Sync with HEAD, resolve a few conflicts

Clean up initialization of com_regs structure, in preparation for
some additional changers.

Allow algor kernels to be built under either algor/algor64 or
evbmips-el/evbmips64-el.  Note that MAXMAPARITITONS and majors numbers
differ between the two ports which is why two kernels are still needed.

#include <sys/bus.h> instead of <machine/bus.h>.

- Use uvm_lwp_setuarea() instead of directly setting address to lwp_t::l_addr.
- Replace most remaining uses of l_addr with uvm_lwp_getuarea() or lwp_getpcb().
- Amend assembly in ports where it accesses PCB via struct user.
- Rename L_ADDR to L_PCB in few places.  Reduce sys/user.h inclusions.

Split device_t and softc for all com(4) devices (well, everything that
uses a com_softc backend).  Use proper types and ansify where appropriate.

Use pmf_device_register1() instead of shutdownhook_establish() to
register com_cleanup() as the shutdown hook.

Add a generic suspend routine.  Suspend and resume com@isa.

Protect against dereferencing a NULL softc in comioctl().

Destroy both a mutex and a callout in com_detach().

Cosmetic: use aprint_*_dev().  Use PMF_FN_ARGS, PMF_FN_PROTO.

Add an option COM_REGMAP to allow com(4) to use an array of register indices.
This allows us to convert aucom to just another com attachment, and cleanup
some code in the com_arbus.c.

Additionally, we use a common com_cleanup routine rather than having a
zillion copies of it in the attachment points.

This has been tested on a number architectures, and it has been shown to get
close to comparable performance when COM_REGMAP is defined, and comparable
when it is not defined.

Approved by core@.  Fixes PR port-evbmips/32362.

Undo the undo.  Restore COM_INIT_REGS handling.

Undo the change to use COM_INIT_REGS, and instead use backwards compat
support.  For com_arbus and com_aubus, we have to set a new flag, COM_HW_REGMAP
to indicate that we have special mapping considerations so that com_attach_subr
doesn't clobber our register map.

Use common com_cleanup.

Another com_mainbus.  Again, only compile tested.

Catch up to -current.

sync kqueue with -current; this includes merge of gehenna-devsw branch,
merge of i386 MP branch, and part of autoconf rototil work

Fix script-o's in last.

Use CFATTACH_DECL().

Declare all cfattach structures const.

Rather than referencing the cfdriver directly in the cfdata entries,
instead use a string naming the driver.  The cfdriver is then looked
up in a list which is built at run-time.

Yet more interrupt cleanup -- the platform mater interrupt establish
function now just takes an "irq", which is an index into the irqmap
table for that platform.

Rewrite the interrupt handling code:
- Compute the number of CPU pipeline cycles per second using the
  mc146818.
- Use the COMPARE interrupt for the hardclock interrupt.
- Collapse all interrupt priorities into a single priority, and use
  the CPU interrupt inputs to determine the interrupt source (local
  device, PCI device, ISA device, etc.)

This allows us to have interrupt sharing.

Add support for the Algorithmics P-4032 board.  This is totally
untested, since I have no P-4032 board, but it's no worse than
the current situation, which is "totally non-working P-4032
support in the ARC port, of all places".
