Also make sure that we only exit or restart the video if it is not paused and
if the picture queue is empty.

There is still room for improvement (filters may also buffer some frames), but
the patch fixes the most common use cases and ticket #2783 as well.

When libavformat was changed to use the new avpriv_open function
in 51eb213d, this silently bypassed the existing wrapper for
win32. Move the win32 wrapper into libavutil/file.c to make sure
it gets called everywhere (not just in the libavformat case).

This makes sure that non-ascii file names gets opened properly
(where file names internally are stored as utf8, but they get
converted to wchar_t and opened with _wsopen).

Such buffers are not malloced thus freeing would be bad.
Note though this condition never could have happened so this
is more for correctness sake and not a true bugfix

This performs the start code search which was previously part of
h264_find_frame_end() - the most CPU intensive part of the function.

By itself, this results in a performance regression:

but this can more than be made up for by platform-optimised
implementations of the function.

Each AVStream struct for an H.264 elementary stream actually has two
copies of the H264DSPContext struct (and in fact all the other members
of H264Context as well):

((H264Context *) ((AVStream *)st)->codec->priv_data)->h264dsp
((H264Context *) ((AVStream *)st)->parser->priv_data)->h264dsp

but only the first of these was actually being initialised. This
prevented the addition of platform-specific implementations of
parser-related functions.
