Instead of parsing every multibyte character twice, first with
parse_mbchar() and then with mbtowc(), just let mbtowc() do all
the work.  This makes searching for a fixed string twice as fast.

This also gets rid of four variables and lots of memory allocations.
(And, more importantly: it stops nano messing up the internal state
of the multibyte-to-wide character conversion, and thus would make
the calls to mbtowc_reset() superfluous.)

(The measurable effect (during long searches, for example) is zero, though.)

Apparently there is /some/ state somewhere after all.  Don't have time
now to figure out where exactly.

Speedup suggested by Mark Majeres.

        * src/chars.c (addstrings): Needs to be available even on
          non-utf-8 sustems.
        * nano-regress: Added --disable-utf8 to regression check
