Andre Guedes f39799f504 Bluetooth: Prepare start_discovery
This patch does some code refactoring in start_discovery function
in order to prepare it for interleaved discovery support.

MGMT_ADDR_* macros were moved to hci_core.h since they are now used
to define discovery type macros.

Discovery type macros were defined according to mgmt-api.txt
specification:

Possible values for the Type parameter are a bit-wise or of the
following bits:

	1	BR/EDR
	2	LE Public
	3	LE Random

By combining these e.g. the following values are possible:

	1	BR/EDR
	6	LE (public & random)
	7	BR/EDR/LE (interleaved discovery)

This patch makes sure that devices with stronger signal (RSSI closer to
0) are sorted first in the resolve list and will therefore get their
names resolved first during device discovery. Since it's more likely
that the device the user is trying to discover has a strong signal due
to its proximity this ensures that the user gets the "device found"
event for it more quickly.

Brian Gix 47c15e2b33 Bluetooth: Differentiate LE User Pairing Responses
Low Energy (LE) pairing responses must be recognized and handled
differently from BR/EDR pairing responses. BR/EDR responses are
handled via HCI commands by the LMP layer, and LE responses are
handled by the Host.

Johan Hedberg ca69b7957b Bluetooth: Create a unique mgmt error code hierarchy
The management protocol uses a single byte for error codes (aka command
status). In some places this value is directly copied from HCI and in
other a POSIX error number is used. This makes it impossible for
user-space to uniquily decipher the meaning of an error.

To solve this issue a new mgmt-specific set of error codes is added
along with a conversion table for HCI status values.

The current global pending command list in mgmt.c is racy. Possibly the
simplest way to fix it is to have per-hci dev lists instead of a global
one (all commands that need a pending struct are hci_dev specific).
This way the list can be protected using the already existing per-hci
dev lock. To enable this refactoring the first thing that needs to be
done is to ensure that the mgmt functions have access to the hci_dev
struct (instead of just the dev id).

According to the Bluetooth spec, the inquiry cancel command should

As HCI_INQUIRY flag is only set just after an inquiry command status
event occurs and it is cleared just after an inquiry complete event
occurs, the inquiry cancel command should be issued only if HCI_INQUIRY
flag is set.

Antti Julku 5e762444b0 Bluetooth: Add mgmt events for blacklisting
Add management interface events for blocking/unblocking a device.
Sender of the block device command gets cmd complete and other
mgmt sockets get the event. Event is also sent to mgmt sockets when
blocking is done with ioctl, e.g when blocking a device with
hciconfig. This makes it possible for bluetoothd to track status
of blocked devices when a third party block or unblocks a device.

Event sending is handled in mgmt_device_blocked function which gets
called from hci_blacklist_add in hci_core.c. A pending command is
added in mgmt_block_device, so that it can found when sending the
event - the event is not sent to the socket from which the pending
command came. Locks were moved out from hci_core.c to hci_sock.c
and mgmt.c, because locking is needed also for mgmt_pending_add in
mgmt.c.
