70d80ed40f qdm2: Allow hard-coding VLC tables. 
Also adds a lot of infrastructure necessary for it.
Some of it is a bit ugly though.
Increases binary size for hardcoded tables by about 12 kB,
which is about 15 kB from qdm2_table minus data and code
saved that was only used for creating it.

16c7a8a142 aacps: invert the order of parameters of ipdopd_reset() 
This is the order that the caller uses in the rest of the file. The
same operation is applied to both parameters, so this change is only
done for consistency, it doesn't change the actual behaviour.

91bfac759d h261enc: Disallow sliced encoding 
This avoids trying to do sliced encoding, even if a slice/packet
size is requested (via the -ps option or the rtp_payload_size
field), since the encoder currently doesn't support it (or at least
our decoder can't decode it, even if the h261_encode_gob_header
function is hooked up to be called from the slicing part in
mpegvideo_enc.c).

The available sample decodes correctly before, but the reporter of the bug
claims that this change reduces artifacts. This is thus merged
If someone has samples that decode differently depending in the MAX_SLICES
value, please open a ticket on trac.
Also this change should be reverted if it turns out that the artifacts
that where seen had a different cause

Don't include the function pointer table in the code segment

This shouldn't have any significant performance effect. It does
end up as a few more instructions than before, for ARM, but
only at the entry to this function, not within the fft functions
themselves.

0f6931f4b6 avcodec/pngdec: use memcpy instead of byte loops for P frames. 
Rely on the way memcpy is optimized for one's system instead of looping
on a byte buffer for buffer copies to handle P frames.

9fa056ba75 pngdsp x86: use unaligned access 
For test images manually generated to contain only up prediction,
timing results:
         8380x3032    255x185
before:   138635       1992
after:    139232       1996

Actually jumping to the proper version depending on the alignment:
8380x3032: 138767

A 0.5% speed improvement for gigantic images is not worth the code
duplication.
