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.

Implement pmc(9) -- An interface to hardware performance monitoring
counters.  These counters do not exist on all CPUs, but where they
do exist, can be used for counting events such as dcache misses that
would otherwise be difficult or impossible to instrument by code
inspection or hardware simulation.

pmc(9) is meant to be a general interface.  Initially, the Intel XScale
counters are the only ones supported.
