absent (if the pointer has been supplied).

Commits 957a593cd9 and
11828b8885 made the flv demuxer export
a certain flag as side data to be used by the nellymoser decoder for
mid-stream sample rate changes. It used a custom side data type 'F' that
was never officially documented.
Yet since 2215c39e94 (merged in commit
52c522c720) this information is exported
via the properly documented AV_PKT_DATA_PARAM_CHANGE side data.
The merge commit therefore stopped exporting the 'F' sidedata; yet the
changes in the Nellymoser decoder (which are now dead code (and would
become dangerous if lots of new side data types were added)) have not
been removed. This commit does this.

Fixes an issue with one output channel being slightly louder than
the other. The output now matches other public HCA decoders.

I suspect this was originally broken by b7e5c8f , but even
then, it only worked because it read out of bounds from
intensity_ratio_table.

Following the same logic as 061a0c14bb, this commit turns the old encode API
into a wrapper for the new one.
Signed-off-by: James Almer <jamrial@gmail.com>
This commit follows the same logic as 061a0c14bb, but for the encode API: The
new public encoding API will no longer be a wrapper around the old deprecated
one, and the internal API used by the encoders now consists of a single
receive_packet() callback that pulls frames as required.

Commit 17e88bf0df created a memleak by
removing a call to ff_iir_filter_free_coeffsp on error; this has been
found by Coverity (ID 1464159). This commit fixes the memleak by
readding the call to ff_iir_filter_free_coeffsp.
Notice that this is not a simple revert, because several macros that
were used before 17e88bf0df were replaced
in commit 44863b2c2d and completely removed
in 2658680df4.

The hevc_mp4toannexb bsf does not explicitly check whether a NAL unit
is so big that it extends beyond the end of the input packet; it does so
only implicitly by using the checked version of the bytestream2 API.
But this has downsides compared to real checks: It can lead to huge
allocations (up to 2GiB) even when the input packet is just a few bytes.
And furthermore it leads to uninitialized data being output.
So add a check to error out early if it happens.
Also check directly whether there is enough data for the length field.

If this happens, it's a sign of parsing issues earlier in the process, or
misuse by the calling module.
