Implement support for the USB488 defined READ_STATUS_BYTE ioctl (1/5)
and SRQ notifications with fasync (2/5) and poll/select (3/5) in order
to be able to synchronize with variable duration instrument
operations.

Add ioctls for other USB488 requests: REN_CONTROL, GOTO_LOCAL and
LOCAL_LOCKOUT. (4/5)

Add convenience ioctl to return all device capabilities (5/5)
