6lowpan over BLE should work without solicit node multicast messages
according to RFC7668[1], but that requires Neighbor Solicitation with
Address Registration Option, which is currently not implemented in
either Zephyr or Linux. This is causing the router to fallback to normal
neighbor solicitation based discovery, but the NS frames are being
discarded in the host stack because the solicit node multicast groups
are not registered.
This drops the NET_L2_MULTICAST_SKIP_JOIN_SOLICIT_NODE as a workaround
and adds a TODO about it.

Convert drivers to DEVICE_DEFINE instead of DEVICE_AND_API_INIT

Now that device_api attribute is unmodified at runtime, as well as all
the other attributes, it is possible to switch all device driver

A coccinelle rule is used for this:

Deprecate BT_LE_ADV defines in hci.h that are expected to be used by the
application in the scan received callback to identify the advertising
PDU type. These defines are mixing HCI input parameters and advertising
PDU types. Internally it is acceptable to mix these, but at the API we
should to mix in them.

Deprecate bt_create_conn_le and rename it to in order to add return
code, new arguments and to follow the established naming convention.
Add API for the application to control the scan parameters of the
initiator role. This allows the application more scheduling control
of the initiator in multi-role scenarios. Also provides options to
configure the initiator for LE Coded PHY for long range support.
We deprecate the old way of creating connection to make the name more
consistent with the rest of the API.

Make the channel ops struct const since there really isn't anything
there that needs to change at runtime. The only exception is the L2CAP
shell which was playing with the recv callback, however that can be
fixed by introducing a simple bool variable.
With tests/bluetooth/shell this reduces RAM consumption by 112 bytes
while adding only 16 bytes to flash consumption.

Remove network specific default and max log level setting
and start to use the zephyr logging values for those.
Remove LOG_MODULE_REGISTER() from net_core.h and place the
calls into .c files. This is done in order to avoid weird
compiler errors in some cases and to make the code look similar
as other subsystems.

As the debugging print calls are async, all the strings that might

Instead of one global log level option and one on/off boolean
config option / module, this commit creates one log level option
for each module. This simplifies the logging as it is now possible
to enable different level of debugging output for each network
module individually.
The commit also converts the code to use the new logger
instead of the old sys_log.

This adds a int return to recv callback which can be used to notify the
stack about errors when receiving a packet. In addition to that the user
can return -EINPROGRESS to inform the stack the data will be processed
asynchronously which can be complete by calling
bt_l2cap_chan_recv_complete.

From https://tools.ietf.org/html/rfc7668#section-3.2.2 :

There is no need for 6LN to join the solicited-node multicast address,
