  configure: Use indirection for the -o assembler flag also for x86asm
  
  Similar indirections are used for the -o compiler/assembler flag to
  account for differences in compiler/assembler syntax. For x86asm half
  the infrastructure for doing the same currently exists unused.
  Finish and use that infrastructure for consistency.

• configure : Don’t assume an aligned stack on clang on windows

  12 mars 2018, par Martin Storsjö

  configure: Don't assume an aligned stack on clang on windows
  
  If we'd enable a 16 byte aligned stack, clang/llvm would also assume
  that alignment everywhere and produce code that strictly requires it.
  That would require adding realignment (via attribute_align_arg) on every
  single public library function or enable -mstackrealign (which does the
  same on every single function).
  
  Also relatedly; the parameter currently tested (-mllvm
  -stack-alignment=16) hasn't actually been supported for quite some
  time; current clang versions use -mstack-alignment=16 for the same.
  Actually testing for that parameter would be a different change
  though, since it has a real risk of changing behaviour on any other
  platform where clang is used.

  avcodec/extract_extradata: Move the reference in the bsf internal buffer
  
  There is no need to allocate a new packet for it.

  avcodec/extract_extradata: don't uninitialize the H2645Packet on every processed packet
  
  Based on hevc_parser code. This prevents repeated unnecessary allocations
  and frees on every packet processed by the bsf.
