This patch adds on-demand wakeup request sending (and re-sendind) when
we are in low-power state. When the controller enters this state it will
send a sleep message after which the host is not allowed to send any
other packets until a wakeup request has been sent and the woken message
received as a response to it. The wakeup requests are re-sent
periodically until a woken message is received.

This patch adds tracking for the uninitialized, initialized and active
states for Three-wire UART. This is needed so we can handle periodic
sending of the Link Establishment messages before reaching active state
and so that we do not try to do any higher level HCI data transmission
before reaching active state.

This patch adds very basic support for the sleep related messages. The
only thing the code does right now is send a wakeup message as soon as
receiving a sleep one, essentially preventing the controller from going
to sleep.
