cd86eb265f avcodec/x86/videodsp: fix a bug in a %if statement where we used '%%' instead of '&&'.

41efb8d9a7 avcodec/x86/cabac: include get_cabac_bypass_sign_x86() under #if !BROKEN_COMPILER 
this might fix Ticket2999 as well as some fate clients
untested as the original patch submitter no longer has the environment to test
this should be reverted if it does not fix the issues

1b3a7e1f42 avcodec/x86/videodsp: Properly mark sse2 instructions in emulated_edge_mc x86 simd as such. 
Should fix crashes or corrupt output on pre-SSE2 CPUs when they were
using SSE2-code (e.g. AMD Athlon XP 2400+ or Intel Pentium III) in
hfix or hvar single-edge (left/right) extension functions.

bbe4a6db44 x86inc: Utilize the shadow space on 64-bit Windows 
Store XMM6 and XMM7 in the shadow space in functions that
clobbers them. This way we don't have to adjust the stack
pointer as often, reducing the number of instructions as
well as code size.

face578d56 Rewrite emu_edge functions to have separate src/dst_stride arguments. 
This allows supporting files for which the image stride is smaller than
the max. block size + number of subpel mc taps, e.g. a 64x64 VP9 file
or a 16x16 VP8 file with -fflags +emu_edge.

2ffead98dd avcodec: add emuedge_linesize_type 
Currently all uses of the emu edge code as well as the code itself

changing some but not changing all would introduce a security issue
once all use this typedef a simple search and replace can be
done to switch them all to ptrdiff_t
