Greg Clayton fc5dd29ef7 Always return a valid answer for qMemoryRegionInfo if the packet is supported.
We will return a valid range when possible and omit the "permissions" key
when the memory is not readable, writeable or executeable. This will help us
know the difference between an error back from this packet and unsupported,
from just "this address isn't in a valid region".
