Initial OpenCL implementation of the VP8 decoder.

Change-Id: I74c334af09f13473ce07bbac74b0f9ea57573347
Note: very slow, but functional.  Encoder is untested, but should still work.

+2011-03-07 v0.9.6 "Bali"
+  Our second named release, focused on a faster, higher quality, encoder.
+
+  - Upgrading:
+    This release is backwards compatible with Aylesbury (v0.9.5). Users
+    of older releases should refer to the Upgrading notes in this
+    document for that release.
+
+  - Enhancements:
+      vpxenc --psnr shows a summary when encode completes
+      --tune=ssim option to enable activity masking
+      improved postproc visualizations for development
+      updated support for Apple iOS to SDK 4.2
+      query decoder to determine which reference frames were updated
+      implemented error tracking in the decoder
+      fix pipe support on windows
+
+  - Speed:
+      Primary focus was on good quality mode, speed 0. Average improvement
+      on x86 about 40%, up to 100% on user-generated content at that speed.
+      Best quality mode speed improved 35%, and realtime speed 10-20%. This
+      release also saw significant improvement in realtime encoding speed
+      on ARM platforms.
+
+        Improved encoder threading
+        Dont pick encoder filter level when loopfilter is disabled.
+        Avoid double copying of key frames into alt and golden buffer
+        FDCT optimizations.
+        x86 sse2 temporal filter
+        SSSE3 version of fast quantizer
+        vp8_rd_pick_best_mbsegmentation code restructure
+        Adjusted breakout RD for SPLITMV
+        Changed segmentation check order
+        Improved rd_pick_intra4x4block
+        Adds armv6 optimized variance calculation
+        ARMv6 optimized sad16x16
+        ARMv6 optimized half pixel variance calculations
+        Full search SAD function optimization in SSE4.1
+        Improve MV prediction accuracy to achieve performance gain
+        Improve MV prediction in vp8_pick_inter_mode() for speed>3
+
+  - Quality:
+      Best quality mode improved PSNR 6.3%, and SSIM 6.1%. This release
+      also includes support for "activity masking," which greatly improves
+      SSIM at the expense of PSNR. For now, this feature is available with
+      the --tune=ssim option. Further experimentation in this area
+      is ongoing. This release also introduces a new rate control mode
+      called "CQ," which changes the allocation of bits within a clip to
+      the sections where they will have the most visual impact.
+
+        Tuning for the more exact quantizer.
+        Relax rate control for last few frames
+        CQ Mode
+        Limit key frame quantizer for forced key frames.
+        KF/GF Pulsing
+        Add simple version of activity masking.
+        make rdmult adaptive for intra in quantizer RDO
+        cap the best quantizer for 2nd order DC
+        change the threshold of DC check for encode breakout
+
+  - Bug Fixes:
+      Fix crash on Sparc Solaris.
+      Fix counter of fixed keyframe distance
+      ARNR filter pointer update bug fix
+      Fixed use of motion percentage in KF/GF group calc
+      Changed condition for using RD in Intra Mode
+      Fix encoder real-time only configuration.
+      Fix ARM encoder crash with multiple token partitions
+      Fixed bug first cluster timecode of webm file is wrong.
+      Fixed various encoder bugs with odd-sized images
+      vp8e_get_preview fixed when spatial resampling enabled
+      quantizer: fix assertion in fast quantizer path
+      Allocate source buffers to be multiples of 16
+      Fix for manual Golden frame frequency
+      Fix drastic undershoot in long form content
+
+
+2010-10-28 v0.9.5 "Aylesbury"
+  Our first named release, focused on a faster decoder, and a better encoder.
+
+  - Upgrading:
+    This release incorporates backwards-incompatible changes to the
+    ivfenc and ivfdec tools. These tools are now called vpxenc and vpxdec.
+
+    vpxdec
+      * the -q (quiet) option has been removed, and replaced with
+        -v (verbose). the output is quiet by default. Use -v to see
+        the version number of the binary.
+
+      * The default behavior is now to write output to a single file
+        instead of individual frames. The -y option has been removed.
+        Y4M output is the default.
+
+      * For raw I420/YV12 output instead of Y4M, the --i420 or --yv12
+        options must be specified.
+
+          $ ivfdec -o OUTPUT INPUT
+          $ vpxdec --i420 -o OUTPUT INPUT
+
+      * If an output file is not specified, the default is to write
+        Y4M to stdout. This makes piping more natural.
+
+          $ ivfdec -y -o - INPUT | ...
+          $ vpxdec INPUT | ...
+
+      * The output file has additional flexibility for formatting the
+        filename. It supports escape characters for constructing a
+        filename from the width, height, and sequence number. This
+        replaces the -p option. To get the equivalent:
+
+          $ ivfdec -p frame INPUT
+          $ vpxdec --i420 -o frame-%wx%h-%4.i420 INPUT
+
+    vpxenc
+      * The output file must be specified with -o, rather than as the
+        last argument.
+
+          $ ivfenc <options> INPUT OUTPUT
+          $ vpxenc <options> -o OUTPUT INPUT
+
+      * The output defaults to webm. To get IVF output, use the --ivf
+        option.
+
+          $ ivfenc <options> INPUT OUTPUT.ivf
+          $ vpxenc <options> -o OUTPUT.ivf --ivf INPUT
+
+
+  - Enhancements:
+      ivfenc and ivfdec have been renamed to vpxenc, vpxdec.
+      vpxdec supports .webm input
+      vpxdec writes .y4m by default
+      vpxenc writes .webm output by default
+      vpxenc --psnr now shows the average/overall PSNR at the end
+      ARM platforms now support runtime cpu detection
+      vpxdec visualizations added for motion vectors, block modes, references
+      vpxdec now silent by default
+      vpxdec --progress shows frame-by-frame timing information
+      vpxenc supports the distinction between --fps and --timebase
+      NASM is now a supported assembler
+      configure: enable PIC for shared libs by default
+      configure: add --enable-small
+      configure: support for ppc32-linux-gcc
+      configure: support for sparc-solaris-gcc

