The first implementation will support Intel BTS and
Intel PT.
One itrace buffer is mmapped per perf-events buffer.
If the requested itrace buffer size is zero, which
it will be until further support is added, then
no itrace mmapping is attempted.

One auxtrace buffer is mmapped per perf-events buffer.
If the requested auxtrace buffer size is zero, which
it will be until further support is added, then
no auxtrace mmapping is attempted.

If a file contains AUX area tracing data then always allow
fields 'addr' and 'cpu' to be selected as options for perf
script. This is necessary because AUX area decoding
may synthesize events with that information.

The enhanced thread stack is used by higher layers but still
requires the trace number. The trace number is used to
distinguish discontinuous sections of trace (for example
from Snapshot mode or Sample mode), which cause the thread
stack to be flushed.

Add a facility to log Intel Processor Trace
decoding. The log is intended for debugging
purposes only.
The log file name is "intel_pt.log" and is
