The device blacklist is not taking care of the address type. Actually
store the address type in the list entries and also use them when
looking up addresses in the table.
This is actually a serious bug. When adding a LE public address to
the blacklist, then it would be blocking a device on BR/EDR. And this
is not the expected behavior.

Magically updating the advertising data when some random command enables
advertising in the controller is not really a good idea. It also caused
a bit of complicated code with the exported hci_udpate_ad function that
is shared from many places.

core. It also makes sure that when powering on with LE enabled or later
on enabling LE the controller has a good default for advertising data.

The bdaddr_to_le() function tries to convert the internal address
type to one that matches the HCI address type for LE. It does not
handle any address types not used by LE and in the end just make
the code a lot harder to read.
So instead of just hiding behind a magic function, just convert
the internal address type where it needs to be converted. And it
turns out that these are only two cases anyway. One when creating
new LE connections and the other when loading the long term keys.
In both cases this makes it more clear on what it going on.

On dual-mode BR/EDR/LE and LE only controllers it is possible
to configure a random address. There are two types or random
addresses, one is static and the other private. Since the
random private addresses require special privacy feature to
be supported, the configuration of these two are kept separate.
This command allows for setting the static random address. It is
only supported on controllers with LE support. The static random
address is suppose to be valid for the lifetime of the controller
or at least until the next power cycle. To ensure such behavior,
setting of the address is limited to when the controller is
powered off.
The special BDADDR_ANY address (00:00:00:00:00:00) can be used to
disable the static address. This is also the default value.
