Handle starting of advertiser and scanner or initiator when advertiser
is using a different identity than the default identity to generate the

We need to handle this only for the privacy case because the random
address is set in the RPA timeout handler and not from the API.
When privacy is disabled we can return error code from the LE Set Random

generated_dts_board.h is pretty redundant and confusing as a name. Call
it devicetree.h instead.
dts.h would be another option, but DTS stands for "devicetree source"
and is the source code format, so it's a bit confusing too.
The replacement was done by grepping for 'generated_dts_board' and
'GENERATED_DTS_BOARD'.

Under race conditions it is possible that there is no call
to k_sem_give to the waiting k_sem_take in the ull_disable
function.
ull_disable function checks for reference count before
using a mayfly to schedule lll_disable, which in turn
would close requested currently active role event leading
to done event being propogated to ULL. Done event would
then call the set disabled_cb callback when the reference
count is zero, giving the semaphore to the waiting
k_sem_give in the ull_disable.
Under race conditions if the reference count reached zero
after the reference count check and before the disabled_cb
was assigned in the ull_disable function, then there are
chances that a k_sem_give is not called while ull_disable
proceeds to waiting using k_sem_take.

Fix error in calculation of the minimum discardable buffer size. For
the LE Advertising Report the maximum payload is 31 bytes plus
additional data in the event gives an event size of 41 bytes (given that
num_reports is 1). Since this is a meta event we need to include the
sub-event code, plus the event header of 2 bytes. Total of 44 bytes.
This is a regression from afa9c42d75 where we forgot th 1 byte for the

Remove re-using connection objects in disconnected state when creating
directed advertiser or establishing a connection as a central using
direct connection procedure.
This makes the API mores consistent it terms of which connection roles
can be started from the disconnected callback.
This also avoids a central connection object being re-used for a
connection as a peripheral instead and vice versa.
When attempting to create a new connection the API would returning
a valid connection object if there is already an existing connection
object.
This existing connection object could be either in the process of
establishing the connection or already connected.
Returning the connection object in this would give the false impression
that the stack has initiated connection procedure, when in fact it just
returned an existing connection object.
The application has the ability to check for existing connection objects
using the bt_conn_lookup_addr_le API.
Add warning plus comment possible scenarios why the a valid connection
object might exists. Most important is to explain why a valid connection
object exists during the disconnected callback.

Fix controllers address check in cases of controller-based privacy.
When controller has been instructed by the host to use privacy
the controller should look up the peer identity address and generate
an address based on the local IRK. In the case where no match
is found or the local IRK is all zeroes the controller shall use
the fallback address. If the fallback address is not valid the
controller shall return invalid params.
This commit fixes these issues:
- Starting a private advertiser without valid random address set
but a valid local IRK exists. In this case the advertiser should
be able to advertise using the RPA regardless of a valid random
or public address.
- Starting a private advertiser with a fallback to the public
address type or an adveriser using public address does not
check if a valid public address exists. The host cannot
advertise with an all-zero public address.
