Check to see if postproc was enabled when enabling the
postproc visualizer was wrong.

Fix for bug introduced in Change Ia74f357d

Change-Id: I4bee9ad2caee3cfe3bac6972047f6af7c54cad4e

Debugging in postproc needs more flags to allow for specific
block types to be turned on or off in the visualizations.

Must be enabled with --enable-postproc-visualizer during
configuration time.

Use mpsadbw, and calculate 8 sad at once. Function list:
vp8_sad16x16x8_sse4
vp8_sad16x8x8_sse4
vp8_sad8x16x8_sse4
vp8_sad8x8x8_sse4
vp8_sad4x4x8_sse4

(test clip: tulip)
For best quality mode, this gave encoder a 5% performance boost.
For good quality mode with speed=1, this gave encoder a 3%
performance boost.

Solaris 10 requires -lposix4 to build successfully on gcc. I only have a
Sparc machine to test with on Solaris 10, but this change leaves
OpenSolaris x86 in a usable state w/ gnu-generic.

I am of the belief that this change should fix Solaris 10 on Sparc, but
will leave other Solaris architectures as is. If someone has an x86
Solaris 10 machine to test on, they may add x86-solaris-gcc to
libvpx/configure and give it a go.

yasm has to be preferred as currently nasm produces marginally less
efficient code (longer opcodes). Filed for nasm as:
https://sourceforge.net/tracker/?func=detail&atid=106208&aid=3037462&group_id=6208

OTOH package should be built always the same, no matter which additional
packages are / are not present on the system. As the package should be
built with nasm (as yasm may not be available) we should not use yasm
even if it is possibly available.

nasm >= approx. 2.09 is required for the nasm compilation as the former
versions had a section alignment bug.

Provide nasm compatibility. No binary change by this patch with yasm on
{x86_64,i686}-fedora13-linux-gnu. Few longer opcodes with nasm on
{x86_64,i686}-fedora13-linux-gnu have been checked as safe.

Build with -O2 rather than -O3, to dissuade the compiler from inlining
so much. See issue #1.

adds a compile time option: --enable-arm-asm-detok which pulls in
vp8/decoder/arm/detokenize.asm

currently about break even speed wise, but changes are pending to
the fill code (branch and load 3 bytes versus conditionally always
load one) and the error handling. Currently it doesn't handle zero
runs or overrunning the buffer.

this is really just so i don't have to rebase my changes all the
time to run benchmarks - now just need to replace one file!

These are mostly vestigial, it's up to the compiler to decide what
should be inlined, and this collided with certain Windows platform SDKs.

This patch adds support for building shared libraries when configured
with the --enable-shared switch.

Building DLLs would require more invasive changes to the sample
utilities than I want to make in this patch, since on Windows you can't
use the address of an imported symbol in a static initializer. The best
way to work around this is proably to build the codec interface mapping
table with an init() function, but dll support is of questionable value
anyway, since most windows users will probably use a media framework
lib like webmdshow, which links this library in staticly.

Support --prefix, --libdir as a conventional way of specifying the default
installation directories. libdir is required to be a subdirectory of prefix
at this time.

This renames the vpx_codec/ directory to vpx/, to allow applications
to more consistently reference these includes with the vpx/ prefix.
This allows the includes to be installed in /usr/local/include/vpx
rather than polluting the system includes directory with an
excessive number of includes.

Split the 'make install' target into two: install and dist. dist
retains the old make install behavior of building a "distribution"
release, with source files, build system, etc. install does what
one one expects -- installs into a tree in the filesystem, /usr/local
by default.
