perf tools: Add infrastructure for PMU specific configuration
This patch adds PMU driver specific configuration to the parser infrastructure by preceding any term with the '@' letter. As such doing something like: perf record -e some_event/@cfg1,@cfg2=config/ ... will see 'cfg1' and 'cfg2=config' being added to the list of evsel config terms. Token 'cfg1' and 'cfg2=config' are not processed in user space and are meant to be interpreted by the PMU driver. First the lexer/parser are supplemented with the required definitions to recognise the driver specific configuration. From there they are simply added to the list of event terms. The bulk of the work is done in function "parse_events_add_pmu()" where driver config event terms are added to a new list of driver config terms, which in turn spliced with the event's new driver configuration list.