+      including:
+        Rewrite vp8_short_walsh4x4_sse2()
+        Optimizations on the loopfilters.
+        Miscellaneous improvements for Atom

+        Improved multithread utilization
+        Better instruction choices on x86
+        reorder data to use wider instructions
+        Update NEON wide idcts

+        Add SSE2 subtract functions
+        Improve bounds checking in vp8_diamond_search_sadx4()
+        Added vp8_fast_quantize_b_sse2
+
+  - Quality:
+      Over 7% overall PSNR improvement (6.3% SSIM) in "best" quality
+      encoding mode, and up to 60% improvement on very noisy, still
+      or slow moving source video
+
+        Motion compensated temporal filter for Alt-Ref Noise Reduction
+        Improved use of trellis quantization on 2nd order Y blocks
+        Tune effect of motion on KF/GF boost in two pass
+        Allow coefficient optimization for good quality speed 0.
+        Improved control of active min quantizer for two pass.
+        Enable ARFs for non-lagged compress
+
+2010-09-02 v0.9.2

+      Swap alt/gold/new/last frame buffer ptrs instead of copying.
+      Improve SSE2 loopfilter functions
+      Change bitreader to use a larger window.
+      Avoid loopfilter reinitialization when possible

+- Test (and fix, if necessary) support for large files.
+- Read past unknown elements rather than seeking.
+- Try to handle unknown elements with unknown sizes.

+- Optionally build a Cue index as Clusters are parsed.
+- Support seeking without Cues.
+- Avoid building a list of Clusters as they are parsed and retain only the

+- Add an asynchronous error code to struct nestegg and ensure that API calls
+  continue to fail safely one a fatal error has been returned.
+- Modify parser/data structures to provide a clean separation.  Perhaps the

+halloc 1.2.1
+============
+      
+	Hierarchical memory heap interface - an extension to standard
+	malloc/free interface that simplifies tasks of memory disposal 
+	when allocated structures exhibit hierarchical properties.
+
+	http://swapped.cc/halloc
+=
+	To build libhalloc.a with GNU tools run
+		make
+
+	To install in /usr/include and /usr/lib
+		make install
+
+	To cleanup the build files 
+		make clean
+=
+	halloc-1.2.1
+		* fixed a double-free bug in _set_allocator() as per
+		  Matthew Gregan comments
+
+		* switched to using NULL instead of 0 where applicable
+
+	halloc-1.2.0
+		* added missing <string.h> include to halloc.c
+		
+		* improved standard compliance thanks to the feedback
+		  received from Stan Tobias. Two things were fixed -
+		  
+		- hblock_t structure no longer uses zero-sized 'data'
+		  array, which happened to be common, but non-standard
+		  extension; 
+		  
+		- secondly, added the code to test the behaviour of 
+		  realloc(ptr, 0). Standard allows it NOT to act as
+		  free(), in which case halloc will use its own version
+		  of allocator calling free() when neccessary.
+
+	halloc-1.1.0
+		* initial public release (rewrite of hhmalloc library)

+dnl @synopsis AX_CREATE_STDINT_H [( HEADER-TO-GENERATE [, HEDERS-TO-CHECK])]
+dnl
+dnl the "ISO C9X: 7.18 Integer types <stdint.h>" section requires the
+dnl existence of an include file <stdint.h> that defines a set of
+dnl typedefs, especially uint8_t,int32_t,uintptr_t. Many older
+dnl installations will not provide this file, but some will have the
+dnl very same definitions in <inttypes.h>. In other enviroments we can
+dnl use the inet-types in <sys/types.h> which would define the typedefs
+dnl int8_t and u_int8_t respectivly.
+dnl
+dnl This macros will create a local "_stdint.h" or the headerfile given
+dnl as an argument. In many cases that file will just "#include
+dnl <stdint.h>" or "#include <inttypes.h>", while in other environments
+dnl it will provide the set of basic 'stdint's definitions/typedefs:
+dnl
+dnl   int8_t,uint8_t,int16_t,uint16_t,int32_t,uint32_t,intptr_t,uintptr_t
+dnl   int_least32_t.. int_fast32_t.. intmax_t
+dnl
+dnl which may or may not rely on the definitions of other files, or
+dnl using the AC_CHECK_SIZEOF macro to determine the actual sizeof each
+dnl type.
+dnl
+dnl if your header files require the stdint-types you will want to
+dnl create an installable file mylib-int.h that all your other
+dnl installable header may include. So if you have a library package
+dnl named "mylib", just use
+dnl
+dnl      AX_CREATE_STDINT_H(mylib-int.h)
+dnl
+dnl in configure.ac and go to install that very header file in
+dnl Makefile.am along with the other headers (mylib.h) - and the
+dnl mylib-specific headers can simply use "#include <mylib-int.h>" to
+dnl obtain the stdint-types.
+dnl
+dnl Remember, if the system already had a valid <stdint.h>, the
+dnl generated file will include it directly. No need for fuzzy
+dnl HAVE_STDINT_H things... (oops, GCC 4.2.x has deliberatly disabled
+dnl its stdint.h for non-c99 compilation and the c99-mode is not the
+dnl default. Therefore this macro will not use the compiler's stdint.h
+dnl - please complain to the GCC developers).
