Adrian Hunter 5efb1d5489 perf tools: Take Intel PT into use 
To record an AUX area, the weak function auxtrace_record__init() must be
implemented.

Equally to decode an AUX area, the AUX area tracing type must be added
to the perf_event__process_auxtrace_info() function.

This patch makes those two changes plus hooks up default config for the
intel_pt PMU.  Also some brief documentation is provided for using the
tools with intel_pt.
