Log Message:
sbbsecho: don't cut UTF-8 header fields mid-character on export

FTS-0001 packed-message headers hold 35 bytes of To/From and 71 bytes of
Subject. SMB header fields are unbounded, so export truncates them, and it
did so by byte count: a UTF-8 field over the limit (e.g. a Cyrillic name,
2 bytes per letter) could end in a partial multi-byte sequence, which
readers show as a replacement character.

Echomail export and create_netmail() now copy these fields with
utf8_strlcpy() when the message's header fields are UTF-8 and valid, so the
cut falls on a character boundary. On ASCII-only (SUB_ASCII) sub-boards
the field is converted from UTF-8 to CP437/ASCII before truncation rather
than after, so it no longer converts an already-split sequence and keeps
up to twice as many characters.

Fixes #1276
