We need to call CoInitialize, so we need to include the objbase.h header. That defines some generic boolean stuff, which conflicts with something that libjpeg defines. I tried working around it, but I gave up, this solution seems fine.

Beyond the necessary reinitialization methods, we need to protect
ourselves from recycling a frame that some other entity in the browser
is still using. Generally speaking the animated surface will only be
used in imgFrame::Draw since we don't layerize animated images, which
will be safe. However with OMTP or blob recordings, we could retain a
reference to the surface outside the current stack context. Additional
if something calls RasterImage::GetImageContainer(AtSize) or
RasterImage::GetFrame(AtSize), it may also have a reference to the
surface for an indetermine period of time.
As such, if an imgFrame is a candidate for recycling, it will wrap
imgFrame::mLockedSurface in a RecyclingSourceSurface. Its job is to
track how many consumers there are still of the surface, so that after
we advance the animation, the decoder will know if there are still
outstanding consumers.
If the surface is still in use, it will block for a finite period of
time (the refresh interval) before giving up on reclaiming the surface,
and will allocate a new surface. The old surface can then remain in
circulation for as long as necessary without further blocking the
animation progression, since we stop recycling that surface/imgFrame.

By delegating responsibility for shared surfaces reporting to imagelib,
we can cross reference the GPU shared surfaces cache with the local
surface cache in a content process (or the main process). This will
allow us to identify entries that are in the GPU cache but not in the
content/main process cache, and aid in debugging memory leaks. This
functionality is pref'd off by default behind image.mem.debug-reporting.
Additionally, we want to report every entry that was mapped into the
compositor process, in the compositor process memory report. This will
give us a sense of how much of our resident memory is consumed by mapped
images in absence of the more detailed cross referencing above.

This removes the unnecessary setting of c-basic-offset from all
python-mode files.
This was automatically generated using
perl -pi -e 's/; *c-basic-offset: *[0-9]+//'
... on the affected files.
The bulk of these files are moz.build files but there a few others as
well.
