* avcodec/iirfilter: Fix memleakAndreas Rheinhardt2020-06-15
| | | | | | | | | | | | | | | Commit 17e88bf0df21906633a7d36d9f2aeeeb5b6d3267 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 17e88bf0df21906633a7d36d9f2aeeeb5b6d3267 were replaced in commit 44863b2c2d5a31d82aafa71cdbd180d6bfbed5b4 and completely removed in 2658680df4fc606522e5f65899afb9a98b47d287.

* avcodec/hevc_mp4toannexb_bsf: Check NAL size against available inputAndreas Rheinhardt2020-06-15
| | | | | | | | | | | | | | | 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.
