Fedora needs perl-ExtUtils-Embed for Perl scripting, which also
brings along libperl-devel; note this info for the convenience
of Fedora users.

The common_* functions (e.g. common_pc(), etc) are exported as
common_* but named get_common_*, resulting in unresolved
subroutine errors when executing scripts.
Make the internal and external names match.

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.

Add Perf-Trace-Util Perl module and some scripts that use it.
Core.pm contains Perl code to define and access flag and
symbolic fields. Util.pm contains general-purpose utility
functions.
Also adds some makefile bits to install them in
libexec/perf-core/scripts/perl (or wherever perfexec_instdir
points).
