Right now only IVF format is supported which is enough for example code.
Other formats like y4m, webm, raw yuv will be supported later.

New API is supposed to be used from example code. Current implementation
only supports IVF containers (will be extended to Y4M).

File type check inside ivf_read_frame() is not necessary (it is done
before this function get called).

- 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.

The width and height needed to write the Y4M header can be found by
probing the stream with vpx_codec_peek_stream_info(). This also
has the consequence of supporting multiple codecs from raw files
with automatic detections, should we add additional codecs in the
future.

This patch enables ivfdec to decode WebM files. WebM demuxing is
provided by the Matthew Gregan's Nestegg library.
This patch also makes minor changes to the timebase->framerate
handling when doing Y4M output. For WebM files, the framerate is
guessed by looking at the first second of video. For IVF files,
the timebase=1/(2*fps) hack is still in place, but is only used
if the timebase denominator is less than 1000. This is in anticipation
of change I8d25b5b, which introduces the distinction between
framerate and timebase to ivfenc. In the case of high resolution
timebases, like 100ns, we would have to guess the framerate
like we do for WebM, but since WebM support in ivfenc will
deprecate IVF output, we just assume 30fps rather than writing the
lookahead code.

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

Changes 'The VP8 project' to 'The WebM project', for consistency
with other webmproject.org repositories.
Fixes issue #97.

When the license headers were updated, they accidentally contained
trailing whitespace, so unfortunately we have to touch all the files
again.

The RSA Data Security, Inc. implementation license bears a requirement
similar to the old problematic BSD license with advertising clause.

These files can be played back directly in most major open-source media
frameworks without the need for additional patches or parameters.

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.
