rt2x00: Only configure hardware when radio is enabled
Some hardware configuration registers such as antenna and channel configuration
can only be written when the radio is enabled. Previously, we didn't consider
this, so some configuration items could be set inconsistently after reenabling
the radio. This patch changes the config() handler to only reprogram the
hardware when the radio is enabled. Configuration changes that are made while
the radio is off are postponed until the radio is switched back on. We also
leave the radio turned off during initialization and only enable it when
requested by mac80211. This allows us to get rid of the DIRTY_CONFIG flag,
because the device is now guaranteed to be completely initialized when brought
up by mac80211.

rt2x00: Fix race conditions in flag handling
Some of the flags should be accessed atomically to
prevent race conditions. The flags that are most important
are those that can change often and indicate the actual

The big flag rename was done to move all state flags to
the same naming type as the other rt2x00dev flags and
made sure all places where the flags were used were changed. ;)
Thanks to Stephen for most of the queue flags updates,
which fixes some of the most obvious consequences of the
race conditions. Among those the notorious:

dccp: Toggle debug output without module unloading
This sets the sysfs permissions so that root can toggle the `debug'
parameter available for nearly every DCCP module. This is useful
since there are various module inter-dependencies. The debug flag
can now be toggled at runtime using
echo 1 > /sys/module/dccp/parameters/dccp_debug

dccp: Empty the write queue when disconnecting
dccp_disconnect() can be called due to several reasons:
1. when the connection setup failed (inet_stream_connect());
2. when shutting down (inet_shutdown(), inet_csk_listen_stop());
3. when aborting the connection (dccp_close() with 0 linger time).
In case (1) the write queue is empty. This patch empties the write queue,
if in case (2) or (3) it was not yet empty.
This avoids triggering the write-queue BUG_TRAP in sk_stream_kill_queues()
later on.

packets that were originally intended for the soon-disconnected end (compare
with call to tcp_write_queue_purge in tcp_disconnect()).

"[..] options with nonsensical lengths (length byte less than two or more

ignored, and any option space following an option with nonsensical length
MUST likewise be ignored."
Hence in the following cases erratic options will be ignored:
1. The type byte of a multi-byte option is the last byte of the header
options (i.e. effective option length of 1).
2. The value of the length byte is less than the minimum 2. This has been
changed from previously 3: although no multi-byte option with a length
less than 3 yet exists (cf. table 3 in 5.8), a length of 2 is valid.
(The switch-statement in dccp_parse has further per-option length checks.)

dccp: Always generate a Reset in response to option errors
RFC4340 states that if a packet is received with an option error (such as a
Mandatory Option as the last byte of the option list), the endpoint should
repond with a Reset.
In the LISTEN and RESPOND states, the endpoint correctly reponds with Reset,
while in the REQUEST/OPEN states, packets with option errors are just ignored.
The packet sequence is as follows:
Case 1:
Endpoint A Endpoint B
(CLOSED) (CLOSED)
<---------------- REQUEST
RESPONSE -----------------> (*1)
(with invalid option)
<---------------- RESET
(with Reset Code 5, "Option Error")
(*1) currently just ignored, no Reset is sent
