Subject: [PATCH] dfa: separate parse and compile phase

DFAMUST() must be called after parse and before tokens re-order which is
introduced in commit 5c7a0371823876cca7a1347fa09ca26bbbff0c98, but both are
executed in compilation phase.

* lib/dfa.c (dfaparse): Change it to global function.
(dfacomp): If first argument is NULL, skip parse.
* lib/dfa.h: (dfaparse): Add a prototype.
