add "humility dump" support for in situ dumping (#313)

This work adds the necessary "humility dump" support for in situ
dumping, whereby dump contents are deposited into auxiliary memory
within Hubris itself.  This also includes the necessary support to
both simulate dumping (where the dump agent is skipped entirely) and
to emulate dumping (where Humility acts as the dumper, depositing
Hubris contents into the agent-directed memory locations).
