4cc3467e7a oggdec: prevent heap corruption. 
Specifically crafted samples can reinit ogg->streams[] while
reading samples, and thus we should not cache old pointers since
these may no longer be valid.

ca9036155d build: remove unnecessary FFLDFLAGS variable

Adding the -L flags directly to LDFLAGS is simpler and achieves

657ccb5ac7 Eliminate FF_COMMON_FRAME macro.

142e76f105 swscale: fix crash with dithering due incorrect offset calculation. 
ptrdiff_t can be 4 bytes, which leads to the next element being 4-byte
aligned and thus at a different offset than intended. Forcing 8-byte
alignment forces equal offset of dither16/32 on x86-32 and x86-64.

710b8df949 dsputil: remove ff_emulated_edge_mc macro used in one place 
This macro can cause problems in conjunction with the bitdepth
template expansion.  It was presumably added to keep source
compatibility when high bitdepth support was added.  However,
emulated_edge_mc is a dsputil pointer and should not be called
directly, so there is little reason to keep such a macro.
