perl module for DWARF debug info parsing

I've made perl binding of my c++ dwarf dumper. Supports 64/32 bit, no DWO, don't sure if it can load arbitrary object files but at least can parse LKM - I even added relocations processing

Maybe one day I'll have the courage to write documentation for it, so for now just several samples of using it:

• script to dump enums
• script to find all functions having arguments with pointer or reference to some named structure
• script to find and dump structures fields
• script to find all classes with VTBL and dump them

So now I have in perl full set of modules to disasm/analyse elf files:

• Elf::Reader
• Disasm::Arm64
• Disasm::Mips
