options_table: Remove a now unnecessary include of config.h

The include of config.h was added in 2012 in 1d9c2dc8, due to
the use of CONFIG_SNOW_ENCODER ifdefs within options_table.h.
When the snow codec was dropped later (in a0c5917f8 in 2013),
this include no longer served any purpose.

options_table.h is included in builds for the host as well, when
building documentation. config.h should not be included in code
that is built for the host, since it can contain workarounds
for the target compiler/environment, like adding a missing define
of restrict, defining getenv(x) to NULL for environments that lack
getenv.

The seemingly innocent include reordering in 2025d37871 broke
builds that have getenv(x) defined to NULL in config.h (Windows CE
and Windows Phone/RT), since libavcodec/options_table.h include
config.h, while libavformat/options_table.h end up bringing in
more system headers, and those system headers can contain a proper
definition of getenv, which clash with the getenv define in config.h.
This was avoided earlier as long as libavformat/options_table.h (or
avformat.h) was included before libavcodec/options_table.h.

This fixes builds for Windows Phone/RT and CE.

arm: vp9: Add NEON optimizations of VP9 MC functions

This work is sponsored by, and copyright, Google.

The filter coefficients are signed values, where the product of the
multiplication with one individual filter coefficient doesn't
overflow a 16 bit signed value (the largest filter coefficient is
127). But when the products are accumulated, the resulting sum can
overflow the 16 bit signed range. Instead of accumulating in 32 bit,
we accumulate the largest product (either index 3 or 4) last with a
saturated addition.

(The VP8 MC asm does something similar, but slightly simpler, by
accumulating each half of the filter separately. In the VP9 MC
filters, each half of the filter can also overflow though, so the
largest component has to be handled individually.)

vp9_put_8tap_smooth_64v_neon:   10.69  13.30   9.43  14.34

For the larger 8tap filters, the speedup vs C code is around 5-14x.

This is significantly faster than libvpx's implementation of the same
functions, at least when comparing the put_8tap_smooth_64 functions
(compared to vpx_convolve8_horiz_neon and vpx_convolve8_vert_neon from
libvpx).

Absolute runtimes from checkasm:
                          Cortex      A7        A8        A9       A53
vp9_put_8tap_smooth_64h_neon:    20150.3   14489.4   19733.6   10863.7

libvpx vpx_convolve8_vert_neon:  42090.0   17706.2   17659.9   16941.2

Thus, on the A9, the horizontal filter is only marginally faster than
libvpx, while our version is significantly faster on the other cores,
and the vertical filter is significantly faster on all cores. The
difference is especially large on the A7.

The libvpx implementation does the accumulation in 32 bit, which
probably explains most of the differences.
