15ef16dce8 avcodec/g723_1enc: Avoid skip_put_bits()
If a bit is reserved, it matters very much what value it has, because
otherwise a decoder conforming to a future version of the standard might
interpret the output file in an unintended manner. This implies that
one must not use skip_put_bits() for it (which does not give any
guarantees wrt what ends up in the output (in case of a little-endian
bitstream writer (as here) it writes a 0 bit)); given that the reference
encoder as well as the earlier code write a zero bit at this place, the
new code does, too.

6ceaeecaf5 avcodec/libsvt_av1: remove forced-idr option
This option is directly copy-pasted from the SVT1-HEVC wrapper and has
no place in the options for an AV1 encoder.

AV1 has no H.264/5 IDR frames nor anything like them.
All this option does is change all real keyframes to an intra-only
AV1 frame, which is not seekable. Hence, any streams encoded with
this option enabled will not be seekable.

instead of get_ue_golomb(). The difference between the two is that the
latter also has to take into account the case in which the read code is
more than 9 bits (four preceding zeroes + at most five value bits) long,
leading to more code.

2d5407d390 avcodec/golomb: Document return value of get_ue_golomb_31 on error
get_ue_golomb_31() reads nine bits and an array with 512 entries to
parse golomb codes. The longest golomb codes that fit into 9 bits use
four leading zeroes and five value bits and can encode numbers in the
0..30 range. 31 meanwhile is encoded on 11 bits and if the nine bits
read coincide with the first nine bits of the encoding of 31,
get_ue_golomb_31() returns 31 (and skips 11 bits).

But looking at the first nine bits only makes it impossible to distinguish
31 from 32..34. Therefore the documentation of get_ue_golomb_31() simply
states that the return value is undefined if the value of the encountered
exp golomb code was outside the 0..31 range.

But actually get_ue_golomb_31() does not behave that bad: If the returned
value is in the range of 0..30, then this is the actually encountered value,
so that this function can be used without any problems to parse and validate
parameters whose legal values are a subset of the 0..30 range.

This commit documents this fact.

69636b443c avcodec/golomb: Prevent shift by negative number
This happened in get_ue_golomb() if the cached bitstream reader was in
use, because there was no check to handle the case of the read value
not being in the supported range.
For consistency with the uncached bitstream reader and for compliance
with the documentation, every value not in the 0-8190 range is treated as
error although the cached bitstream reader could actually read values in
the range 0..65534 without problems.

This reverts commit 489c5db0791f39518775b12eef6d48276c17f96f.

Treating EQUAL_MULTI_ROWS in the same way as the arbitrary-size cases is
just wrong.  Consider 9 rows, 4 slices - we pick 4 slices with sizes
{ 3, 2, 2, 2 }, which EQUAL_MULTI_ROWS does not allow.  It isn't possible
to split the frame into 4 slices at all with the EQUAL_MULTI_ROWS
structure - the closest options are 3 slices with sizes { 3, 3, 3 } or 5
slices with sizes { 2, 2, 2, 2, 1 }.
