The kernel API for requesting interrupts and the associated callback
have a somewhat strange behaviour. Requesting an interrupts is done
by calling sys_irqsetpolicy using an interrupt and a given id. This
id can be modified by the sys_irqsetpolicy and must be used for
subsequent calls to sys_irqenable/sys_irqdisable. However upon an
incoming call from the kernel NOTIFY_ARG contains the original value
encoded in a set e.g. if 1 << id == true the interrupt was raised.
We used to load the memory driver above the other modules to allow
the memory driver (ramdisk) to grow. We no longer want or need this
this as we have a working mmc driver.
makes lwip use "unsigned int" instead of "unsigned" since this is
more obvious (i.e. type is not implied).

This files defines two constants which are only used through
sys/syslimits. So they where moved there instead of including the file
and it was removed.

* Also cleanup a bit the makefile.
* Also removing small inconsistency for arm builds where log would be
skipped if doing a make hdboot, but not when cross-compiling.

test69 requires superuser powers to adjust the time. This caused
the test to fail when run as a normal user. The patch adds test69
to the setuid list which will allow regular users to execute it.
Patch contributed by Antoine Leca.
Import the NetBSD rdate command and remove the Minix rdate command.
The default behaviour for both is the same. The NetBSD version adds
options to just display the time, adjust the time using adjtime(),
and set the time without printing the time.
Porting Notes:
- Compiles cleanly out of the box without any warnings
- Path changes from /usr/bin/rdate to /usr/sbin/rdate
- checked pkgsrc for any usages of rdate (none found)
- checked src for any usages of rdate (none found)
Testing:
- all command line options work (tested with time.nist.gov server)
- Native and cross build OK

. inet: silence message about exceptions not being implemented
for select(UDP)
This message generates a lot of noise with openntpd. Hide it unless DEBUG is
turned on.

This also adds the sys_settime() kernel call which allows for the adjusting
of the clock named realtime in the kernel. The existing sys_stime()
function is still needed for a separate job (setting the boottime). The
boottime is set in the readclock driver. The sys_settime() interface is
meant to be flexible and will support both clock_settime() and adjtime()
when adjtime() is implemented later.
settimeofday() was adjusted to use the clock_settime() interface.
One side note discovered during testing: uptime(1) (part of the last(1)),
uses wtmp to determine boottime (not Minix's times(2)). This leads `uptime`
to report odd results when you set the time to a time prior to boottime.
This isn't a new bug introduced by my changes. It's been there for a while.
In order to make it more clear that ticks should be used for timers
and realtime should be used for timestamps / displaying the date/time,
getuptime() was renamed to getticks() and getuptime2() was renamed to
getuptime().
Servers, drivers, libraries, tests, etc that use getuptime()/getuptime2()
have been updated. In instances where a realtime was calculated, the
calculation was changed to use realtime.
System calls clock_getres() and clock_gettime() were added to PM/libc.
Old realtime was used for both timers (where an accurate count of
all ticks is needed) and the system time. In order to implement
adjtime(2), these duties must be separated as changing the time
of day by a small amount shouldn't affect timers in any way nor
should it change the boot time.
Following the naming of the clocks used by clock_gettime(2). The
clock named 'realtime' will represent the best guess at the
current wall clock time, and the clock named 'monotonic' will
represent the absolute time the system has been running.
Use monotonic for timers in kernel and in drivers. Use realtime
for determining time of day, dates, etc.
This commit simply renames realtime to monotonic and adds a new
tick counter named realtime. There are no functional changes in
this commit. It just lays the foundation for future work.
. split user-editable and system-owned files in etc/Makefile
. mtab is a symlink, not a file now; remove it
. force-install of certain system-controlled /etc files from
top Makefile
. rename /etc/make.conf to /etc/mk.conf; and don't set $ARCH;
reduce difference in bsd.own.mk
