SDP and SIP headers are quite different, SIP can have continuation lines,
leading and trailing whitespace after the colon and is mostly case-insensitive
while SDP headers always begin on a new line and are followed by an equal
sign and the value, without any whitespace.

Introduce new SDP header parsing function and convert all users that used
the SIP header parsing function. This will allow to properly deal with the
special SIP cases in the SIP header parsing function later.

Introduce expectation classes and policies. An expectation class
is used to distinguish different types of expectations by the
same helper (for example audio/video/t.120). The expectation
policy is used to hold the maximum number of expectations and
the initial timeout for each class.

The individual classes are isolated from each other, which means
that for example an audio expectation will only evict other audio
expectations.

This is useful for the SIP helper and signalling expectations.
We don't want to create a full-blown expectation with a wildcard
as source based on a single UDP packet, but need to know the
final port anyways. With inactive expectations we can register
the expectation and reserve the tuple, but wait for confirmation
from the registrar before activating it.

rt73usb and rt2500usb used in_atomic to determine
if a configuration step should be rescheduled or not.
Since in_atomic() is not a valid method to determine
if sleeping is allowed we should fix the way this is handled
by adding a new flag to rt2x00.

In addition mark LED class support for the drivers broken
since that also uses the broken in_atomic() method but
so far no solution exists to have LED triggers work only
in scheduled context.

It has been observed on rt2500pci hardware that some
frames received with signal 0x0C do not have the OFDM
flag set.

Signals can have 2 meanings:
 1) The PLCP value
 2) The bitrate * 10

For rt2500pci (1) is for frames received with a OFDM rate,
and (2) is for frames received with a CCK rate.
But 0x0C is a invalid bitrate value but is a valid PLCP
value for 54Mbs (obvious OFDM rate).
This means that it is possible that the hardware does not
set the OFDM bit correctly under all circumstances.
This results in rt2x00 failing to detect the rate and
mac80211 triggering a WARN_ON() and dropping the frame.

To bypass this, print a warning when such a frame is received,
and reset the rate to the lowest supported rate for the current band.

When you have an AP on channel 13, it will currently often enough
be listed in scan results even when the regulatory domain restricts
to channels 1-11. This is due to channel overlap. To avoid getting
very strange failures, don't show such APs in the scan results. The
failure mode will now go from "I can see the AP but not associate"
to "I can't see the AP although I know it's there" which is easier
to debug.

This problem was first really noticed by Jes Sorensen.
