After some off-list discussion, revert a number of changes to the DPCPU_DEFINE and VNET_DEFINE macros, as these cause problems for various people working on the affected files. A better long-term solution is still being considered. This reversal may give some modules empty set_pcpu or set_vnet sections, but these are harmless.

Now that all platforms use genclock, shuffle things around slightly for better structure.
Much of this is related to <sys/clock.h>, which should really have been called <sys/calendar.h>, but unless and until we need the name, the repocopy can wait.
In general the kernel does not know about minutes, hours, days, timezones, daylight savings time, leap-years and such. All that is theoretically a matter for userland only.
Parts of kernel code does however care: badly designed filesystems store timestamps in local time and RTC chips almost universally track time in a YY-MM-DD HH:MM:SS format, and sometimes in local timezone instead of UTC. For this we have <sys/clock.h>
<sys/time.h> on the other hand, deals with time_t, timeval, timespec and so on. These know only seconds and fractions thereof.
Move inittodr() and resettodr() prototypes to <sys/time.h>. Retain the names as it is one of the few surviving PDP/VAX references.
Move startrtclock() to <machine/clock.h> on relevant platforms, it is a MD call between machdep.c/clock.c. Remove references to it elsewhere.
Remove a lot of unnecessary <sys/clock.h> includes.
Move the machdep.disable_rtc_set sysctl to subr_rtc.c where it belongs. XXX: should be kern.disable_rtc_set really, it's not MD.

The "free-lance" timer in the i8254 is only used for the speaker these days, so de-generalize the acquire_timer/release_timer api to just deal with speakers.
The new (optional) MD functions are: timer_spkr_acquire() timer_spkr_release() and timer_spkr_setfreq()
the last of which configures the timer to generate a tone of a given frequency, in Hz instead of 1/1193182th of seconds.
Drop entirely timer2 on pc98, it is not used anywhere at all.
Move sysbeep() to kern/tty_cons.c and use the timer_spkr*() if they exist, and do nothing otherwise.
Remove prototypes and empty acquire-/release-timer() and sysbeep() functions from the non-beeping archs.
This eliminate the need for the speaker driver to know about i8254frequency at all. In theory this makes the speaker driver MI, contingent on the timer_spkr_*() functions existing but the driver does not know this yet and still attaches to the ISA bus.
Syscons is more tricky, in one function, sc_tone(), it knows the hz and things are just fine.
In the other function, sc_bell() it seems to get the period from the KDMKTONE ioctl in terms if 1/1193182th second, so we hardcode the 1193182 and leave it at that. It's probably not important.
Change a few other sysbeep() uses which obviously knew that the argument was in terms of i8254 frequency, and leave alone those that look like people thought sysbeep() took frequency in hertz.
This eliminates the knowledge of i8254_freq from all but the actual clock.c code and the prof_machdep.c on amd64 and i386, where I think it would be smart to ask for help from the timecounters anyway [TBD].

Second part of a little cleanup in the calendar/timezone/RTC handling.
Split subr_clock.c in two parts (by repo-copy): subr_clock.c contains generic RTC and calendaric stuff. etc. subr_rtc.c contains the newbus'ified RTC interface.
Centralize the machdep.{adjkerntz,disable_rtc_set,wall_cmos_clock} sysctls and associated variables into subr_clock.c. They are not machine dependent and we have generic code that relies on being present so they are not even optional.

Tweak how the MD code calls the fooclock() methods some. Instead of passing a pointer to an opaque clockframe structure and requiring the MD code to supply CLKF_FOO() macros to extract needed values out of the opaque structure, just pass the needed values directly. In practice this means passing the pair (usermode, pc) to hardclock() and profclock() and passing the boolean (usermode) to hardclock_cpu() and hardclock_process(). Other details: - Axe clockframe and CLKF_FOO() macros on all architectures. Basically, all the archs were taking a trapframe and converting it into a clockframe one way or another. Now they can just extract the PC and usermode values directly out of the trapframe and pass it to fooclock(). - Renamed hardclock_process() to hardclock_cpu() as the latter is more accurate. - On Alpha, we now run profclock() at hz (profhz == hz) rather than at the slower stathz. - On Alpha, for the TurboLaser machines that don't have an 8254 timecounter, call hardclock() directly. This removes an extra conditional check from every clock interrupt on Alpha on the BSP. There is probably room for even further pruning here by changing Alpha to use the simplified timecounter we use on x86 with the lapic timer since we don't get interrupts from the 8254 on Alpha anyway. - On x86, clkintr() shouldn't ever be called now unless using_lapic_timer is false, so add a KASSERT() to that affect and remove a condition to slightly optimize the non-lapic case. - Change prototypeof arm_handler_execute() so that it's first arg is a trapframe pointer rather than a void pointer for clarity. - Use KCOUNT macro in profclock() to lookup the kernel profiling bucket.

Split statclock into statclock and profclock, and made the method for driving statclock based on profhz when profiling is enabled MD, since most platforms don't use this anyway. This removes the need for statclock_process, whose only purpose was to subdivide profhz, and gets the profiling clock running outside of sched_lock on platforms that implement suswintr. Also changed the interface for starting and stopping the profiling clock to do just that, instead of changing the rate of statclock, since they can now be separate.
