MJPEG Tools Svn

remove unnecessary (and invalid, with some vers of gcc) parens around datatype:
new (Picture *)[x] ::= new Picture *[x]

delete (unused and inefficient) quant_weight_coeff_sum_mmx_old

Add sse version of fdct based on daan (more accurate, but 50% slower)

lavplay works correctly now with the latest libquicktime.

add reference fdct implementation
fix rounding bug in basic C/integer fdct implementation
add fdct_test
rename fdctref.c -> fdct.c for consistency with idct*.c

Separate out testing code into new func

fix -M 0 (don't initialize Despatcher if parallelism==0)

Needed a debug point for a problem - but the new code's a bit cleaner too.

improved mmx idct (faster and more accurate), add sse idct (slower but very accurate)

better quant_weight_coeff_sum_mmx -- explicit parallelism, better abs func
