6308729e68 ARM: check for inline asm 'y' operand modifier support 
The inline asm added in bf5d46d uses the 'y' modifier which
is only supported from gcc 4.5.  This check allows building
with older compilers.

6326afd5e9 avcodec: reject audio packets with NULL data and non-zero size 
There is no valid reason the user should ever send such packets in the
first place, but the documentation for CODEC_CAP_DELAY states that the
codec is guaranteed not to get a NULL packet unless that capability is
set. That isn't true without preventing this case.

dcce09d64b dxva: Add ability to enable workaround for older ATI cards 
The workaround needs to be enabled per PCI ID which cannot be detected inside
libavcodec. So add a flag to manually enable the alternate behavior.
