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.

b695256edd configure: fix --cpu=host with gcc 4.6 
The output from -v with gcc 4.6 has changed such that the search
pattern matches too soon without making it more strict.

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
allocation error on my system.

8bfd7f6a47 alsa: fallback to buffer_size/4 for period_size. 
buffer_size/4 is the value used by aplay. This fixes output to null
devices, e.g. writing ALSA output to a file.

99fecc64b0 gxf: Fix 25 fps DV material in GXF being misdetected as 50 fps 
Set DV packet durations using fields_per_frame.
This requires turning gxf_stream_info into the demuxer's context for access to the value in gxf_packet().
Since MPEG-2 seems to work fine this done only for DV.

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.
