blkfree() takes no action for NULL pointer so callers can avoid checking.

Replace handrolled xfree() function by directly using free(3)

miscellaneous cruft:
* remove lint
* unifdef S_IFLNK, S_ISFIFO, S_ISLNK, S_ISSOCK, O_APPEND
* remove 0, NOTUSED, notdef -- untouched since original import

Convert many atoi() calls to strtonum(), adding range checks and failure
handling along the way.

When sanity checking signal numbers, error out on signal >= NSIG,
not > NSIG. This makes cvs give a nice error message for "kill
-NSIG 666" instead of EINVAL. From aaron@monkey.org.

Use strtol(), not atoi() when converting a decimal string to an integer.
That way we can catch typos when people say 'kill -HUP 65Q' and not send
the signal to process 65. Theo and myself.
