7aa97a35b5 shared library support (.so)
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.

0952acb79a setup experimental infrastructure
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.

d33bf3d664 Remove costly memory reads/writes in vp8_reset_mb_tokens_context()
Tests on x86 showed this function costed 2.7% of total decoding time
because of all the memory reads/writes. After modification, it only
costs about 0.7% of decoding time, which gives a 2% gain.

8caa5c2d30 Increase the size of output packet list
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.

b6c71918ae vpx_image: add VPX_ prefix to PLANE_*
The PLANE_{PACKED,Y,U,V,ALPHA} macros should be renamed to be within the
VPX_ namespace.

b7492341ac install includes in DIST_DIR/include/vpx, move vpx_codec/ to vpx/
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.

1df0314e7b configure: remove HAVE_CONFIG_H
This doesn't play well with autotools, and the preprocessor magic is
confusing and unhelpful in the vp8-only context.

c15652bce1 Fixed an encoder debug/relese mismatch in x86_64-win64-vs8
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.
