  rtmppkt: Check for packet size mismatches
  
  When receiving fragmented packets, the first packet declares the size,
  and the later ones normally are small follow-on packets that don't repeat
  the size and the other header fields. But technically, the later fragments
  also can have a full header, declaring a different size than the previous
  packet.
  
  If the follow-on packet declares a larger size than the initial one, we
  could end up writing outside of the allocation.
  
  This fixes out of bounds writes.

  configure: Pass CFLAGS_HEADERS through the right CFLAGS filter
  
  The generic parameter names used for CFLAGS in configure must be filtered
  for each compiler and replaced by the equivalent flag for that compiler.
