New function (derived from sbbs_t::utf8_to_cp437()): unicode_to_cp437()
New utf8 functions: utf8_replace_chars(), utf8_str_is_valid().
utf8_getc() enhancement: val arg may be NULL (for length/validation uses).

UNICODE -> CP437 conversions (no string/memory compares needed), so
cp437_utf8_tbl.* is being replaced by cp437_unicode_tbl.*.

Added utf8 module which includes:
- utf8_normalize_str() - normalize US-ASCIIZ string, from mailsrvr.c
- utf8_putc() - encoder / length calculator
- utf8_getc() - decoder

The latter 2 were swiped from OpenSSL's a_utf8.c.

You will need to perform a clean rebuild.
