Add gdb python scripts as kernel debugging helpers

Another refresh of this feature series. Changes since v8:
 - Ignore byte-compiled python files [Daniel Thompson]
 - rebase over recent Linux version, resolving a trivial conflict

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.

Note that there is apparently some issue with gdb 7.8 and newer that
prevents lx-symbols from working here [1]. 7.7 is still fine, though.
