HEVC standard supports multi-layer streams (ITU-T H.265 02/2018 Annex F). Each NAL unit belongs to a particular layer defined by nuh_layer_id in the header. Currently, all NAL units that do not belong to a base layer are automatically removed in ff_h2645_packet_split(). Some data may therefore be lost when future filters/decoders are designed to support multi-layer streams. A better approach is to forward nuh_layer_id > 0 packets and let blocks down the chain decide how to process them. The condition to remove packets has been moved to hevcdec and cbs.

This will likely also fix CID 1452427, a false positive resulting from Coverity thinking that av_dict_set() automatically frees its key and value parameters (even without the AV_DICT_DONT_STRDUP_* flags). (AV_DICT_APPEND and AV_DICT_DONT_STRDUP_VAL are compatible with each other since a8c5b455, so we can reset this flag here. It has originally been removed in 0dc66553 when appending was added.)

libx265.c references a member x265_picture.quantOffsets (for ROI support) which was added in X265_BUILD 70. Increase the minimum libx265 version to fix compilation.

When shifting the already written data in order to write the keyframe index, the flv muxer would first store the pre-shift size, then calculate how big the index will be eventually, then perform some seeks to update some size fields, then seek back to the end of the file to get the new position, followed by a seek to the position where writing will really start. Seeking back to the (already known) end position (that is actually used to perform this seek) to get the end position is of course unnecessary. It has been removed.

When the faststart option for the mov/mp4 muxer is used, the current position (i.e. the size of the already written data pre-shifting) was evaluated twice: First in an initialization and then again later, overwriting the first value without having ever touched it. So remove the initialization. Also, the clone of this code in the Sega FILM muxer behaves the same and has been treated the same.
