Bruce Evans daed6ffd24 Changed cncheckc() interface so that it is 8-bit clean - return -1
instead of 0 if there is no input.

syscons.c:
Added missing spl locking in sccncheckc().  Return the same value as
sccngetc() would.  It is wrong for sccngetc() to return non-ASCII, but
stripping the non-ASCII bits doesn't help.
