657ccb5ac7 Eliminate FF_COMMON_FRAME macro.
FF_COMMON_FRAME holds the contents of the AVFrame structure and is also copied
to struct Picture.  Replace by an embedded AVFrame structure in struct Picture.

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.

3e5cce81e7 build: remove duplicates from order-only directory prerequisite list
This reduces startup latency for make invocations, which is especially
noticeable on systems that are slow or have slow I/O, like Windows.

28e1c97916 build: rework rules for things in the tools dir
Declaring tools associated with each library in their respective
makefiles allows these tools to easily depend on the correct
prerequisites and link against the libs they need.

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.

e35c674d13 alsa: limit buffer_size to 32768 frames.
In testing, the file output plugin gave a max buffer size of about 20 million
frames, which is way more than what is really needed and causes a memory

7d7bacf0f1 swscale: fix overflow in 16-bit vertical scaling.
We operated on 31-bits, but with e.g. lanczos scaling, values can
add up to beyond 0x80000000, thus leading to output of zeroes. Drop
one bit of precision fixes this.
