can: Add Linux compatible frame and filter structs

Browse source 
Add new "struct can_frame" which is compatible with Linux so that it
is easier to port socket-can applications from Linux.
Rename existing can_filter to can_msg_filter so that the name will
not conflict with Linux compatible can_filter struct.
