Bluetooth: Fix rejected connection not disconnecting ACL link
When using DEFER_SETUP on a RFCOMM socket, a SABM frame triggers
authorization which when rejected send a DM response. This is fine
according to the RFCOMM spec:
the responding implementation may replace the "proper" response
on the Multiplexer Control channel with a DM frame, sent on the
referenced DLCI to indicate that the DLCI is not open, and that
the responder would not grant a request to open it later either.
But some stacks doesn't seems to cope with this leaving DLCI 0 open after
receiving DM frame.
To fix it properly a timer was introduced to rfcomm_session which is used
to set a timeout when the last active DLC of a session is unlinked, this
will give the remote stack some time to reply with a proper DISC frame on
DLCI 0 avoiding both sides sending DISC to each other on stacks that
follow the specification and taking care of those who don't by taking
down DLCI 0.

Bluetooth: Add support for Retransmission and Monitor Timers
L2CAP uses retransmission and monitor timers to inquiry the other side
about unacked I-frames. After sending each I-frame we (re)start the
retransmission timer. If it expires, we start a monitor timer that send a
S-frame with P bit set and wait for S-frame with F bit set. If monitor
timer expires, try again, at a maximum of L2CAP_DEFAULT_MAX_TX.

The current mwl8k_priv->fw_lock spinlock doesn't actually protect
against multiple commands being submitted at once, as it is not kept
held over the entire firmware command submission. And since waiting
for command completion sleeps, we can't use a spinlock anyway.
To fix mwl8k firmware command serialisation properly, we have the
following requirements:
- Some commands require that the packet transmit path is idle when
the command is issued. (For simplicity, we'll just quiesce the
transmit path for every command.)
- There are certain sequences of commands that need to be issued to
the hardware sequentially, with no other intervening commands.
This leads to an implementation of a "firmware lock" as a mutex that
can be taken recursively, and which is taken by both the low-level
command submission function (mwl8k_post_cmd) as well as any users of
that function that require issuing of an atomic sequence of commands,
and quiesces the transmit path whenever it's taken.

wl1251: halt the embedded CPU before loading firmware
After initial power-up, the embedded cpu is usually halted. However,
if we down the interface and only do a soft reset before bringing
the interface back up, it will still be running and the firmware
loading code will bail out. This change halts the CPU before loading
the firmware, enabling a second call to wl1251_boot() to succeed
without a hard reset.

mac80211: Decouple fail_avg stats used by mesh from rate control algorithm.
Mesh uses the tx failure average to compute the (m)path metric. This used to
be done inside the rate control module. This patch breaks the dependency
between the mesh stack and the rate control algorithm. Mesh will now work
independently of the chosen rate control algorithm.
The mesh stack keeps a moving average of the average transmission losses for
each mesh peer station. If the fail average exceeds a certain threshold, the
peer link is marked as broken.

rt2800pci can handle different retry rates,
it will always step 1 rate down after a failed
transmission so creating the retry rate list
for mac80211 is quite simple.
