Now dfa is not support range, collating element, equivalent class in
non-POSIX locales. We can do dfa more simply by removing codes for them.
First, I made update dfaexec_main. Now transit_state is called only
when next character matches with ANYCHAR, and match_anychar always
returns the length
Uninitialized value of variable BACKREF is referred in EGexecute. It
does not cause wrong result, but regex may be used even when it is not
needed. It may lead grep to slowdown.
By the way, gawk initializes the variable already, so it does not have
to be fixed.
