'schluffen()' essentially duplicates the functionality of the standard
Linux 'interruptible_sleep_on()' function.
There may still be some race conditions that can be closed here, but
most of the command queue processing is sloted for conversion to
something more like in the single span driver in order to reduce the
time in interrupt context spent scanning for commands to the modules.

wake_up_interruptible() will change the state of waiting tasks back to
TASK_RUNNING, therefore, we want to ensure we set TASK_INTERRUPTIBLE
before checking the conditions that we're going to sleep on.
In practice, this closes a small window were the caller may be put to
sleep when the condition is true, and have to wait for another event to
come in order to wake from the sleep.

'interruptible_sleep_on()' is the Linux equivalent of 'tsleep()'. When
we're sleeping for a condition, we can also just use
wait_event_interruptible to close a potential race where the condition
goes true between the time we checked it and when we go to sleep waiting
on the event.

It can be necessary to have low frequency filter for tx signal of DAHDI.
Otherwise, low-frequency signal from IP can reach a leased line, and
return back with nonlinear distortions. This will break an echo

If the DSP ever finds it's way into a bad state it can be possible for a
timeslot to get 'wedged'. All attempts to create a channel in a wedged
timeslot will fail and the WARN_ON macro can quickly fill the logs.
This change adds some more debugging information (which timeslot is wedged)
along with the result code from the DSP and puts it all behind a
printk_ratelimit.

Fixes a regression singce r8873: if pri_protocol is not explicitly set
(in /etc/dahdi/xpp.conf) and the device has (licences for) less than 4
"PRI" (E1/T1) ports, the initialization script will attempt to read from
a non-existing SysFS file, and bail out, resulting in a the device
failing to initialize.
For those non-existing ports we can just skip that part of the
initialization. So we just skip it.
Work around: explicitly set pri_protocol to E1 or T1, as needed.

The bigzaplock was used to prevent changes to all the channels during
masterspan processing while conference parameters were changing. The
master span processing also took a global lock out on the chan_lock to
prevent new channels from being registered or unregistered during
processing. Instead of grabbing both those locks, just changing the
semantics of chan_lock to those of bigzaplock seems to fit the bill and
removes another lock from the driver (and saves ~10 ns on a 2.40 GHz
Xeon in prcocess_masterspan)
chan_lock is a candidate for conversion to RCU but usage in conferencing
(bigzaplock type usage) needs to be audited carefully before conversion.
