The CQ level was not using the q_trans[] array to convert
to a 0-127 range as per min and maxq
Experimental change to try and match the reconstruction
error for forced key frames approximately to that of the
previous frame by means of the recode loop. Though this
may cause extra recodes and the recode behavior has not
been optimized, it can only happen on forced key frames.

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.

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.

making any win32 calls in this function, just #undef it first to take

The first implementation of the firstpass motion map for motion
compensated temporal filtering created a file, fpmotionmap.stt,
in the current working directory. This was not safe for multiple
encoder instances. This patch merges this data into the first pass
stats packet interface, so that it is handled like the other
(numerical) firstpass stats.
The new stats packet is defined as follows:
Numerical Stats (16 doubles) -- 128 bytes
Motion Map -- 1 byte / Macroblock
Padding -- to align packet to 8 bytes
The fpmotionmap.stt file can still be generated for debugging
purposes in the same way that the textual version of the stats
are available (defining OUTPUT_FPF in firstpass.c)

Having these symbols be available as functions rather than data is
occasionally more convenient. Implemented this way rather than a
get-codec-by-id style to avoid creating a link-time dependency
between the encoder and the decoder.

The patch related with issue #55 (5a72620) fixed some warnings, but the
fix was not optimal. It actually was a trick to confuse compiler rather
than a fix.
This patch fixes it by creating a new macro used when needed just a high
limit check for an unsigned.

Remove the dependency on postproc.c for the encoder in general, the only
unchecked need for it is when CONFIG_PSNR is enabled. All other cases
are already wrapped in CONFIG_POSTPROC. In the CONFIG_PSNR case the file
will still be included.
Additionally, when VP8_SET_POSTPROC is used with the encoder when post
processing has been disabled an error will be returned.
This addresses issue #153.

The external API exposes the RC initial/optimal/full buffer level in
milliseconds, but this value was truncated internally to seconds. This
patch allows the use of the full precision during the conversion from
time to bits.

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 is to accommodate output packets for both compressed
data and psnr stats. For each frame, there are at least
one packet for compressed data and one for psnr stats. For
a max lag of 25, 64 is large enough to cover all lagged
frames at the end of encoding.

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.
