Use ANSI C prototypes. Eliminates -Wold-style-definition warnings.

r300387:

getnetid(..): consistently fclose fd at the end of the function

This mutes a false positive with cppcheck, but also helps eliminate future
potential issues with this variable

r300388:

Call endnetconfig on nc_handle sooner to avoid leaking nc_handle if tmpnconf
was NULL

This would theoretically happen if the netconfig protocol family and protocol
semantics were never matched.

r300389:

nis_rpcent: don't leak resultbuf from yp_first(..)/yp_next(..)

If the buffer couldn't be adequately resized to accomodate an additional "\n",
it would leak resultbuf by breaking from the loop early
