Fix double prepare overhead considered in scheduling
extended, periodic and ISO broadcast radio events when using
LOW LAT variant.
ticks_slot maintained in ticker includes the overhead, the
ticks_slot stored in role/state context exclude the overhead
hence take care to include ticks_slot_overhead when value is
used from context and not when value used from ticker nodes.
Add jitter due to ticker resolution unit between scheduled
radio events. This will allow the synchronizing side too to
not overlap due to ticker resolution related jitter.

BAP would always set up the ISO data path in both directions,
even for unidirectional CIS. This meant that in the
unconfigured direction, the data path configuration data
would all be 0, which causes issues on some controllers.
The new refactored approach implemented by this commit
will always ensure that the data path is setup correctly,
and that we only set the data path in one direction for
unidirectional CIS. The unset path will use the default
ISO path of HCI and transparant format, which should always
be allowed by a controller.
This is building on the requirement in BAP that all streams in
a unicast group shall be QoS configured at the same time. This
ensures that before any streams in the CIG has been connected,
they have all been configured.

When the central aborts the CIS setup during the CIS Creation
procedure after it has accepted the CIS request, the peripheral
will receive the HCI LE CIS Established event with an error code.
It does not receive a disconnection event.

Add callbacks to the stream objects that reflects the
state of the isochronous channel. The connected callback
is called when the isochronous channel is connected, and
similarly the disconnected callback is called when it is
disconnected.
There is a special case for unicast, where if the ACL
disconnects first, then we won't get a ISO disconnect
callback. It should be assumed that the isochronous channel
is no longer valid when the BAP stream enters the idle state,
i.e. when the "released" callback is called.
The purpose of the new callbacks is to provide additional
information to the application. Especially the unicast client
can use this to determine when the stream_start function
can be called again, as there can only ever be 1 outstanding
CIS connection request at a time, but there can be multiple
GATT requests.

Bluetooth Mesh Protocol 1.1 is backward compatible with Bluetooth Mesh
Profile 1.0.1, therefore the stack can still be qualified for 1.0.1 if
needed. But explicit support for both versions requires additional
maintenance efforts and doubles the CI time. To make the stack
qualifiable for 1.0.1, the one needs to remove Private Beacons reception
and compile out SHA256 algorithm support.
What is changed:
- Removed `CONFIG_BT_MESH_V1d1` option.
- Removed `transport_legacy.c` which was using 1.0.1 implementation. The
new transport layer has new SaR logic that should still be possible to
qualify for 1.0.1.
- Removed the legacy transport Kconfig options. They are superseded by
the new transport Kconfig options.
- Tester app: `overlay-mesh-v1d1.conf` is merged into
`overlay-mesh.conf`.
- Removed BabbleSim tests for 1.0.1.
- Updated documentation.

When using the auto discover CCC, and the function is called
more than once with the same parameters before the previous
discovery has completed, then that may cause issues when we
reset the parameters when we get the response.
This commit adds a small check for the callback function
which is only set to the specified function when the
discovery is in progress. This way we can return an error
if the application calls bt_gatt_subscribe multiple times
before the previous discovery has completed, rather
than asserting.

Previously it was not always possible to prepend the header.
It was not possible if the application neglected to reserve the space
for headers. This is bad because it forces a buffer segment allocation
even if the buffer had enough room for the headers. E.g. a payload of 10
bytes in a netbuf of 30 bytes would have been segmented.
We now explicitly reject the buffer if it does not have the headroom.
This allows us to do a nice thing; simplify L2CAP segmentation.
We convert the SDU from the application into a PDU payload, by
prepending the SDU header, i.e. the SDU length in the original buffer.
This PDU payload is ready to be chunked into PDUs without having to keep
track of where in the SDU we are. This has the effect of removing a
bunch of logic in the segmentation machine.
