Fix minor style issues with excessive whitespace for alignment and
lack of 'static' for the tx_fiber_stack.

Right now the hci-uart samples doesn't really work anywhere else than
nRF5x, so make that the default configuration. Also rename the old
prj.conf to generic.conf to give a generic starting point for creating
configurations for other targets.

In 3 of our UART driver implementations the ISR is exclusively
used and enabled for the RX path. The existing logic was
susceptible to a stall situation where a polled out transmission
would be interrupted by a reception and then the ISR code
would loop forever due to the TX event being signalled (although
the interrupt itself was disabled) causing the ISR to keep
looping for an RX interrupt.

There's no need for this app to use the HCI driver API directly.

It's important that this configuration stays within the limits of the
Arduino 101 nRF51 (which has only 16kB of RAM, unlike most others that
have 32kB).

Since net_buf_get() for the avail_acl_tx FIFO is called in
interrupt context (ISR) it cannot wait, and it will fail
immediately returning NULL if it fails to acquire a buffer.
During LE Secure Connections pairing, when there is a fair
amount of packets coming from the host, the FIFO was running
out of buffers causing the packet to be dropped instead of
forwarding it to the controller.
The number allocated now matches the amount of TX buffers
in the controller, so that normal HCI flow control (from
the Host to the Controller) will kick-in preventing any
buffers from being dropped.

This makes all Bluetooth samples and tests being build with unified
kernel. main() is now executed from init thread and specifying task
for it in mdef file is no longer needed. By default main stack is
1024 bytes and this should be enough for BT samples.

Whenever the writer of a FIFO is an ISR and the reader a fiber it's
important to make sure that we give the chance for other fibers to run
in case the FIFO keeps getting new data from the ISR without ever
running empty.

The bt_driver API was created when Zephyr only had a Bluetooth host
stack, but no controller-side functionality. The only "driver" that
was needed for the host was the HCI driver, and hence "HCI" was
omitted from the name.
With support both for host and controller Zephyr will be getting more
Bluetooth driver types, in particular radio drivers. To prepare for
this, move all HCI drivers to drivers/bluetooth/hci/ and rename the
bt_driver API bt_hci_driver.

Due to the fact that ISRs run at priority 1, the LE_Rand
command was not being rescheduled after CPU sleep to be
able to fill its buffers. By performing all TX (to controller)
work on a fiber, the RNG ISR is able to run and the command
can be executed synchronously in the fiber context.

Add a new sample application in sample/bluetooth/hci-uart
that acts as a bridge between a UART and the BLE Controller.
It receives commands and ACL data in H4 format over the UART
and passes them on to the BLE Controller to be processed.
It also conversely forwards all events and incoming ACL data
generated by the BLE Controller to the UART.
The application uses the hci_raw interface to pipe the data
to and from the BLE Controller and UART.
