Remove the kernel PMC code. Sent yesterday on tech-kern@.

This change:

* Removes "options PERFCTRS", the associated includes, and the associated
ifdefs. In doing so, it removes several XXXSMPs in the MI code, which is
good.

* Removes the PMC code of ARM XSCALE.

* Removes all the pmc.h files. They were all empty, except for ARM XSCALE.

* Reorders the x86 PMC code not to rely on the legacy pmc.h file. The
definitions are put in sysarch.h.

* Removes the kern/sys_pmc.c file, and along with it, the sys_pmc_control
and sys_pmc_get_info syscalls. They are marked as OBSOL in kern,
netbsd32 and rump.

* Removes the pmc_evid_t and pmc_ctr_t types.

* Removes all the associated man pages. The sets are marked as obsolete.

- All device major numbers must be listed up in port dependent majors.<arch>

- Added the new naming convention.
The name of the device switch must be <prefix>_[bc]devsw for auto-generation

- The backward compatibility of loading block/character device
switch by LKM framework is broken. This is necessary to convert
from block/character device major to device name in runtime and vice versa.

- The restriction to assign device major by LKM is completely removed.
We don't need to reserve LKM entries for dynamic loading of device switch.

- In compile time, device major numbers list is packed into the kernel and
the LKM framework will refer it to assign device major number dynamically.

- create more helper macros:
. cdev__xyz_init(c,n), such as cdev__ocri_init() for
/* open, close, read, ioctl */, etc.
. cdev__xRy_init(c,n), where nullop is used instead of enodev to dummy out
method `R' and the comments now read /* xxx (read) yyy */ instead
. cdev__xyz_t_init(c,n,t) - as per cdev__xyz_init, but sets d_type = t
as well

- use seltrue instead of dev_noimpl(poll,*), as (IIRC) cdevsw.d_poll should
always DTRT WRT returning a valid result. (a few devices previously
incorrectly returned ENODEV)

- use dev_noimpl(stop,enodev) instead of dev_noimpl(stop,nullop) if tty
== 0, because it doesn't matter if dev_type_stop isn't implemented in that
case, and it allows the use of the cdev__xyz_init macros. certain ports
(sparc,sparc64,x68k) used the nullop method for dev_type_stop in a few
drivers, whereas everything else uses enodev

- ensure that the comments are accurate WRT the behaviour of a given entry

Add getlabelusesmbr(), as proposed in
http://mail-index.netbsd.org/tech-userlevel/2011/08/25/msg005404.html
This is used by disk tools such as disklabel(8) to dynamically decide is
the undelyling platform uses a disklabel-in-mbr-partition or not
(instead of using a compile-time list of ports).
getlabelusesmbr() reads the sysctl kern.labelusesmbr, takes its value from the
machdep #define LABELUSESMBR.
For evbmips, make LABELUSESMBR 1 if the platform uses pmon
as bootloader, and 0 (the previous value) otherwise.

merge ktrace-lwp.

Make disklabel(8) and fdisk(8) into "host tools " last step: build
and install ${TOOLDIR}/bin/${MACHINE_GNU_PLATFORM}-disklabel,
${TOOLDIR}/bin/${MACHINE_GNU_PLATFORM}-fdisk by "reaching over" to
the sources in ${NETBSDSRCDIR}/sbin/{disklabel fdisk}/.

To avoid clashes with a build-host's header files, especially on
*BSD, the host-tools versions of fdisk and disklabel search for
#includes such as disklabel.h, disklabel_acorn.h, disklabel_gpt.h,
and bootinfo.h in a new #includes namespace, nbinclude/. That is,
they #include <nbinclude/sys/disklabel.h>, <nbinclude/machine/disklabel.h>,
<nbinclude/sparc64/disklabel.h>, instead of <sys/disklabel.h> and
such. I have also updated the system headers to #include from
nbinclude/-space when HAVE_NBTOOL_CONFIG_H is #defined.
