mac80211: fix dynamic-ps/pm_qos magic numbers
mac80211 uses pm_qos (/dev/network_latency) in order to determine the
dynamic ps timeout (or disable the dynamic-ps at all in some cases).
commit
ff616381 added a comparison for the current network_latency
against one high value (1900ms), and against the default value
(2000sec, rather than the commented 2sec).
however, the representation of 1900ms was incorrect:
1900ms = 1900000us ( !=
1900000000 )
fix it by using USEC_TO_MSEC/SEC consts.

cfg80211/mac80211: add mesh join/leave commands
Instead of tying mesh activity to interface up,
add join and leave commands for mesh. Since we
must be backward compatible, let cfg80211 handle
joining a mesh if a mesh ID was pre-configured
when the device goes up.
Note that this therefore must modify mac80211 as
well since mac80211 needs to lose the logic to
start the mesh on interface up.
We now allow querying mesh parameters before the
mesh is connected, which simply returns defaults.
Setting them (internally renamed to "update") is
only allowed while connected. Specify them with
the new mesh join command instead where needed.
In mac80211, beaconing must now also follow the
mesh enabled/not enabled state, which is done
by testing the mesh ID.

Bluetooth: Automate remote name requests
In Bluetooth there are no automatic updates of remote device names when
they get changed on the remote side. Instead, it is a good idea to do a
manual name request when a new connection gets created (for whatever
reason) since at this point it is very cheap (no costly baseband
connection creation needed just for the sake of the name request).
So far userspace has been responsible for this extra name request but
tighter control is needed in order not to flood Bluetooth controllers
with two many commands during connection creation. It has been shown
that some controllers simply fail to function correctly if they get too
many (almost) simultaneous commands during connection creation. The
simplest way to acheive better control of these commands is to move
their sending completely to the kernel side.
This patch inserts name requests into the sequence of events that the
kernel performs during connection creation. It does this after the
remote features have been successfully requested and before any pending
authentication requests are performed. The code will work sub-optimally
with userspace versions that still do the name requesting themselves (it
shouldn't break anything though) so it is recommended to combine this
with a userspace software version that doesn't have automated name
requests.
