The new functions (in qpeldsp.asm) occupy 8244B (the MMXEXT functions
which they will replace occupy only 6720B).

    avcodec/x86/qpeldsp{,_init}: Use SSE2 pixels16x16_l2 functions
put and avg versions have been added and used in H264
in b91081274f5a5b5f0f1ce820331f702378a425e8. This commit
adds the size 16 version of put_no_rnd and uses all three
of them in the SSE2 size 16 qpel functions (i.e. it uses
them in the ones that have a vertical component); it also
removes the 16x17 MMXEXT versions (which are no longer used).

This is particularly beneficial for put_no_rnd:

    avcodec/x86/qpeldsp: Add SSSE3 size 16 horizontal filter
Beats the mmxext version by a lot (in the following,
[0][1-3] refers to horizontal-only size 16 mc;
the _sse2 comparators for the other cases use mmxext
horizontal mc coupled with vertical SSE2 mc):

    avcodec/x86/qpeldsp: Add SSSE3 size 8 horizontal filter
Beats the mmxext version by a lot (in the following,
[1][1-3] refers to horizontal-only size 8 mc;
the _sse2 comparators for the other cases use mmxext
horizontal mc coupled with vertical SSE2 mc):

    avcodec/x86/qpeldsp: Add combination of h_lowpass + l2
If the subpel part of the horizontal component of
the motion vector is 1/4 or 3/4, the MPEG-4 qpel motion compensation
first computes the mc for the corresponding motion vector
with 1/2 horizontal subpel part and then averages this
with the left (for 1/4) or the right (for 3/4) source pixel.
These two stages are currently performed in two different functions,
involving a stack buffer as intermediate.

This means that horizontal prediction for every function with
a 1/4 or 3/4 horizontal subpel mv is more expensive code-size wise
(and also performance-wise) as it involves two calls. Given that
the horizontal lowpass functions are not that long, adding combinations
of h_lowpass+l2 actually reduces binary size: An increase of 1136B
in the asm files is more than offset by size reductions in
the wrappers: 1968B here when not using stack protection,
2256B when using stack protection.

Of course it also improves performance. Old benchmarks:
avg_qpel_pixels_tab[0][1]_ssse3:                       106.9 ( 8.69x)
avg_qpel_pixels_tab[0][3]_ssse3:                       105.5 ( 8.84x)
avg_qpel_pixels_tab[0][5]_ssse3:                       226.9 ( 8.57x)
avg_qpel_pixels_tab[0][7]_ssse3:                       231.1 ( 8.38x)
avg_qpel_pixels_tab[0][9]_ssse3:                       217.8 ( 9.04x)
avg_qpel_pixels_tab[0][11]_ssse3:                      214.9 ( 9.32x)
avg_qpel_pixels_tab[0][13]_ssse3:                      227.1 ( 8.48x)
avg_qpel_pixels_tab[0][15]_ssse3:                      236.1 ( 8.02x)

New benchmarks:
avg_qpel_pixels_tab[0][1]_ssse3:                        96.7 ( 9.65x)
avg_qpel_pixels_tab[0][3]_ssse3:                        96.6 ( 9.73x)
avg_qpel_pixels_tab[0][5]_ssse3:                       225.8 ( 8.61x)
avg_qpel_pixels_tab[0][7]_ssse3:                       228.4 ( 8.51x)
avg_qpel_pixels_tab[0][9]_ssse3:                       217.1 ( 9.05x)
avg_qpel_pixels_tab[0][11]_ssse3:                      217.8 ( 9.32x)
avg_qpel_pixels_tab[0][13]_ssse3:                      227.2 ( 8.54x)
avg_qpel_pixels_tab[0][15]_ssse3:                      220.5 ( 8.72x)

Note: The l2 functions are also used for vertical lowpass
functions, yet given that they are much bigger, duplicating
them would lead to massive code size increase.

    avcodec/x86/qpeldsp_init: Mark functions as hidden
It allows pic 32bit code to call the underlying
assembly functions directly, without loading
the GOT first; this saves 1245B of .text here
(for 32bit pic code).

    avcodec/x86/qpeldsp{,_init}: Use proper prefix
E.g. rename ff_put_mpeg4_qpel8_h_lowpass_ssse3 to
ff_mpeg4_put_qpel8_h_lowpass_ssse3.
