If we're out of buffers the UART driver would previously loose sync of
where the packet boundaries go, because it was using the buffer itself
to store and parse the HCI packet headers. This patch modifies the
UART driver to use stack variable for initial header parsing, thereby
being able to always determine how many remaining bytes there are and
cleanly discard the bytes until the beginning of the next packet.

If we get an invalid packet type here the buf pointer will be NULL.
Going to the cleanup section at the end of the function would trigger
a bt_but_put() call which would cause a NULL pointer access. Directly
returning from the function is the right thing to do instead.

We may soon want to have a _wait() variant of bt_buf_get, so to avoid
the number of 'get' function growing too large consolidate the
existing get() and get_reserve() functions into a single one. The new
consolidated function also takes the type as input parameter so that
we know this from the very start and thereby plan for the split into
multiple buffer pools.

We'll soon want to have dedicated pools for outgoing and incoming ACL
data. To know from which pool to get and put the buffers each buffer
should contain enough information to distinguish the two types. This
patch splits the old BT_ACL type into two new BT_ACL_IN & BT_ACL_OUT
types.

This patch adds a simple HCI UART (H4) driver that currently maps to
the second UART in the system. The main intention is to use this
together with qemu for accessing the Bluetooth controller available on
the host OS side.
The H4 HCI transport protocol is perhaps the simplest of the standard
HCI transports. It consists of a single byte in the beginning of each
packet which indicates the type of the packet: HCI event, HCI command,
ACL data, or SCO data (which we don't use at the moment).

Serial console handler when registered allows to interact with serial
line. It can either execute callback from ISR or defer execution to
fiber or task. This will be used in Bluetooth development for tests and
