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".

from a process and hooked it up to the new packet that was recently added
to our GDB remote executable named debugserver. Now Process has the following
new calls:
virtual Error
Process::GetMemoryRegionInfo (lldb::addr_t load_addr, MemoryRegionInfo &range_info);
virtual uint32_t
GetLoadAddressPermissions (lldb::addr_t load_addr);
Only the first one needs to be implemented by subclasses that can add this
support.
Cleaned up the way the new packet was implemented in debugserver to be more
useful as an API inside debugserver. Also found an error where finding a region
for an address actually will pick up the next region that follows the address
in the query so we also need ot make sure that the address we requested the
region for falls into the region that gets returned.

Add a more general purpose qMemoryRegionInfo packet which can
describe various attributes about a memory region. Currently it
will return the start address, size, and permissions (read, write,
executable) for the memory region. It may be possible to add
additional attributes in the future such as whether the region is
designated as stack memory or jitted code a la vmmap.
I still haven't implemented the lldb side of the code to use this
packet yet so there may be unexpected behavior - but the basic implementation looks
about right. I'll hook it up to lldb soon and fix any problems that crop up.
