When system calls indicate an error they return -1, not some arbitrary
value < 0. errno is only updated in this case. Change all (most?)
callers of syscalls to follow this better, and let's see if this strictness
helps us in the future.

When upcasting to off_t for multiplication, the cast needs to be *before*
the multiplication to avoid truncation/overflow

ok krw@

Remove unnecessary netinet/in_systm.h include.

ok millert@

Include file order must be "monitor.h" before "extern.h" otherwise enum
auth_ret is referenced before it is declared, which is not allowed by C99.

Ok krw@, millert@, gilles@

include sys/time.h to get struct timeval

use gettimeofday() instead of time() in functions called from signal handlers; henning ok

spacing

make this match protos; millert ok

ansi cleanup; ok ian markus

fix some more UCB term 3

kill more registers;

millert@ ok

indent

ftpd: sleep for an indeterminate amount for non-existant logins
to simulate a crypt, like login does.
Use SEEK_* not L_* and kill some 0L's used in lseek while we're there.

my netbsd pr#2217: add utmp support to ftpd, some other small changes/fixes.
