The assert is not removed as the assert ensures clear and easy
to debug failures instead of undefined behavior in case of
misalignment.

Merged-by: Michael Niedermayer <michaelni@gmx.at>

E is usually defined as a shorthand for AV_OPT_FLAG_ENCODING_PARAM.
Rename the single expansion E(x) now used in libavutil to E1.

These functions are mostly H264-specific (the only other user I can
spot is bink), and this allows us to special-case some functionality
for H264. Also remove the 16-bit-coeff with >8bpp versions (unused)
and merge the duplicate 32-bit-coeff for >8bpp (identical).

Also use the resulting 16bpp functions for anything >8 and <=16, not just
9 and 10. This fixes 12 and 14bpp H264 support.

This allows employing that number in library install commands.

This is what the OpenBSD porter's manual describes as correct, cf.

This reverts parts of d6d5ef55, that didn't work right. (The
tests that were added failed on big endian, and the output looked
garbled on little endian as well.)

This is due to the fact that the intermediate scaling values (from
e.g. hScale8To19_c or hScale16To19_c) are stored as int32_t and
thus requires a separate output function, while yuv2gbrp_full_X_c
only interprets it as int16_t.

On recent android versions, /proc/self/auxw is unreadable
(unless the process is running running under the shell uid or
in debuggable mode, which makes it hard to notice). See
http://b.android.com/43055 and
https://android-review.googlesource.com/51271 for more information
about the issue.

This makes sure e.g. neon optimizations are enabled at runtime in
android apps even when built in release mode, if configured to
use the runtime detection.
