For each kernel release where commands or events are added to the
management interface, the revision field should be increment by one.

The increment should only happen once per kernel release and not
for every command/event that gets added. The revision value is for
informational purposes only, but this simple policy would make any
future debugging a lot simple.

When powering on we need to apply whatever name has been set through
mgmt_set_local_name. The appropriate place for this is mgmt_powered()
and not hci_setup() since this needs to be applied also if the HCI init
sequence was already completed but the adapter was still "powered off"
from a mgmt perspective due the the HCI_AUTO_OFF still being set.

This flag is of no use right now and is in fact harmful in that it
prevents the HCI_MGMT flag to be set for any controllers that may need
it after the first one that bluetoothd takes into use (the flag is
cleared for the first controller so any subsequent ones through the same
bluetoothd mgmt socket never get the HCI_MGMT flag set).

By moving the command handlers into a table (the index being equal to
the opcode) the lookup is made a bit more efficient. Having a struct to
describe each handler also paves the way to add more meta-data for each
handler, e.g. the minimum message size for the command and allow
handling of common tasks like this in a centralized place.

The read_controller_info is typically the first command that user space
sends when taking a controller into use. This is also the reason why
this command has been used as the trigger to set the HCI_MGMT flag.
However, when not running the user-space daemon and using command line
tools it is possible that read_controller_info is not the first
controller specific command. This patch moves the HCI_MGMT
initialization to a generic place where it will be set for whatever
happens to be the first mgmt command targetting a specific controller.
