The 'edts' write function can now generate an initial empty edit resulting in a track-specific presentation delay.
This is automatically calculated and inserted for any track where the initial DTS != 0.
Added support for long (version==1) timecodes.

This merges the float and fixed-point versions of the compute_antialias
function, fixes invalid array indexing, and eliminates a dead copy of
csa_table.

Fixes compilation on PPC with Altivec enabled.

Since we want to break the loop the 'if (data_ofs < 0)' block is moved after the loop.
This fixes ticket #250.

Improve consistency.

Replace opt_{audio,video,subtitle,data}_codec() with a single
opt_codec() function.

Simplify/clarify the code logic and error reporting.

Use av_get_pix_fmt_name() instead.

This enables UAL syntax for all asm files instead of only those
which happen to be incompatible with the old, deprecated syntax.

Avoids a large amount of warnings about cast discarding qualifiers.
