- Move IVF reading support into ivfdec.c and ivfdec.h
- Move IVF writing support into ivfenc.c and ivfenc.h
- Removed IVF writing code from the SVC example in favor of ivfenc.

The new WebM output support should be preferred to IVF, but we can't
change the default behavior of the ivf* tools. There are a few other
default behaviors for these tools that are counterintuitive for
historical reasons, and changing the binary name provides the
opportunity to clean those up as well. This patch takes the first
step by renaming the binaries.

This patch adds the --webm option, to allow the creation of WebM streams
without having to remux ivf into webm.

Ivfenc will use timebase if it is set. If it is not set ivfenc will
still double the timebase so altref frames will have a unique pts.
Patch Set #3: Use integer math to generate source pts. Added a
framerate parameter. Increased the default timebase to milliseconds to
remove the *2 everywhere.

An earlier automatic transform changed eg '\nOptions' to '\n_options'
which is incorrect in these printfs. Fix these.

The timebase was being set to the value in the Y4M file on each
 pass, but only doubled to account for the altref placement on
 the first past.
This avoids reseting it on the second pass.

ivfenc was setting the VPX_KF_FIXED mode when the kf_min_dist and
kf_max_dist parameters were set to each other. This flag actually means
that keyframes are disabled, and that name was deprecated to avoid
confusion such as this. Instead, a new option is exposed for setting the
VPX_KF_DISABLED mode, and the intervals are passed through to the codec,
which will do automatic placement at a fixed interval as expected.

This change stops ivfenc from treating unsupported Y4M files as raw
input.

For example, if given an interlaced Y4M file, ivfenc treated the input
as if it were raw data because the unsupported Y4M file case previously
fell through without being handled.

Commit 3245d463 "ivfenc: support reading/writing from a pipe" broke
support for two pass encodes of raw files when done in two
invocations of ivfenc. The raw image was only set up on pass 0,
which was never hit when running with --pass=2 --passes=2.

Use - for the filename to use stdin/stdout. Update to avoid opening

This also fixes a bug in ivfenc for uncompressed IVF input, which previously
 appeared not to skip past the file header the second time it opened the file.
I don't actually have an IVF file with which to test this fix, however.

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 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.

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