iedowse 7f0150c9c9 Fix some very broken code in __nc_error() that implements per-thread
`nc_error' variables. Move the nc_lock mutex from mt_misc.c to a
static variable within this function, since it is only used here.

Add a new getnetconfigent() error code `NC_NOTFOUND' to report the
case where the specified netid was not found. Set nc_error in all
error cases in getnetconfigent() so that the error messages returned
by nc_(s)perror are always meaningful.

Add a terminating \n to the output of nc_perror() to match both
our manpage and other implementations of this function.
