MGMT_EV_DEVICE_DISCONNECTED will now expose the disconnection reason to
userland, distinguishing four possible values:
0x00 Reason not known or unspecified
0x01 Connection timeout
0x02 Connection terminated by local host
0x03 Connection terminated by remote host
Note that the local/remote distinction just determines which side
terminated the low-level connection, regardless of the disconnection of
the higher-level profiles.
This can sometimes be misleading and thus must be used with care. For
example, some hardware combinations would report a locally initiated
disconnection even if the user turned Bluetooth off in the remote side.

Now that most flags are persistent, only the LE_SCAN flag should be
cleared after a reset.

Since neither High Speed (HS) nor Low Energy (LE) are fully implemented
yet, only expose them in supported settings when enabled.

The HCI notifier handling was never used outside of Bluetooth core layer
and thus remove it and replace it with direct function calls. Also move
the stack internal event generation into the HCI socket layer.

The sending functions for HCI raw and control sockets have nothing in
common except that they iterate over the socket list. Split them into
two so they can do their job more efficient. In addition the code becomes
more readable.

This patch adds interleaved discovery support to MGMT Start
Discovery command.
In case interleaved discovery is not supported (not a dual mode
device), we perform BR/EDR or LE-only discovery according to the
device capabilities.

This patch merges DISCOVERY_INQUIRY and DISCOVERY_LE_SCAN states
into a new state called DISCOVERY_FINDING.
From the discovery perspective, we are pretty much worried about
to know just if we are finding devices than what exactly phase of
"finding devices" (inquiry or LE scan) we are currently running.
Besides, to know if the controller is performing inquiry or LE scan
we should check HCI_INQUIRY or HCI_LE_SCAN bits in hdev flags.
Moreover, merging this two states will simplify the discovery state
machine and will keep interleaved discovery implementation simpler.

The Set Link Security mgmt command is used to enable or disable link
level security, also known as Security Mode 3. This is rarely enabled in
modern systems but the command needs to be available for completeness,
qualification purposes and those few systems that actually want to
enable it.

This patch adds to hci_core the hci_do_le_scan function which
should be used to scan LE devices.
In order to enable LE scan, hci_do_le_scan() sends commands (Set
LE Scan Parameters and Set LE Scan Enable) to the controller and
waits for its results. If commands were executed successfully a
delayed work is scheduled to disable the ongoing scanning after
some amount of time. This function blocks.
