With the introduction of privacy, the system workqueue is now being
linked into the image, growing the RAM footprint considerably.
In order for the sample to fit in QFAA and QFAB variants of the nRF51
(16KB of RAM) we reduce the workqueue stack size to 512 since the RPA
update mechanism doesn't use more than 340 bytes and we stick to 16
connections maximum.

The idle stack already defaults to 256. The ISR stack size of 640 was
intended to make the app fit on 16k nRF51 variants and is now the
default, i.e. it doesn't need to be explicitly set anymore.

The following readings were obtained after running the peripheral and
central_hr apps in qemu combined with the controller (hci_uart) on nRF51
and nRF52:
Main Stack 380
Idle Stack: 68
ISR stack: 532
Controller RX Stack: 388
HCI TX Stack: 516
The numbers set in this change provide a safety margin from the ones
measured empirically.

HCI ECC commands are causing freezes in the controller build. Until
further investigation is done disable them to avoid issues when running
the controller standalone.

From stack_analyze function, used isr stack is 368 bytes
with the controller build, main stack is 288 bytes and idle
stack is 56 bytes. Hence, configuring sizes of 512, 512,
and 256 bytes for isr, main and idle stacks respectively.
Increased max connections from 16 to 20 utilizing the RAM
free from the reduced stack sizes.

Implement the 2 HCI commands that provide ECC public key
and shared secret generation:
- LE Read Local P-256 Public Key
- LE Generate DHKey

Currently the ideal buffer counts for a controller-only build are 6 RX
buffers and 7 TX buffers: ATT_MTU of 158 bytes can be sent in one
connection interval of 6 tx/rx -es wherein connection interval is
7.5ms

Restructure the Bluetooth options more logically.
- Both host and controller are now behind the same high level
CONFIG_BLUETOOTH.
- Selecting controller support disables other HCI driver selection, so
the controller isn't in the same list as HCI drivers any more.
- Under the top-level there's a "Custom stack" option, which when
enabled opens up the option of choosing CONFIG_NBLE.
There are various other cleanups and simplifications in this patch as
well, since splitting these up would have been fairly tricky while
making sure all test cases still build.

When building Zephyr in the controller-only configuration,
assertions that happen in the Link Layer code are not visible
to the Host which is running on another HCI and connected via
UART or USB to it. This patch allows the Controller code
to output the assertion line number when in such a configuration,
allowing the Host to view the event to help debugging.
The event format used is temporary and will be replaced by a
standardized Vendor Specific specification to come at a later
time.

The convention for Zephyr sample names is to use _ instead of - for
delimiting words.
