get rid of unused entries in the middle of xvmc_render struct,
extensions are added to the end of the struct (avoids build issues on 64 bits platform)
add osd extension to be used by mplayer (required by the resent changes in the build system)
breaking the compability, thus bumping minor lavc version number

move eob_reached logic into ff_lzw_decode_tail() which simplifies the code, avoids some checks in the innermost loop and also gets rid of the controversal break while hopefully retaining the last byte in a valid bytestream, invalid bytestreams still can have very significant overread

Fix H.264 8x8 transform selection
It seems that it's opt parse bug, it can't process the flags which start by
digit. After change 8x8dct to dct8x8, I can set it without problem. I guess
nobody will use it since it can't work as expected, so the quick fix is change
the option name.
