Add support for reading from the AUX area tracing mmap and synthesizing AUX area tracing events. This patch introduces an abstraction for recording AUX area data. Recording is initialized by auxtrace_record__init() which is a weak function to be implemented by the architecture to provide recording callbacks. Recording is mainly handled by auxtrace_mmap__read() and perf_event__synthesize_auxtrace() but there are callbacks for miscellaneous needs including validating and processing user options, populating private data in auxtrace_info_event, and freeing the structure when finished.
