Perl module to get caller return OP address and Perl interpreter context

Devel::Callsite module provides subroutines to get the caller return OP address and perl interpreter context.

The callsite() function returns the OP address of the caller, a number, one level up from where it was called. It's useful for functions that need to uniquely know where they were called, such as Every::every(); see Every. Or it can be used to pinpoint a location with finer granularity than a line number (see http://www.perlmonks.com/?node_id=987268). In conjunction with an OP tree disassembly you can know exactly where the caller is located in the Perl source.

The context() function returns the interpreter context as a number. This is a fairly unique number together with the call site.
