2178fc5ab3 Bluetooth: L2CAP: Add configuration response handler
Adds L2CAP configuration response protocol definitions to be able handle
response from remote in reaction to issued local request to exchange
MTU. Current optimistic path of configuration initiated from local
assumes to set MTU contract in one iteration.

69882759b8 Bluetooth: L2CAP: Initiate MTU configuration request
Triggers conditionally outgoing configuration request to start exchange
MTU just after incoming PSM connection request was aknowledged by local
host. If local MTU differs from default (672) add MTU option in request,
otherwise send empty configuration meaning default is wanted.

8b1c837e28 Bluetooth: L2CAP: Handle incoming BR/EDR connection request
Enables L2CAP protocol definitions for connection request/response and
use it then to start handle incoming PSM connection request to valid
registered local PSM server. SDP PSM got no security restrictions.
The other PSM connections are validated against link encryption and
availability of SSP feature and if not matched are refused with
security error.

b2647d84b3 Bluetooth: L2CAP: Refactor l2cap core types
Refactors L2CAP core data structures and modifies functions that uses them.
Now we can have separate L2CAP feature channel objects for LE and BR/EDR
transport. This's also a ground for make L2CAP CoC API to be common
for both transports.

cffb92bc63 Bluetooth: L2CAP: Handle information request command on BR/EDR
Adds support to handle incoming L2CAP information request from
remote to get local information about 'extended features' and 'fixed
channels'. For now local stack ensures support for L2CAP BR/EDR
signalling channel.

Moves, specific for BR/EDR transport, register fixed channel handler
to l2cap_br.c file and make it local. Then using it register BR/EDR
signal channel (CID 1) context during channel layer initialization
in 'bt_l2cap_br_init'.

51044bf5f8 Bluetooth: L2CAP: Introduce internal BR/EDR connection L2CAP notifier API
Adds dedicated function informing L2CAP layer about established BR/EDR
connection. Existing 'bt_l2cap_connected()' connection notifier is
refactored to use new API 'bt_l2cap_br_connected()' which is implemented
in l2cap_br.c file.
Currently the new handler is just stub since proper internals of
BR/EDR L2CAP signal channel management are not yet implemented
in l2cap_br.c file.

Moves initialization of signal buffer for BR/EDR transport to
l2cap_br.c unit and removes existing references to signal buffer in
l2cap.c file to prevent compiler complains.

b9d13664ab Bluetooth: Create protocol-specific outgoing ACL buffer pools
With this split we get better control of the buffer sizes and counts.
We also anyway will need a fragments pool so a simple generic ACL_OUT
pool doesn't make sense anymore. The related Kconfig options for that
have been removed.
