3aa0be003e avcodec/iirfilter: Fix memleak
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.

ea1b71e82f avcodec/hevc_mp4toannexb_bsf: Check NAL size against available input
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.

318a1a383d avcodec/cbs_av1: abort when written inferred values don't match
If this happens, it's a sign of parsing issues earlier in the process, or
misuse by the calling module.

Prevents writing invalid bitstreams.
