aa2ead8215 Fix mis-computation of the needsDither variable erroneously introduced 
in r30419, which was causing a swscale-example regression.

Also increase my liter count by 20.0 units.

996b099a0f Branchless setting of MB_TYPE_8x8DCT. 
Not benchmarked as i failed to find a sample that uses this one. But it should be faster.

d9ef0d2e14 Mark index as unsigend so gcc knows it doesnt need a sign extension on x86_64. 
Any tips on how i can convince gcc that it doesnt need a
mov     %eax, %eax
in every get_bits() ?

f1d2b5728c Make url_read_complete handle EAGAIN more intelligently. 
Only retry 2 - 5 times in quick succession and afterwards sleep a bit
to avoid creating high CPU load without any progress.

0b882b4009 Fix crash in MLP decoder due to integer overflow. 
Probably only DoS, init_get_bits sets buffer to NULL, thus causing a
NULL-dereference directly after.
