Port debug command

[marinier]

Several related commits below. Note that this adds a command that accesses stuff hidden behind a #define for debugging. Not clear if we really want to port this if csoar doesn't unconditionally include it in the code.

Note that the last commit also does some epmem stuff that should already be ported.

Not sure, but this may also be related. But I think this is done completely differently in jsoar, so it may be irrelevant.
