When there are potentially annotation (i.e. metadata) fields to write,
au_get_annotations() is called to produce a string with them. To do so,
it uses an AVBPrint which is finalized to create the string. This is
wasteful, because it always leads to an allocation even if the string
actually fits into the internal buffer of the AVBPrint. This commit
changes this by making au_get_annotations() modify an AVBPrint that
resides on the stack of the caller (i.e. of au_write_header()).
Furthermore, the AVBPrint is now checked for truncation; limiting
the allocations implicit in the AVBPrint allowed to offload the overflow
checks. Notice that these were not correct before: The size parameter of
avio_write() is an int, yet the string in the AVBPrint was allowed to
grow bigger than INT_MAX. And if the length of the string was so near
UINT_MAX that the length + 32 overflowed, the old code would write the
first eight bytes of the string and nothing more, leading to an invalid
file.
Finally, the special case in which the metadata dictionary of the
AVFormatContext is empty (in which case one still has to write eight
binary zeroes) is now no longer treated specially, because this case
no longer incurs any allocation.

This av_freep(&key) in conjunction with the fact that the loop condition
checks for key != NULL was equivalent to a av_freep(&key) + a break
immediately thereafter. But given that there is an av_freep(&key)
directly after the loop, the av_freep(&key) is unnecessary and the break
can also be added explicitly.

RGB pixel formats are one occasion where by pixel format we mean
pixel format, primaries, transfer characteristic, and matrix coeffs,
so we have to manually set them as they're set to unspecified by
default, despite there only being a single possible combination.
The RPCL progression order check was incomplete. This
patch completes the check. Tested on p1_07.j2k.

v4l2_receive_frame() uses two packets s->buf_pkt and avpkt. If avpkt
cannot be enqueued, the packet is buffered in s->buf_pkt and enqueued in
the next call. Currently the ownership transfer between the two packets
is not properly handled. A double free occurs if
ff_v4l2_context_enqueue_packet() returns EAGAIN and v4l2_try_start
returns EINVAL.
In fact, having two AVPackets is not needed and everything can be
handled by s->buf_pkt.
This commit removes the local avpkt from v4l2_receive_frame(), meaning
that the ownership transfer doesn't need to be handled and the double
free is fixed.

Some legacy applications such as AVI2MVE expect raw RGB bitmaps
to be stored bottom-up, whereas our RIFF BITMAPINFOHEADER assumes
they are always stored top-down and thus write a negative value
for height. This can prevent reading of these files.
Option flipped_raw_rgb added to AVI and Matroska muxers
which will write positive value for height when enabled.
Note that the user has to flip the bitmaps beforehand using other
means such as the vflip filter.
Currently, the COC marker overrides the SOP marker bit.
However, only the COD marker may set this value. This
patch fixes this bug.

The number of declared vdpau formats can vary depending on which
version of libvdpau we build against, so the number of pix fmts
can vary too. Let's make sure we keep those numbers in sync.
Some new warnings regarding use of empty macro parameters has
been added, so adjust some x86inc code to silence those.
