kevent: Add precision and abstimer flags for EVFILT_TIMER

Add timer precision flags NOTE_SECONDS, NOTE_MSECONDS, NOTE_USECONDS
and NOTE_NSECONDS for EVFILT_TIMER. Also, add an initial implementation
of NOTE_ABSTIME timers.

Similar kevent(2) flags exist on FreeBSD, NetBSD and XNU.

MAXCOMLEN is no longer needed in these programs, so remove the annotation

it this was the least requirement.

sys/param.h is only needed for MAXCOMLEN, but a few header files
which must be manually included in userland were missing

Display struct event more like other structs: show all members and use cpp
define names. Use the mksubr infrastructure for EVFILT_*,
EV_*, and (with some kludging) NOTE_* values. If EV_ERROR is set,
include the errno string for the data member.

Also, do MSG_* parsing on the msg_flags member of struct msghdr.

isatty() is used by stdio to determine the buffering mode. Add a F_ISATTY

The first argument to socket/socketpair is an address family, not a protocol
family. (sysctl(3) is practically the only place where PF_* is correct)

Eliminate a gcc warnings by not #defining _KERNEL when pulling in
<sys/socket.h>: it doesn't expose anything kdump cares about.
Also, COMPAT_43 is dead

Convert syscall argument handling from a giant switch to a giant table.
While at it, use formatters for fds, counts, ids of all types, and "small
buffer sizes" that always show them in decimal, while paths, pointers, and
"big buffer sizes" get formatters that always show them in hex. The -d
option only affects args when the -n option is used or for unknown syscalls,
as well as syscall return values, and unrecognized ioctls.
