This patch creates some basic infrastructure for doing bitstream-
incompatible changes to the VP8 encoder. The key parts are:

 - --enable-experimental configure switch, to enable support for this
   incompatible bitstream. This switch is required to be set to enable
   any "experiments"

 - A list for "experiments" which translate into --enable-<experiment>
   options and CONFIG_<experiment> macros.

 - The high bit of the "Version" field is used to indicate that the
   bitstream was produced by an experimental encoder. The decoder will
   fail to decode an experimental bitstream without
   --enable-experimental.

 - A new "vp8x" encoder interface is created to set the experimental
   bit.

 - The vp8x encoder interface is made the default for ivfenc in
   experimental mode.

The libvpx build system was influenced by the clever design of the
FFmpeg configure script. Say so in the script header, and provide a
little introduction.

This is to accommodate output packets for both compressed
data and psnr stats. For each frame, there are at least
one packet for compressed data and one for psnr stats. For
a max lag of 25, 64 is large enough to cover all lagged
frames at the end of encoding.

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.

Try to select an optimized target based on the host's uname, as this

The output of simple_decoder, as well as the default format for the
ivf{enc,dec} tools, is I420. The encoder examples are changed to default
to I420 as well. This is desirable because passing the output of
simple_encoder to simple_decoder would otherwise have the chroma planes
flipped, which is unexpected.

The PLANE_{PACKED,Y,U,V,ALPHA} macros should be renamed to be within the
VPX_ namespace.

Fixes #27

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.

was not being selected as a gcc target, because it doesn't end in
gcc.

This doesn't play well with autotools, and the preprocessor magic is
confusing and unhelpful in the vp8-only context.

Visual c++ compiler uses xmm registers for floating point
operations for 64 bit architecture, therefore its calling
convention requires the preservation of xmm6-xmm15 in any
function that have used these registers. However, the sse2
functions, that were originally written for 32 bit windows,
may have used xmm6 and xmm7 without preserving the content.
In this particular case, the compiler used xmm6 to save
the variable "two_pass_min_rate", the value of the variable
is mucked up by our sse2 optimized loop filter functions,
hence the results of release/debug mismatching.
