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.
