Johan Hedberg e3e91d3280 Bluetooth: Add name member to HCI driver struct
This is more of a convenience to let the driver identify itself in
debug logs and the monitor protocol.

Johan Hedberg 4488fc6cab Bluetooth: Move HCI device bus information to the driver
The bus that we notify over the monitor protocol is really driver
specific, so let each driver specify their bus type.

Johan Hedberg 30601c09bb Bluetooth: Refactor buffer handling for non-host managed buffers
So far the assumption has been that the host stack manages all
incoming and outgoing buffers. For the incoming buffers (from the
controller) this has required hci_core.c to manage its own pools and
do the host flow control. This setup makes perfect sense for an
architecture where the controller resides remotely on a different CPU
& address space (i.e. the "traditional" HCI transport case).

When the stack runs on a system where the controller resides in the
same address space this setup doesn't work that well. In such a
scenario the incoming buffers are ideally created as low down in the
stack as possible (i.e. below HCI), which means that the current
hci_core.c cannot be responsible for managing their pools.

To allow for both types of architectures this patch introduces a new
BLUETOOTH_HOST_BUFFERS Kconfig option that can be selected to say that
host-side management is desired, or deselected to say that the
controller (residing in the same address space) takes care of managing
the incoming buffers.

So far the incoming buffer types were identified by hci_core.c by
looking at their "free pool" pointers, however as soon as the pools
are allowed to be somewhere else this doesn't work. To solve this we
now require a minimum user data size for all Bluetooth buffers and use
that to store the buffer type.

Adds extern "C" { } blocks to header files so that they can be

Johan Hedberg 1f6841c9c1 Bluetooth: Convert driver header info to hidden Kconfig options
We know the needed values at build-time, so there's no point in having
a runtime mechanism of accessing them in the code. Having the values
as defines makes it e.g. possible to use them as input for defining
the size of buffer pools.

Johan Hedberg 4b433d4fa6 Bluetooth: Differentiate send/recv of needed driver headroom
The space that the HCI driver needs to reserve for its own use is not
necessarily symmetrical. E.g. even with the current H4 driver we only
need to reserve space for sending data but not for receiving it.
Keeping track of these values independently enables more efficient use
of the buffers.

Johan Hedberg 5f4daa1551 Bluetooth: Merge send_acl/cmd back to a single callback
Now that we have the buffer type enum as part of the HCI driver API we
can take advantage of it to pass the buffer type information and not
have to have two separate callbacks.

Johan Hedberg ff2d104105 Bluetooth: Move buffer type enum to driver.h
Since the buffer type is essentially a HCI driver - HCI core
communication detail the appropriate place for it is driver.h. At the
same time remove the unnecessary and slightly confusing BT_DUMMY type.
