da60b99a88 ppc: Restrict some Altivec implementations to Big Endian
In Little Endian the vec_ld/vec_st operations work as
expected only for byte-vectors.

a053dbfcfb ppc: Move AltiVec utility headers out of AltiVec ifdefs
Now that the headers themselves have ifdef protection this is no
longer necessary and more consistent with normal include handling.

015821229f vp3: Use full transpose for all IDCTs
This way, the special IDCT permutations are no longer needed. This
is similar to how H264 does it, and removes the dsputil dependency
imposed by the scantable code.

Also remove the unused type == 0 cases from the plain C version
of the idct.

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

aeaf268e52 vp3: integrate clear_blocks with idct of previous block.
This is identical to what e.g. vp8 does, and prevents the function call
overhead (plus dependency on dsputil for this particular function).

Arm asm updated by Janne Grunau <janne-libav@jannau.net>.

28f9ab7029 vp3: move idct and loop filter pointers to new vp3dsp context
This moves all VP3-specific function pointers from dsputil to a
new vp3dsp context.  There is no reason to ever use the VP3 IDCT
where an MPEG2 IDCT is expected or vice versa.

98db4e2a4e PPC: Move types_altivec.h and util_altivec.h from libavcodec to libavutil
This will allow for easier implementation of Altivec functions in libraries
other than libavcodec.
