25841dfe80 Use ptrdiff_t instead of int for {avg, put}_pixels line_size parameter. 
This avoids SIMD-optimized functions having to sign-extend their
line size argument manually to be able to do pointer arithmetic.

88bd7fdc82 Drop DCTELEM typedef 
It does not help as an abstraction and adds dsputil dependencies.

42d3246948 floatdsp: move vector_fmul_reverse from dsputil to avfloatdsp. 
Now, nellymoserenc and aacenc no longer depends on dsputil. Independent
of this patch, wmaprodec also does not depend on dsputil, so I removed
it from there also.

d526c5338d ARM: allow runtime masking of CPU features 
This allows masking CPU features with the -cpuflags avconv option
which is useful for testing different optimisations without rebuilding.

2bcbd98459 Remove lowres video decoding 
This feature is complex, of questionable utility, and slows down
normal decoding.

363bd1c62c remove iwmmxt optimizations 
The were broken since August of 2010 without anyone noticing until
three weeks ago. Nobody cares about it anymore and hopefully Marvell
will support NEON like in the PXA978 from now on.

19a0729b4c Adds 8-, 9- and 10-bit versions of some of the functions used by the h264 decoder. 
This patch lets e.g. dsputil_init chose dsp functions with respect to
the bit depth to decode. The naming scheme of bit depth dependent
functions is <base name>_<bit depth>[_<prefix>] (i.e. the old
clear_blocks_c is now named clear_blocks_8_c).

Note: Some of the functions for high bit depth is not dependent on the
bit depth, but only on the pixel size. This leaves some room for
optimizing binary size.

Preparatory patch for high bit depth h264 decoding support.
