The texture client bound in a GPUVideoImage can be destroyed underneath
it if the GPU process crashed and was restarted. This is because the
ImageBridgeChild singleton will destroy any textures bound to it before
reinitializing itself. If there is a race to access a now stale
GPUVideoImage object, we could accidently dereference the underlying
TextureData which is now null in the TextureClient which was kept alive
in the GPUVideoImage object. Now we check to make sure the TextureData
is still there before accessing.
Additionally, various C++ code and style cleanup

This patch was generated automatically by the "modeline.py" script, available
here: https://github.com/amccreight/moz-source-tools/blob/master/modeline.py
For every file that is modified in this patch, the changes are as follows:
(1) The patch changes the file to use the exact C++ mode lines from the
Mozilla coding style guide, available here:
https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Coding_Style#Mode_Line
(2) The patch deletes any blank lines between the mode line & the MPL
boilerplate comment.
(3) If the file previously had the mode lines and MPL boilerplate in a
single contiguous C++ comment, then the patch splits them into
separate C++ comments, to match the boilerplate in the coding style.
