Every command handler of mgmt does a cast to the command structure
so it can properly interpreted. So we can avoid that cast if we

This patch updates mgmt_ev_device_connected and mgmt_ev_device found to
include an EIR-encoded remote name and class whenever possible. With
this addition the mgmt_ev_remote_name event becomes unnecessary and can
be removed. Since the connected event doesn't map to hci_conn_complete
anymore a HCI_CONN_MGMT_CONNECTED flag is added to track when mgmt has
been notified about a connection.

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.
