The source addressed was based on the public address of the HCI device,
but with LE connections this not always the case. For example single
mode LE-only controllers would use a static random address. And this
address is configured by userspace.
To not complicate the lookup of what kind of address is in use, store
the correct source address for each HCI connection.

When establishing LE connections, it is possible to use a public

is only known when creating connections, so make sure it is

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.

Really early versions of the Bluetooth specification were unclear
with the behavior of HCI Reset for USB devices. They assumed that
also an USB reset needs to be issued. Later Bluetooth specifications
cleared this out and it is safe to call HCI Reset without affecting
the transport.
For old devices that misbehave, the HCI_QUIRK_RESET_ON_CLOSE quirk
was introduced to postpone the HCI Reset until the device was no
longer in use.
One of these devices is the Digianswer BPA-105 Bluetooth Protocol
Analyzer. The only problem now is that with the quirk set, the
HCI Reset is also executed at the end of the setup phase. So the
controller gets configured and then it disconnects from the USB
bus, connects again, gets configured and of course disconnects
again. This game goes on forever.
For devices that need HCI_QUIRK_RESET_ON_CLOSE it is important
that the HCI Reset is not executed after the setup phase. In
specific when HCI_AUTO_OFF is set, do not call HCI Reset when
closing the device.

The scan interval and window parameters are used for LE passive
background scanning and connection establishment. This allows
userspace to change the values.
These two values should be kept in sync with whatever is used for
the scan parameters service on remote devices. And it puts the
controlling daemon (for example bluetoothd) in charge of setting
the values.
Main use case would be to switch between two sets of values. One
for foreground applications and one for background applications.
At this moment, the values are only used for manual connection
establishment, but soon that should be extended to background
scanning and automatic connection establishment.

The scan interval and window for LE passive scanning and connection
establishment should be configurable on a per controller basis. So
introduce a setting that later on will allow modifying it.
This setting does not affect LE active scanning during device
discovery phase. As long as that phase uses interleaved discovery,
it will continuously scan.

If we have a wiphy with an ISO3166-alpha2 regulatory domain
programmed with the strict flag set we wait until the wiphy
gets its wiphy->regd programmed before allowing regulatory
domains hints other than country IE hints from processing
on the wiphy. The existing check however discards the
possibility of custom regulatory domains having also used
the strict flag and these will not have the wiphy->regd
set. Custom strict regulatory domains never set the wiphy->regd
though as such currently all regulatory hints other than
country IE hints are being ignored on these wiphys.
All custom strict regulatory domains set the wiphy with the
WIPHY_FLAG_CUSTOM_REGULATORY and use wiphy_apply_custom_regulatory().
Enhance the check for the strict ISO3166-alpha2 regulatory domain
case by exempting the WIPHY_FLAG_CUSTOM_REGULATORY case. This
will enable other regulatory hints to be processed now for
these strict custom regulatory domains.
