changed _noninterleaved functions to _int and changed related descriptions appropriately added an _int version of SDX2 and reverted to pre-322 behavior for normal deocder made the various get_high_nibble globals all be the same vgmstream->get_high_nibble for thread safety and code consolidation (this required some changes to make decode functions take VGMSTREAM rather than VGMSTREAMCHANNEL) git-svn-id: https://vgmstream.svn.sourceforge.net/svnroot/vgmstream@323 51a99a44-fe44-0410-b1ba-c3e57ba2b86b
