98321c61fb bluetooth: host: Allow concurrent advertising with multiple ids
The HCI specification creates additional complexity to allow this
configuration:
 - When a connection gets established, we need to know which
   identity the HCI_LE_Connection_Complete event corresponds to.
 - The identity is a property of the advertising set.
   Therefore we need the advertising handle.
 - The advertising handle is part of the
   HCI_LE_Advertising_Set_Terminated event and is not part of
   the HCI_LE_Connection_Complete event. Therefore
   the information of both events needs to be combined.

By spec the LE_Connection_Complete comes first. Therefore we cache
this event until the identity is available.
The event is only cached when a connection gets established as
that is the only case where we need to resolve the identity.

As the caching requires more resources, it is only enabled if the
application requires multiple advertising sets and multiple
identities.

The host maps the HCI_LE_Advertising_Set_Terminated event with
the HCI_LE_Connection_Complete event by comparing the connection
handles.

8a55e04e23 Bluetooth: host: Prevent bt_rand calls before bt_enable
Prevent the bt_rand function from being called before bt_enable.
Depending on the implementation of bt_rand this function cannot
be called before bluetooth has been initialized. With host supplied
crypto functions the HCI LE rand command is used for example.

The use case for calling bt_id_create before bt_enable is meant for
when the application has storage for the identity instead of the stack.
So we add the requirement that the application has to have storage
for the identity resolving key (IRK) in addition when the local
device is privacy-enabled.

bd7a2fc395 Bluetooth: host: Change directed advertising to privacy-enabled peer
Change the advertising option that controls if the directed advertiser
will use an RPA or the identity address of the peer for the initiator
address.
This option currently has two issues:
 - It behaves differently if the privacy feature has been enabled,
   which can be confusing for application to use.
 - It cannot start a directed advertiser towards a peer that is not
   privacy-enabled and has distributed an IRK.

This commit includes the following changes:
 - When privacy has been enabled in order to advertise towards a
   privacy-enabled peer the BT_LE_ADV_OPT_DIR_ADDR_RPA option must now
   be set (same as when privacy has been disabled).
 - It is now possible to start a directed advertiser using the identity
   address of the peer when privacy-enabled.
 - When privacy has been enabled the advertising option combination
   of using the local identity address and an RPA as the initiator
   address is now disallowed and will return an error code.
   This is done because this combination did not actually work and would
   have used the identity address of the peer instead.
 - If the controller does not support controller-based privacy then
   using the option BT_LE_ADV_OPT_DIR_ADDR_RPA will return ENOTSUP
   because this behavior cannot be done with host-based privacy.

78a6cdb07c Bluetooth: host: Avoid use of array compound literals in API
Attempt to fix C++ error: taking address of temporary array.

According to GCC documentation:
  In C++, a compound literal designates a temporary object that only
  lives until the end of its full-expression.

Finishing with this recommendation:
  As an optimization, G++ sometimes gives array compound literals
  longer lifetimes: when the array either appears outside a function
  or has a const-qualified type.
  But it is probably safest just to avoid the use of array compound
  literals in C++ code.

Fix the issue by introducing INIT macros as an alternative, and use
these in the inline functions to avoid the use of array compound
literals in Bluetooth headers.

was no longer valid when it was used to start the advertiser.
