MMX patch to speed up Theora decoding
...lf Marek's patch in
http://lists.xiph.org/pipermail/theora-dev/2005-July/002816.html
and the code in http://svn.xiph.org/trunk/vp32/CoreLibs/CDXV/Vp31/dx/win32/
* change FiltBoundingValue to ogg_int16_t and reduce it to 256
entries. (It is safe if I read the spec correctly)
* comment out unused idct_short__c, remove unused LoopFilterLimitValuesV2
An --enable-mmx option is added to configure (you need to run
autogen.sh to enable it after patch). Compile time switch is used
instead of a runtime one because it seems easier to me :)
