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.

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.

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.

e643cede3a uart: add ISR callback mechanism for UART drivers
The peripherals utilizing UART were required to register their own
ISR rountines. This means that all those peripherals drivers need
to know which IRQ line is attached to a UART controller, and all
the other config values required to register a ISR. This causes
scalibility issue as every board and peripherals have to define
those values.

Another reason for this patch is to support virtual serial ports.
Virtual serial ports do not have physical interrupt lines to
attach, and thus would not work.

This patch adds a simple callback mechanism, which calls a function
when UART interrupts are triggered. The low level plumbing still needs
to be done by the peripheral drivers, as these drivers may need to
access low level capability of UART to function correctly. This simply
moves the interrupt setup into the UART drivers themselves. By doing
this, the peripheral drivers do not need to know all the config values
to properly setup the interrupts and attaching the ISR. One drawback
is that this adds to the interrupt latency.

Note that this patch breaks backward compatibility in terms of
setting up interrupt for UART controller. How to use UART is still
the same.

This also addresses the following issues:

() UART driver for Atmel SAM3 currently does not support interrupts.
   So remove the code from vector table. This will be updated when
   there is interrupt support for the driver.
() Corrected some config options for Stellaris UART driver.

This was tested with samples/shell on Arduino 101, and on QEMU
(Cortex-M3 and x86).

06e2b4e129 nanokernel: Change fiber_delayed_start() return type
Instead of returning a 'void *', the nanokernel fiber_delayed_start()
family of routines now return a handle of type nano_thread_id_t.

Consequently, the nanokernel fiber_delayed_start_cancel() family of
routines now accept a parameter of type nano_thread_id_t instead of
'void *'.

The complete list of affected nanokernel routines is:
    fiber_delayed_start()        fiber_delayed_start_cancel()
    fiber_fiber_delayed_start()  fiber_fiber_delayed_start_cancel()
    task_fiber_delayed_start()   task_fiber_delayed_start_cancel()

d9cfbd5a61 interrupts: new static IRQ API
The interrupt API has been redesigned:

- irq_connect() for dynamic interrupts renamed to irq_connect_dynamic().
  It will be used in situations where the new static irq_connect()
  won't work, i.e. the value of arguments can't be computed at build time
- a new API for static interrupts replaces irq_connect(). it is used
  exactly the same way as its dynamic counterpart. The old static irq
  macros will be removed
- Separate stub assembly files are no longer needed as the stubs are now
  generated inline with irq_connect()

ReST documentation updated for the changed API. Some detail about the
IDT in ROM added, and an oblique reference to the internal-only
_irq_handler_set() API removed; we don't talk about internal APIs in
the official documentation.
