[magma] Add device query fudge method
This change adds a magma_device_query_fudge method to the magma
protocol, allowing direct use of mapping IDs. It also allows
use of guest-allocated buffers.
This change also expands the protocol README file to document
how each fudge method differs from its standard counterpart.
