Add link to official specifications, remove author duplication and
others.

Remove one level of indirection, simplify code.

Remove one level of indirection/improve readability.

Also rename variable "extradata" to "palette" ff_cmap_read_palette()
and extract_header(), more meaningful.

Remove the problematic av_dlog() call

Added oggpagesize option for Ogg encoding. Allows setting a preferred page size. When set, if an Ogg stream buffer has enough data, a page is made, instead of filling maximum-size pages.

This for example fixes -t with some frext h264 reference streams.

This fixes some overflow in bright areas and ensures that the maximum brightness level is
mapped to the maximum without cliping and without showing dither patterens in flat max
brightness areas.

This is done by just letting the Nbit code handle it, which now can do it.

With this change libavutil uses av_freep() everywhere where it makes sense.
Remaining av_free() use in it has the used pointer become inaccessible quickly
soo zeroing makes no sense.

This is consistent with how all the other options work.

The low quality mode is off by default and never tested.  The high
quality mode is also plenty fast enough.

Earlier, AVIO_RDWR was handled as READ, and all the checks
for the AVIO_WRONLY flag explicitly meant the write-only case.
When changed from old AVIO/URL contants to AVIO_FLAG in
59d96941, these comparisons were updated incorrectly, by
mapping checks for AVIO_WRONLY to checks for AVIO_FLAG_WRITE.

When receiving RTP over UDP, the urlcontext is opened with
READ_WRITE flags.

This patch updates the flag comparisons to check for the same
conditions as the code did prior to 59d96941.

This fake option cannot be enabled by normal means, and the

This separates encoding and decoding flags, and passes them together
with the related file argument instead of all at the start of the
