4e5d2a819c avcodec/internal: Remove outdated documentation of ff_alloc_packet2()
Its documentation described the way user-supplied buffers worked
before 93016f5d1d.

Also combine two if blocks that check for the same condition
and don't check had_partial if we already have a complete packet.

eeedc8817a avcodec/omx: Remove remnants of old preallocated buffers
There are no preallocated buffer packets any more; this feature only
worked with the old encode API and only until said API was turned into
a wrapper for the new API in 93016f5d1d.
So remove its remnants.

835d8b7401 avcodec/dvenc: Avoid copying packet data, allow user-supplied buffers
When the packet size is known in advance like here, one can avoid
an intermediate buffer for the packet data; this also makes it easy
to allow user-supplied buffers. Only one thing needed to be changed:
The earlier code relied on the buffer having been initially zeroed
by av_fast_padded_malloc(), so one now needs to zero the packet at
first.

282b9f4cba avfilter/overlay_cuda: add hsub and vsub compute x and y positions
fix problem when set x to odd number in nv12 by cuda

test step:
1. ffmpeg -f lavfi testsrc2=s=176x144 -pix_fmt nv12 -t 1 output_overlay.yuv
2. ffmpeg -f lavfi testsrc2=s=352x288 -pix_fmt nv12 -t 1 output_main.yuv
before this patch:
overlay_cuda=x=0:y=0 will right,
overlay_cuda=x=3:y=0 will wrong,

both will right after patch.

8bcce5673a avcodec/nvenc: add option to disable all extra SEI data
With these triggering a lot of crashes recently, an option to globally
disable all of them is added as a tool to work around those crashes in
case the SEI data is not needed by the user.

Also re-enables s12m for hevc_nvenc, since the issue is not specifically
with that, but it affects all SEI data.

6b1268f8c3 pixfmt: fixed wrong fix of comment
This mostly reverts 785bfb1d7b.
But I also added some clarifications so that nobody mixes primaries
with matrix again. SMPTE 240 and 170 primaires are the same, while
matrix coeff. are different, because 240 is derived from 170's new
primaries and white point while 170 uses BT.601 derived from BT.470
System M (yes, with Illuminant C) a.k.a. NTSC 1953. Some nits too.
