The internals of the HCI request framework should not be leaking to

All the HCI sockets and ioctl based definitions have been in a global
header file that also includes all the HCI protocol structures. To
make this a bit cleaner, move them into its own file.
This also adjusts fs/compat_ioctl.c to only include this new file
and not all the protocol structures that are not needed.

When the controller is brought up using legacy ioctl, the setting of
the HCI_PAIRABLE flag should happen then. Previously it was set during
enumeration and when retrieving device information.
This change also will not set the HCI_PAIRABLE flag when the controller
is used with the HCI User Channel operation.

During the initial setup phase, the controller is powered on and will
be powered off again if it is not used within the auto-off timeout.
Userspace using ioctl does not know about the difference between the
initial setup phase and a controller being present. It is a bad idea
to keep the controller powered by just looking at the device list or
device information. Instead just tell userspace that the controller
is still down.

The Set Connectable/Discoverable mgmt handlers use a hci_request with a

Since the HCISETSCAN ioctl is the only non-mgmt user we care about for
setting the right discoverable state we can simply do the necessary
updates in the ioctl handler function instead. This then allows the
removal of the mgmt_discoverable function and should simplify that state
handling considerably.

The mgmt_connectable function has been used to ensure that the right
actions to HCI_CONNECTABLE are taken when the HCI_Write_Scan_Enable
command is triggered by something else than mgmt. The only other user
that we really care about is the HCISETSCAN ioctl code, so we can
actually more simply perform the needed changes there instead.

When the SMP context is created all flags default to zero. To determine
that we are the initiators it's therefore best to simply change the flag
value when we know we're sending the first SMP PDU. Clearing the flag
when receiving a Pairing Request is not correct since the request may be
a response to a previous Security Request from us (for which we would
already have correctly set the flag). Same goes for receiving a Security
Request which may be coming after us already starting pairing by sending
a Pairing Request.

For incoming requests we want to let the user know that pairing is
