Libraries:  Opus (snapshot) / Opus-tools (snapshot) / libogg 1.3
Imported:   September 15th, 2012

Steps taken to adapt original opus/opus-tool/ogg source files to rockbox
(useful when for example syncing a new snapshot)

Opus:
* copied .c/.h files from opus/src lib/rbcodec/codecs/libopus
* copied .h files from opus/include to lib/rbcodec/codecs/libopus
* copied .c/.h files from opus/celt to lib/rbcodec/codecs/libopus/celt
* copied .c/.h files from opus/silk to lib/rbcodec/codecs/libopus/silk
* renamed opus config.h file to opus_config.h and replaced #include "config.h",
  for example
find . -name "*.h" -print | xargs sed -i 's/include "config.h"/include "opus_config.h"/g'
find . -name "*.c" -print | xargs sed -i 's/include "config.h"/include "opus_config.h"/g'

Opus-tools:
* copied src/opus_header.h and src/opus_header.c to lib/rbcodec/codecs/libopus
* changed #include <ogg/ogg.h> to #include "ogg/ogg.h" in opus_header.c

Ogg:
* copied libogg/src/framing.c to lib/rbcodec/codecs/libopus/ogg
* copied libogg/include/ogg.h to lib/rbcodec/codecs/libopus/ogg
* changed #include "ogg/ogg.h" to #include "ogg.h" in framing.c
* added os_config.h to lib/rbcodec/codecs/libopus/ogg
