Add Cometlake support.

Obtain the number of general counters from CPUID 0xa.

Test cpuid_level in tprof_intel_ncounters().
This function is called before tprof_intel_ident().

KNF. No functional change.

Add two note to the tprof(8)'s manual page.
 - "list" command prints the maximum number of counters that can be used
   simultaneously.

Improve tprof(4)

- Multiple events can now be handled simultaneously.
- Counters should be configured with TPROF_IOC_CONFIGURE_EVENT in advance,
  instead of being configured at TPROF_IOC_START.
- The configured counters can be started and stopped repeatedly by
  PROF_IOC_START/TPROF_IOC_STOP.
- The value of the performance counter can be obtained at any timing as a 64bit
  value with TPROF_IOC_GETCOUNTS.
- Backend common parts are handled in tprof.c as much as possible, and functions
  on the tprof_backend side have been reimplemented to be more primitive.
- The reset value of counter overflows for profiling can now be adjusted.
  It is calculated by default from the CPU clock (speed of cycle counter) and
  TPROF_HZ, but for some events the value may be too large to be sufficient for
  profiling. The event counter can be specified as a ratio to the default or as
  an absolute value when configuring the event counter.
- Due to overall changes, API and ABI have been changed. TPROF_VERSION and
  TPROF_BACKEND_VERSION were updated.

Merge tpfmt(1) into tprof(8). We want to have access to everything with
only one tool. The code is copied mostly as-is, and the functionality is
available via the "analyze" command.

Eg:
	tprof monitor -e llc-misses:k -o myfile.out sleep 20
	tprof analyze < myfile.out

Will move soon, I don't like the reading via stdin.

Revamp tprof.

Rewrite the Intel backend to use the generic PMC interface, which is
available on all Intel CPUs. Synchronize the AMD backend with the new
interface.

The kernel identifies the PMC interface, and gives its id to userland.
Userland then queries the events itself (via cpuid etc). These events
depend on the PMC interface.

The tprof utility is rewritten to allow the user to choose which event
to count (which was not possible until now, the event was hardcoded in
the backend). The command line format is based on usr.bin/pmc, eg:

	tprof -e llc-misses:k -o output sleep 20

The man page is updated too, but the arguments will likely change soon
anyway so it doesn't matter a lot.

The tprof utility has three tables:

	Intel Architectural Version 1
	Intel Skylake/Kabylake
	AMD Family 10h

A CPU can support a combination of tables. For example Kabylake has
Intel-Architectural-Version-1 and its own Intel-Kabylake table.

For now the Intel Skylake/Kabylake table contains only one event, just
to demonstrate that the combination of tables works. Tested on an
Intel Core i5 Kabylake.

The code for AMD Family 10h is taken from the code I had written for
usr.bin/pmc. I haven't tested it yet, but it's the same as pmc(1), so
I guess it works as-is.

The whole thing is written in such a way that (I think) it is not
complicated to add more CPU models, and more architectures (other than
x86).
