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.

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.

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