98fdfa9970 ppc: reduce overreads when loading 8 pixels in altivec dsp functions 
Altivec can only load naturally aligned vectors. To handle possibly
unaligned data a second vector is loaded from an offset of the original
location and the data is recovered through a vector permutation.
Overreads are minimal if the offset for second load points to the last
element of data. This is 7 for loading eight 8-bit pixels and overreads
are reduced from 16 bytes to 8 bytes if the pixels are 64-bit aligned.
For unaligned pixels the overread is reduced from 23 bytes to 15 bytes
in the worst case.

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.

fef906c77c Move vorbis_inverse_coupling from dsputil to vorbisdspcontext. 
Conveniently (together with Justin's earlier patches), this makes
our vorbis decoder entirely independent of dsputil.

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.

4c387c7070 ppc: dsputil: do unaligned block accesses correctly 
To load unaligned vector data in the usual way, explicit vec_ld()
should be used rather than dereferencing a pointer to a vector type.
When the VSX extension is enabled, gcc may compile vector pointer
dereferences using the VSX lxvw4x instruction instead of the lvx
instruction typically used with Altivec/VMX.  As the behaviour of
these instructions with unaligned addresses differs, it is important
that only lvx is used here.

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.

afe08a728a PPC: remove unnecessary alignment on local variables 
Storing a single element from a vector where all elements have the same
value does not require an aligned destination.  Which element is stored
depends on the alignment of the destination address, but since they all
have the same value, the result is the same regardless of the alignment.

80a61f08d2 Remove AltiVec vector declaration compiler compatibility macros. 
The original problem was that FSF and Apple gcc used a different syntax
for vector declarations, i.e. {} vs. (). Nowadays Apple gcc versions support
the standard {} syntax and versions that support {} are available on all
relevant Mac OS X versions. Thus the greater compatibility is no longer
worth cluttering the code with macros.
