Keith Packard 0b90fd5adf samples, tests, boards: Switch main return type from void to int
As both C and C++ standards require applications running under an OS to
return 'int', adapt that for Zephyr to align with those standard. This also
eliminates errors when building with clang when not using -ffreestanding,
and reduces the need for compiler flags to silence warnings for both clang
and gcc.

Most of these changes were automated using coccinelle with the following
script:

@@
@@
- void
+ int
main(...) {
	...
-	return;
+	return 0;
	...
}

Approximately 40 files had to be edited by hand as coccinelle was unable to
fix them.

Bluetooth: Peripheral SC-only
#############################

Overview
********

Similar to the :ref:`Peripheral <ble_peripheral>` sample, except that this
application enables the Secure Connections Only mode, i.e. will only
accept connections that are secured using security level 4 (FIPS).


Requirements
************

* BlueZ running on the host, or
* A board with BLE support

Building and Running
********************

This sample can be found under :zephyr_file:`samples/bluetooth/peripheral_sc_only`
in the Zephyr tree.

See :ref:`bluetooth samples section <bluetooth-samples>` for details.
