Devfind revision phase 1, cleaning out some legacy stuff
- Eliminate the cached device_t::m_region pointer and its region() getter method. Devices that need to bind to a region with the same tag should use optional/required_memory_region or optional/required_region_ptr with DEVICE_SELF as the subtag; this improves error checking. (DEVICE_SELF has been moved to device.h for greater visibility in the source.) - Allow required/optional_region_ptr to specify a specific length which must match that of the region found. - Implement finder_base::finder_tag() getter for diagnostic purposes. - Perform some (not very efficient) validity checks on memory region finders instead of allowing them to automatically pass. - Privatize device_memory_interface::m_addrspace.
