The Perl scripting support for perf trace allows most of a trace event's data to be accessed directly as handler arguments, but not all of it e.g. the less common fields aren't passed in. To give scripts access to the other fields and/or any other data or metadata in the main perf executable that might be useful, a way to access the C data in perf from Perl is needed; this patch uses the Perl XS facility to do it for the common_xxx event fields not passed to handler functions. Context.pm exports three functions to Perl scripts that access fields for the current event by calling back into perf: common_pc(), common_flags() and common_lock_depth(). Support for common_flags() field values was added to Core.pm and a script used to sanity check these and other basic scripting features, check-perf-trace.pl, was also added.
