This is a work-in-progress replacement for PEDA. I was originally just going to use the GEF code from Hugsy but then I went a bit overboard.

In particular, it's designed to be fast*, failure-tolerant**, and eventually portable to Python27/Python3 as well as GDB/LLDB.

Currently it works on GDB with Python3.

* Lots of use of gdb.event to manage cache lifetimes.
** Automatic exploration of process maps when you're doing e.g. remote debugging of a QEMU user stub and /proc/$$/pids is broken for ${reasons}.
