This hides the unavoidably cruddy sys/param.h namespace in some programs.
Little impact, because many programs are cruddy and still get it via
other includes.

instead, #define to __builtin_alloca. if that doesn't work, you're hosed.

other systems to fit into the same mold, so add copyright

daemon.
Old drift files will be interpreted as a minuscule adjustment and
ntpd will proceed to rediscover the drift, like starting from zero
on a newly installed machine.

- Nothing seems to free the result of host_dns(), so add host_dns_free() and
call after each query.
- If imsg_add() fails, it frees buf. Avoid subsequently dereferencing the
freed buf in imsg_close().

floppy. A few drivers are missing, but the world has moved on (the drivers
included are always a work in progress)
Speeds up make release substantially, of course.

nor are they the same size.

generations don't try to change any of the values and break the code.

peanuts -- but all work has to start somewhere.

I mirrored from smtpd a little too literally.

(sorry, my other changes were accidentally premature)

Reduces the number of log.c snowflakes by a little, and gives ntpd a
variadic fatal() function to be used later.

remember to set EACCES in bcrypt_checkpass for hash differences.
the higher level crypt_checkpass function will reset errno to EACCES in
all cases, which is probably the right behavior, but this change gives code
working with the lower level functions the correct errno if they care.

what's going on.

guenther suggested using thread time, which actually may improve accuracy
if somebody puts this in a threaded program.

suggested by deraadt@ re: more general MIN/MAX cleanups

This avoids a namespace conflict with Solaris build environments.
discussed with deraadt@ and kettenis@

Switch to local definitions where MAX is needed.
discussed with deraadt@

Nothing is done with the return value from ntp_dns, and it already calls
fatal() on failure.
