hoaparse: rename to parseaut

Because this parser is not specific to HOA anymore.

* src/hoaparse/Makefile.am, src/hoaparse/fmterror.cc,
src/hoaparse/hoaparse.yy, src/hoaparse/parsedecl.hh,
src/parseaut/public.hh, src/hoaparse/hoascan.ll,
src/tests/hoaparse.test: Rename to...
* src/parseaut/Makefile.am, src/parseaut/fmterror.cc,
src/parseaut/parseaut.yy, src/parseaut/parsedecl.hh,
src/hoaparse/public.hh, src/parseaut/scanaut.ll,
src/tests/parseaut.test: ... these, and also adjust the name internally.
For instance hoa_aut_ptr is now parsed_aut_ptr; hoa_stream_parser is now
automaton_stream_parser, and hoa_parse() has become parse_aut().
