remove unused and unneeded:
- sysexit_status
- type (a global variable)
add mrb_ prefix to:
- codedump_all
- class_instance_method_list
- parser_dump
make various functions static, incl.:
- yyparse
- make_exception
- more descriptive name (there's no mrb_exc_new2)
- no wrapper (macro/static inline function) for
backwards compatibility because nothing besides
mruby itself seems to be calling this function:
<http://mruby-code-search.ongaeshi.me/home?query=mrb_exc_new3>
