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.

Introduce filtering for scheduled scans to reduce the number of
unnecessary results (which cause useless wake-ups).

Add a new nested attribute where sets of parameters to be matched can
be passed when starting a scheduled scan.  Only scan results that
match any of the sets will be returned.

At this point, the set consists of a single parameter, an SSID.  This
can be easily extended in the future to support more complex matches.

When the rssi of the current AP drops, both wpa_supplicant and the
firmware may do a background scan to find a better AP and try to
associate. Since firmware based roaming is faster, inform
wpa_supplicant to avoid roaming and let the firmware decide to
roam if necessary.

For fullmac drivers like ath6kl, it is just enough to provide the
ESSID and the firmware will decide on the BSSID. Since it is not
possible to do pre-auth during roaming for fullmac drivers, the
wpa_supplicant needs to completely disconnect with the old AP and
reconnect with the new AP. This consumes lot of time and it is
better to leave the roaming decision to the firmware.
