d04f852368 Adding error-concealment to the decoder.
The error-concealer is plugged in after any motion vectors have been
decoded. It tries to estimate any missing motion vectors from the
motion vectors of the previous frame. Intra blocks with missing
residual are replaced with inter blocks with estimated motion vectors.

This feature was developed in a separate sandbox
(sandbox/holmer/error-concealment).

bbf890fe27 build: change LDFLAGS/CFLAGS ordering.
Always use CFLAGS/LDFLAGS that point to headers and libvpx.a inside our
build tree before ones from the environment, which could reference
headers or libs outside the build tree.

This fixes issue 307.

11a222f5d9 Adds "armvX-none-rvct" targets
Adds following targets to configure script to support RVCT compilation
without operating system support (for Profiler or bare metal images).
 - armv5te-none-rvct
 - armv6-none-rvct
 - armv7-none-rvct

To strip OS specific parts from the code "os_support"-config was added
to script and CONFIG_OS_SUPPORT flag is used in the code to exclude OS
specific parts such as OS specific includes and function calls for
timers and threads etc. This was done to enable RVCT compilation for
profiling purposes or running the image on bare metal target with
Lauterbach.

Removed separate AREA directives for READONLY data in armv6 and neon
assembly files to fix the RVCT compilation. Otherwise
"ldr <reg>, =label" syntax would have been needed to prevent linker
errors. This syntax is not supported by older gnu assemblers.

c377bf0eec fix pipe support on windows
STDIO streams are opened in text mode by default on Windows. This patch
changes the stdin/stdout streams to be in binary mode if they are being
used for I/O from the vpxenc or vpxdec tools.

Fixes issue #216. Thanks to mw AT hesotech.de for the fix.

3427e1dd43 makefile: remove ivf{enc,dec} on make clean
Prior clean-up removed the object files, but not the binaries
themselves.

ea68ee0458 rename ivf{enc,dec} to vpx{enc,dec}
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.

dc66630cca ivfenc: webm output support
This patch adds the --webm option, to allow the creation of WebM streams
without having to remux ivf into webm.

ad252daf65 ivfdec: webm reader support
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.

c2140b8af1 Use WebM in copyright notice for consistency
Changes 'The VP8 project' to 'The WebM project', for consistency
with other webmproject.org repositories.

94c52e4da8 cosmetics: trim trailing whitespace
When the license headers were updated, they accidentally contained
trailing whitespace, so unfortunately we have to touch all the files
again.

44d8949553 Add support for reading YUV4MPEG2 files to ivfenc.
A large collection of example files may be found at
 http://media.xiph.org/video/derf/
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.

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.

ee8bcb1a7d make: make install target behave as expected
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.
