Add software PMC support.

New kernel events can be added at various location for sampling or counting.
This will for example allow easy system profiling whatever the processor is
with known tools like pmcstat(8).

Simultaneous usage of software PMC and hardware PMC is possible, for example
looking at the lock acquire failure, page fault while sampling on
instructions.

- Support inlined location in calltree output.
  In case of multiple level of inlining all the locations are flattened.
  Require recent binutils/addr2line (head works or binutils from ports
  with the right $PATH order).
- Multiple fixes in the calltree output (recursion case, ...)
- Fix the calltree top view that previously hide some shared nodes.

Tested with Kcachegrind(kdesdk4)/qcachegrind(head).

Add a flush of the current PMC log buffer before displaying the next top.

As the underlying block is 4KB if the PMC throughput is low the measurement
will be reported on the next tick. pmcstat(8) use the modified flush API to
reclaim current buffer before displaying next top.

Convert pmcstat about using cpuset_t rather than relying on plain 32 bit

ints.  That fixes a first bug where pmcstat wasn't using the old
cpumask_t interface and now also brings the full support for more
than 32 cpus.

While here, make the functions pmcstat_clone_event_descriptor() and
pmcstat_get_cpumask() private to pmcstat.

The problem of assuming cpu dense masks still persists and should be
eventually fixed, as reported by avg.
