We can't do synchronous HCI command sending in any settings commit()
callback, since we don't know what context the callback is being called
from. One particular deadlock can happen if settings_load() is called from
the preemptible main thread:
main()
|--> settings_load() (aquire settings_lock mutex)
|-->commit callback A that defers to system wq
|-->commit callback B that calls bt_hci_cmd_send_sync()
system wq from the previous deferral from within settings_load():
|--> work item
|--> settings_save_one()
|--> attempt to aquire settings_lock mutex
In the above scenario, the bt_hci_cmd_send_sync() call from the main thread
depends on the system workqueue being processed (since that's what does HCI
command processing by default), while at the same time holding the settings
subsystem's mutex. At the same time, a system wq item tries to store
something into settings, however it deadlocks waiting for the settings
mutex.
The actual scenario that we have in the Bluetooth subsystem is where
"commit callback A" is commit_settings() in host/settings.c, and "commit
callback B" is keys_commit() in host/keys.c.
The solution to the deadlock is to take advantage of deferred bt_id_add()
handling which already exists, i.e. set a flag and deferre the actual
adding to the system workqueue.

If the HCI status of a complete event is not BT_HCI_ERR_SUCCESS,
the remaining parameters could be invalid.
In this case, the params is passed as NULL pointer to the callbacks.
- LE CS Read Remote Supported Capabilities Complete event
- LE CS Read Remote FAE Table Complete event
- LE CS Config Complete event
- LE CS Security Enable Complete event
- LE CS Procedure Enable Complete event
This change avoids forwarding the invalid fileds to the applications.

Added a new function, bt_conn_is_type, that returns whether
the provided conn object is of the provided type.
This check is then used to ensure that the conn objects
supplied to other bt_conn function are of the right type.
The right type has also been documented for these functions.
This is an initial commit for a larger change in the BT Host,
as similar checks should be added to the L2CAP, GATT, ISO,
Audio and possibly Mesh APIs.
The type check could have been implemented by using the
bt_conn_get_info function, but that requires additional
function calls as well as memory allocation and copy.
Since bt_conn_is_type is designed to be widely used, it
was suited for its own function.

Default the Minimum encryption key size to 16.
Key with reduced size is easier to brut force.
Disable LE legacy pairing by default since it's not secure.
These defaults should suite majority of newly developed applications.

so applications that really need less secure option consciously change it,
not the other way around.

This change makes sure that when a call to `bt_id_set_scan_own_addr` is
sucessful, i.e., the return value is 0, the `own_addr_type` will
be set by the `bt_id_set_scan_own_addr`.
Not setting the `own_addr_type` in a successful call to
`bt_id_set_scan_own_addr` causes, for example,
the `start_le_scan_ext` method in `scan.c` to use an
uninitialized `own_addr_type`.
Eventually this results in an unexpected failure further down in
`start_le_scan_ext`, when sending HCI command to controller with
an uninitialized `own_addr_type`.

The host-based adv auto-resume function has both a problematic
implementation and disagreement in the community around how it should
behave. See the issue linked resolved below for details.
This patch makes the deprecation visible to the user. The user will be
better served by a auto-resume tailored their applications use case,
based on more primitive host API like `conn_cb.recycled`, which has
obvious behavior that is unlikely to change.

Very very weird behavior.
Deleting the `options & BT_LE_ADV_OPT_USE_NRPA` branch in
`id.c:bt_id_set_adv_own_addr` makes the test pass. But add a log in that
branch, and you'll see that we never take it in the UT binary..
I don't have time for this, maybe some compiler guru or C language
lawyer can look at that decompiled function and figure out the root
cause.
Someone should also really fix the Bluetooth unit tests and make them
run on any Bluetooth related PR. Also nightly.

To make the scanner module more understandable and more streamlined, I
reworked the update mechanism of the scanner. The scanner tracks now the
parameters that were used to enable it and the reason why it is running.
This facilitates state logic and allows other modules to "start the
scanner", altough it is already running.
This is mostly a refactoring and not a functional change.
Added a test to verify the behavior.

The project() will also set the C compiler, if not set already.
If project() is called first, then conflict arises on the C compiler
selection and thus the following message is seen:
> You have changed variables that require your cache to be deleted.
> Configure will be re-run and you may have to reset some variables.
> The following variables have changed:

To make it easier to understand the code, the following was done:
- Use INITIATING/ADV for state names that are exclusive to central
or peripheral. Previously it was not necessarily clear that the state
BT_CONN_CONNECTING was for central only by just looking at where
it was used. The terms INITIATING/ADV were used in favor
of central and peripheral as these terms also work for SCO connection
establishment.
- BT_CONN_CONNECTING_SCAN -> BT_CONN_SCAN_BEFORE_INITIATING
to make it more clear that we are not scanning and connecting at
the same time. The new name should make it more clear why we are
scanning - only with the intention to start the initiator later.
- BT_CONN_CONNECTING_AUTO -> BT_CONN_INITIATING_FILTER_LIST.
This makes it clear that this state is something different than
BT_CONN_AUTO_CONNECT.

Added a Kconfig option that makes the RPA sharing feature optional. By
default, the Zephyr Bluetooth stack now uses the RPA rotation policy
that was active before the introduction of the RPA sharing functionality
in the following PR:
https://github.com/zephyrproject-rtos/zephyr/pull/55449
The new Kconfig option configures the advertising sets linked with the
same Bluetooth identity to use the same Resolvable Private Address in
a given rotation period. After the RPA timeout, the new RPA is
generated and shared between the advertising sets in the subsequent
rotation period.
When this option is disabled, the generated RPAs of the advertising
sets differ from each other in a given rotation period.
