX_LOOP_FILTER+1=64.
This patch just extends the existing clamping (that was done only to relative-
mode data) to absolute mode data, before it is blindly 'memset' in
lfi->lvl[seg][0], which was where the out-of-bound filter_value was read in
subsequent vp8_loop_filter_row_simple.
To avoid potential regression with some of our tests expecting our old particular behaviour, we only use the buffered range to determine the next frame status if the old method determined that the next frame was unavailable due to the MediaDecodeStateMachine not having decoded the next frame yet.
When MediaDecoder::NotifyDataArrived is called, the buffered range hasn't been updated as of yet, causing unnecessary calls to UpdateReadyState().
Delay the readyState update until the buffered range is modified.
