Add getfd and closefd monitor commands
Add monitor commands to support passing file descriptors via
SCM_RIGHTS.
getfd assigns the passed file descriptor a name for use with other
monitor commands.
closefd allows passed file descriptors to be closed. If a monitor
command actually uses a named file descriptor, closefd will not be
required.
