Use uint32_t instead of size_t counts (halves size of ChanCount on 64-bit). Shift DataType values down to eliminate subtraction every index of a ChanCount or *Set. Allow using DataType directly as an array index (prettier/terser). Fix some mixed spaces/tabs in file comment headers. git-svn-id: svn://localhost/ardour2/trunk@2082 d708f5d6-7413-0410-9779-e7cbd77b26cf
