Create a new input parameter to allow specifying
the packed frame stereo 3d format. A default value
of mono will be written in the absence of user
specified input

Identified as a possible cause of issue #308, the code was silently
ignoring realloc failures, which would lead to corruption, memory
leaks, and likely a crash. The best we can do in this case is die
gracefully.

Map an enum to the --end-usage values, so you can specify
--end-usage=cq instead of --end-usage=2. The numerical values still
work for historical scripts, etc, but this is more user friendly.

Cast size_t to (unsigned long) and print it with the %lu format
string, which is more portable than C99's explict %zu for size_t.
This truncates on Windows x64 but otherwise works on 32 and 64 bit
platforms. In practice the stats file is unlikely to be so large.

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.

The merge includes hooks to for CQ mode and other code
changes merged from the test branch.
CQ mode attempts to maintain a more stable quantizer within a clip
whilst also trying to adhere to a guidline maximum bitrate.
The existing target data rate parameter is used to specify the
guideline maximum bitrate.
A new parameter allows the user to specify a target CQ level.
For normal (non kf/gf/arf) frames, the quantizer will not drop BELOW the
user specified value (0-63). However, in some cases the encoder may
choose to impose a target CQ that is above that specified by the user,
if it estimates that consistent use of the target value is not compatible
with guideline maximum bitrate.

stats_close() was not freeing memory for
single pass runs. It now takes in arg_passes
to determine when it should free memory.

Add a new encoder control, VP8E_SET_TUNING, to allow the application
to inform the encoder that the material will benefit from certain
tuning. Expose this control as the --tune option to vpxenc. The args
helper is expanded to support enumerated arguments by name or value.
Two tunings are provided by this patch, PSNR (default) and SSIM.
Activity masking is made dependent on setting --tune=ssim, as the
current implementation hurts speed (10%) and PSNR (2.7% avg,
10% peak) too much for it to be a default yet.

read_frame would incorrectly insert detect->buf into img
for ivf files. detect->position now set to 4 if input file is
detected to be ivf in file_is_ivf to keep this from occuring.

Change Ice204e86 identified a problem with bitrate undershoot due to
low precision in the timestamps passed to the library. This patch
takes a different approach by calculating the duration of this frame
and passing it to the library, rather than using a fixed duration
and letting the library average it out with higher precision
timestamps. This part of the fix only applies to vpxenc.
This patch also attempts to fix the problem for generic applications
that may have made the same mistake vpxenc did. Instead of
calculating this frame's duration by the difference of this frame's
and the last frame's start time, we use the end times instead. This
allows the framerate calculation to scavenge "unclaimed" time from
the last frame. For instance:
start | end | calculated duration
======+=======+====================
0ms 33ms 33ms
33ms 66ms 33ms
66ms 99ms 33ms
100ms 133ms 34ms

The old value 1000 was too low, which caused the effective duration and
frame rate calculation to have an 1% error for typical 30 frame/second
inputs. Symptom of the issue has been that most 2 pass encodings were
undershooting target bit rate by 1% or so for 30 fps input.

Defaulting to 320x240 for raw streams is arbitrary and error-prone.
Instead, require that the width and height be set manually if they
can't be parsed from the input file.

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.

This eliminates a large set of warnings exposed by the Mozilla build
system (Use of C++ comments in ISO C90 source, commas at the end of
enum lists, a couple incomplete initializers, and signed/unsigned
comparisons).
It also eliminates many (but not all) of the warnings expose by newer
GCC versions and _FORTIFY_SOURCE (e.g., calling fread and fwrite
without checking the return values).
There are a few spurious warnings left on my system:
../vp8/encoder/encodemb.c:274:9: warning: 'sz' may be used
uninitialized in this function
gcc seems to be unable to figure out that the value shortcut doesn't
change between the two if blocks that test it here.
../vp8/encoder/onyx_if.c:5314:5: warning: comparison of unsigned
expression >= 0 is always true
../vp8/encoder/onyx_if.c:5319:5: warning: comparison of unsigned
expression >= 0 is always true
This is true, so far as it goes, but it's comparing against an enum, and the C
standard does not mandate that enums be unsigned, so the checks can't be
removed.

If --psnr option is enabled vpxenc will output PSNR values for the
entire file. Added a \n before final output to make sure the output
is on its own line. Overall and Avg psnr matches the values written
to opsnr.stt file.

MKV requires a unique(ish) TrackID element in the track info header.
Instead of the current hard-coded ID, take a hash of the video track
and use that. This value is not written in the deterministic output
mode, despite being a deterministic value itself, to give flexibility
to change the hash algorithm and not affect bisecting across the
change.

By baking the version number into the output file, a hash of the file
will vary from commit to commit, even if the output is otherwise bit
exact. Add a -D option to suppress this behavior, for use when
bisecting or other debugging.

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.
