e70c556dcc Bluetooth: Add full storage support for multiple identities
Update the storage handling to take into account multiple identities.
We can save a bit of code by using the new bt_id_create() API from
within settings.c.

Also make the treatment of addr & irk parameters to bt_id_create()
consistent, in that NULL is acceptable for both of them.

3ed01b48b9 Bluetooth: Remove redundant BT_DEV_ID_STATIC_RANDOM flag
This flag was both redundant and creates confusion with potentially
multiple identity addresses (it was only referring to the first
identity address). We can simply just look at the type of the identity
address wanting to be used.

5708f1e8b1 Bluetooth: Add infrastructure to handle multiple identities
Make it possible to have multiple identity addresses as an LE
peripheral. For central role only the default identity is supported
for now. This also extends the flash storage in a backward compatible
way.

1329763a14 Bluetooth: Fix storing name in plain text
Settings consider the character space the end of the value, so instead
encode the name using settings_str_from_bytes and restore it with
settings_bytes_from_str.

2637c978fe Bluetooth: Store device name
This uses bt_dev to store the name and allow changing it at runtime, in
addtion to that if CONFIG_BT_SETTINGS is defined make the name
persistent.

Fixes #8357

ae829b269d Bluetooth: Fix unchecked settings value lengths
We should check for valid lengths, not just because flash may have
become corrupted, but also because this fixes coverity errors, such as
CID 186030.

Fixes #7739

f36ea83628 Bluetooth: Add support for persistent pairing keys storage
Integrate the bt_keys submodule with bt_settings. Add a new
bt_keys_store() API to write keys to flash, and extend the existing
bt_keys_clear() to remove the keys from flash.

Along with this, add some helpers for genrating settings key values
containing a bluetooth address, as well as for decoding them to get
the binary bt_addr_le_t.

and iterate the list from the various settings callbacks.

d22b7c9f2d Bluetooth: Remove bt_storage API
The same functionality is now supported by the settings-based
solution, so remove bt_storage out of the way. There were stubs in
bt_storage to handle per-peer information (e.g. pairing keys) but this
was never actually implemented in full. The next step is to add this
support to the settings-based solution.

Leave the code for generating temporary IRK and identity address in
case BT_SETTINGS is not enabled. Also leave the code for using vendor
HCI to read the identity address, in which case the settings
implementation will not touch it.

Introduce a new bt_unpair() API to replace the removed
bt_storage_clear(), since the latter was actually doing more than just
storage management: it was also handling runtime storage of pairing
information. Later, the bt_unpair() implementation will be extended to
clear settings-based pairing storage.

There is one feature that the bt shell module looses: the ability to
give a specific identity address to the "init" command as a parameter.
We might look later in the future if this is really needed, and add a
separate API for this.

b997a283f7 Bluetooth: Introduce skeleton for settings-based storage
Introduce a basic skeleton for peristent storage based on the settings
subsystem. Also enable support for this to the peripheral sample
application, so the new code gets exersized by CI. For now, the
implementation provides the same level support as the bt_storage API
ever did, i.e. for the identity address and the IRK.
