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.

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.
