Introduce a separate buffer pool for events which the HCI driver
considers discardable. Examples of such events could be e.g.
Advertising Reports. The benefit of having such a pool means that the
if there is a heavy inflow of such events it will not cause the
allocation for other critical events to block and may even eliminate
deadlocks in some cases.
Also update all mesh samples not to specify explicit RX buffer counts
anymore. Instead, create appropriate defaults in Kconfig so that we
only need to override this in the app for cases like the bbc:microbit
with limited memory.

Enable BT_SETTINGS and remove any custom flash access used for the
sequence number. We do settings_load() before bt_mesh_provision() and
use the return value from the latter to identity that settings_load()
had recoved a full configuration.

The API name space for Bluetooth is bt_* and BT_* so it makes sense to
align the Kconfig name space with this. The additional benefit is that
this also makes the names shorter. It is also in line with what Linux
uses for Bluetooth Kconfig entries.
Some Bluetooth-related Networking Kconfig defines are renamed as well
in order to be consistent, such as NET_L2_BLUETOOTH.

Add an initial implementation for the Bluetooth Mesh Profile
Specification. The main code resides in subsys/bluetooth/host/mesh and
the public API can be found in include/bluetooth/mesh.h. There are a
couple of samples provided as well under samples/bluetooth and
tests/bluetooth.
The implementation covers all layers of the Bluetooth Mesh stack and
most optional features as well. The following is a list of some of
these features and the c-files where the implementation can be found:
- GATT & Advertising bearers (proxy.c & adv.c)
- Network Layer (net.c)
- Lower and Upper Transport Layers (transport.c)
- Access Layer (access.c)
- Foundation Models, Server role (health.c & cfg.c)
- Both PB-ADV and PB-GATT based provisioning (prov.c)
- Low Power Node support (lpn.c)
- Relay support (net.c)
- GATT Proxy (proxy.c)
Notable features that are *not* part of the implementation:
- Friend support (initial bits are in place in friend.c)
- Provisioner support (low-value for typical Zephyr devices)
- GATT Client (low-value for typical Zephyr devices)
