build: remove unnecessary FFLDFLAGS variable

This variable is set to the same value for all directories.
Adding the -L flags directly to LDFLAGS is simpler and achieves
the same thing.

Eliminate FF_COMMON_FRAME macro.

to struct Picture. Replace by an embedded AVFrame structure in struct Picture.

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.

This reduces startup latency for make invocations, which is especially
noticeable on systems that are slow or have slow I/O, like Windows.

prerequisites and link against the libs they need.

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.

Since MPEG-2 seems to work fine this done only for DV.

one bit of precision fixes this.
