Johan Hedberg 2975ca0754 Bluetooth: Kconfig: Rename CONFIG_BLUETOOTH_* to CONFIG_BT_*
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.

Replace the existing Apache 2.0 boilerplate header with an SPDX tag
throughout the zephyr code tree. This patch was generated via a
script run over the master branch.

Also updated doc/porting/application.rst that had a dependency on

Manually updated subsys/logging/sys_log.c that had a malformed
header in the original file.  Also cleanup several cases that already
had a SPDX tag and we either got a duplicate or missed updating.

Applies on L2CAP channel object security requirement member and
implements on BR/EDR transport basic security cases during incoming
CoC connection request. Since channel security requirements can involve
sending 2 separate connection responses with proper results depending on
context path, there's a need to store L2CAP signaling identifier set in
original connection request to be restored later to help match proper
response context.

Arkadiusz Lichwa d5a07edde0 Bluetooth: L2CAP: Refactor channel context by ident
Moves 'ident' member so far included in bt_l2cap_le_chan context only
to common bt_l2cap_chan context. The change is driven by sharing ability
to store/restore 'ident' on both transports and makes use of it only if
CoC is configured. For default configuration there's channel addition
helper to be used internally by dedicated macros managing channel
objects enlisted in connection tracker list.
The common member is used in matching outstanding connection responses
on LE and to prepare a ground for BR/EDR transport context when
there'll be a need to match response to original incoming connection
request after in-between security changes that can happen.

  'The value of this timer is implementation-dependent but the minimum
   initial value is 1 second and the maximum initial value is 60
   seconds. One RTX timer shall exist for each outstanding signaling
   request, including each Echo Request. The timer disappears on the
   final expiration, when the response is received, or the physical
   link is lost.'

Note: As for the actual interval used they are based on the values used
in Linux but in case of disconnect the minimum of 1 seconds was used
to follow the text above.

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.

Luiz Augusto von Dentz 7d2d2838fb Bluetooth: L2CAP: Implement segmentation for incoming packets
If the SDU length is bigger than the amount data received in the first
packet it means it will be segmented in 2 or more packet until the SDU
is completed.

Since the MTU required by the upper layer could be much bigger than the
ACL buffer the code now request a buffer to reassemble the SDU.
