Avoiding segmentation in the GATT-based Mesh Proxy protocol requires
having an RX buffer length of at least 77. We could round it up to 80
since there's otherwise wasted space, however there's also
BT_HCI_RESERVE to consider, so to avoid pushing over the 4-byte
boundary for certain HCI drivers just leave the size at 77.

The CONFIG_BT_WAIT_NOP define is used only by
zephyr/subsys/bluetooth/host/hci_core.c.
It is also the only config in drivers/bluetooth that is in use when
BT_CONTROLLER is enabled. Moving it into the bluetooth subsystem
allows us to restructure the drivers/kconfig code such that the entire
Bluetooth driver menu option is omitted when the BT_CONTROLLER is
enabled.
Moving it will also mean that all configs in drivers/bluetooth will
now be related to configuring the source code in drivers/bluetooth.

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.

There are two kinds of HCI implementations. Bluetooth drivers in
drivers/bluetooth that implement HCI by using a wired serial
transport layer to talk to an external controller chip. And a
bluetooth controller in subsys/bluetooth/controller that directly
talks to an internal on-chip controller node.
Currently, when the the subsys/bluetooth/controller is used there
still exists exposed to the user a bluetooth driver configuration
menu, even though no external bluetooth driver is in use. This is due
to a dependency on certain configs in driver/bluetooth that are needed
even though no external controller is used.
This patch moves one of these configs, BLUETOOTH_HCI_RESERVE, from
drivers/bluetooth/hci/Kconfig to subsys/bluetooth/host/Kconfig such
that eventually we can omit the entire Bluetooth driver menu option.
This re-organization does not change when the config can be enabled.

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)

L2CAP Dynamic Channel feature uses the global connection Tx
pool for segmentation either when there is no free buffers
in the original application pool or when the original data
buffer has no headroom to add L2CAP headers.
This eliminates the need for a dedicated fallback pool for
Dynamic Channel segmentation.

It's not valid for a peer to send another request before getting the
response to a previous one, or to send another indication without
getting the confirmation to a previous one. Take advantage of the
recently introduced TX callback to track when it's ok to accept these
ATT PDUs again.
The HCI USB transport has a potential issue here since a race
condition can occur between the ACL data and HCI event endpoints,
leading to dropping data when in fact both peers were behaving
correctly. To avoid hitting this issue, disable the flow enforcement
by default on the qemu targets that commonly use a USB-based
controller on the host OS.
