Add gdb python scripts as kernel debugging helpers

Version 5 comes with the following changes:
 - moved tutorial into Documentation/gdb-kernel-debugging.txt
 - improved caching of gdb.Type objects, ensure they are in sync with
   currently loaded symbols
 - added new functions and commands
    - lx_module -- Find module by name and return the module variable
    - lx_modvar -- Return global variable of a module
    - lx-lsmod -- List currently loaded modules

See http://lkml.indiana.edu/hypermail/linux/kernel/1210.0/015... for
the original description and

    git://git.kiszka.org/linux.git queues/gdb-scripts

for the latest version.
