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.

Having static data tables in header files is a potential source of trouble.

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.

This makes sure that the restrict keyword is mapped to whatever
keyword the compiler prefers/supports. This fixes building on MSVC
(and possibly on GCC 2.x as well).

This makes the aac decoder and all voice codecs independent of dsputil.

This makes wmadec/enc, twinvq and mpegaudiodec (i.e. mp2/mp3)
independent of dsputil.

Now, nellymoserenc and aacenc no longer depends on dsputil. Independent
of this patch, wmaprodec also does not depend on dsputil, so I removed
it from there also.

This provides a fallback when building with Yasm enabled, but neither
inline assembly, nor the _mm_empty intrinsic are available or enabled.

This allows defining externally visible library symbols.

The new name is more descriptive and will allow defining a separate
public prefix for externally visible library symbols.

%f denotes a double argument and 'l' does nothing in this case
according to the C spec.

Fixes build errors with nasm introduced in 6f40e9f070 for stack
memory alignment. Noticed by BugMaster.

Use this in VP8/H264-8bit loopfilter functions so they can be used if
there is no aligned stack (e.g. MSVC 32bit or ICC 10.x).

This allows compiling optimised functions for features not enabled
in the core build and selecting these at runtime if the system has
the necessary support.
