  ff_get_format: fix infinite loop
Merged-by: Michael Niedermayer <michaelni@gmx.at>

This avoids warnings about using the codec time base as time
base hint.
Signed-off-by: Martin Storsjö <martin@martin.st>

By using ff_avc_write_annexb_extradata instead of the h264_mp4toannexb
BSF, the code for doing the conversion itself is kept much shorter,
there's less state to restore at the end, we don't risk leaving the
AVCodecContext in an inconsistent state if returning early due to
errors, etc.

Also add a missing free if the base64 encoding fails.

The register function now specifies that the user callback should
leave things in the same state that it found them on failure but
that failure to destroy is ignored by the library.  The register
function is now explicit about its behavior on failure
(it unregisters the previous callback and destroys all mutex).

This function provides an explicit VDPAU device and VDPAU driver to
libavcodec, so that the application is relieved from codec specifics
and VdpDevice life cycle management.

A stub flags parameter is added for future extension. For instance, it
could be used to ignore codec level capabilities (if someone feels
dangerous).

This is necessary to recreate the decoder with the correct parameters,
as not all codecs invoke get_format() in this case.

Fixes regression from Ticket3962

This basically favors the first global header while since 34751f83
it was the last. If this heuristic turns out worse, do not hesitate to revert this and
reopen 3962 as a feature request for multiple STSD
