fix symbol collision, seen with clang-3.5
autfilt would segfault after reading any file, because the local result_ structure used in hoaparse has the same name as the local result_ structure used in dstarparse. For some reason I can only see this problem using clang-3.5, not with gcc. * src/dstarparse/dstarparse.yy, src/hoaparse/hoaparse.yy: Declare both structures in a different namespace.
