Separate format conversion DSP functions from DSPContext.

This will be beneficial for use with the audio conversion API without
requiring it to depend on all of dsputil.

Fix ff_imdct_calc_sse() on gcc-4.6

Gcc 4.6 only preserves the first value when using an array with an "m"
constraint.

Implement a SIMD version of emulated_edge_mc() for x86.

From ~550 cycles (C version) to 170 (SSE/x86-64), 206 (MMX/x86-32)
and 196 (SSE2/x86-32) cycles.
