In addition to .eac3, .ec3 is also commonly used by people to name raw
E-AC-3 streams. Enables automatic recognition of the eac3 format for
the .ac3 extension.
For instance Dolby Digital Plus software only support files with
.ec3. Files with .eac3 are not supported. Check issue #18 in the
public dlb_mp4base repository from DolbyLaboratories.

It (unfortunately) involves an allocation and can therefore fail.

The functions to replace parameter sets are only called
after the respective parameter set has just been read or
has just been written; all of these functions check
that the id field is within the appropriate range.
So the checks in the replace-functions can be removed.

The code just creates new references without allocating
new buffers for the subobjects; therefore the actual data pointer
stays valid and need not be updated.
Also remove an assert that ensured that the calculation
for updating the pointer makes sense.

This updates the list closer to reality.
Iam not a professional server admin, iam happy to help maintain the box as i have
done in the past. But iam not qualified nor volunteering to fix sudden problems
nor do i do major upgrades (i lack the experience to recover the box remotely if
something goes wrong) and also iam not maintaining backups ATM (our backup system
had a RAID-5 failure, raz is working on setting a new one up)
Maybe this should be signaled in a different way than spliting the lines but ATM
people ping me if something is wrong and what i do is mainly mail/ping raz
and try to find another root admin so raz is not the only active & professional
admin on the team. It would be more efficient if people contact raz and others
directly instead of depending on my waking up and forwarding a "ffmpeg.org" is down note

It's not modified, so we can simply use a const pointer to it.
Also check the return value of the other copy in the function while at it.

nvenc does not appear to use these values as inputs for its built in RGB
to YUV conversion, but instead sets them on the output as-is.
Testing indicates the input is expected to be sRGB, with the output
ending up as limited range bt.470.
Up until now, there were four copies of
quantize_and_encode_band_cost_(ZERO|[SU]QUAD|[SU]PAIR|ESC|NONE|NOISE|STEREO)
(namely in aaccoder.o, aacenc_is.o, aacenc_ltp.o, aacenc_pred.o).
As 43b378a0d3 says, this is meant to
enable more optimizations.
Yet neither GCC nor Clang performed such optimizations: The functions
in the aforementioned files are not optimized according to
the specifics of the calls in the respective file. Therefore
duplicating them is a waste of space; this commit therefore stops doing
so. The remaining copy is placed into aaccoder.c (which is the only
place where the "round to zero" variant of quantize_and_encode_band()
is used, so that this can be completely internal to aaccoder.c).

Also constify the corresponding code in mpegvideo.c that handles
lowres.
(Unfortunately, not everything that is const could be constified:
ref_picture could be made const uint8_t* const* if C allowed the
safe automatic conversion from uint8_t**; and pix_op, qpix_op
could be made to point to const function pointers, but C's handling
of const in pointers to arrays is broken.)

__lasx_xvldx does not accept a pointer to const (in fact,
no function in lasxintrin.h does so), although it is not allowed
to modify the pointed-to buffer. Therefore this commit adds a wrapper
for it in order to constify the H264Chroma API in a later commit.
