perf tools: Add Intel BTS support
Intel BTS support fits within the new auxtrace infrastructure. Recording is
supporting by identifying the Intel BTS PMU, parsing options and setting up
events.
Decoding is supported by queuing up trace data by thread and then decoding
synchronously delivering synthesized event samples into the session processing
for tools to consume.

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.
