I apparently forgot all about HPEC when updating the echocans for the change
in the factory and echocan ops structures related to echocan naming. The HPEC
wrapper should now be up to date with the rest of DAHDI.

Changed the echocan factory name to a function (get_name) called to get the
name. This allows a factory to return a different name when being called in
reference to a channel such as in the case of hardware echo cancellers. To
further accommodate this change for HWEC, a new echocan_name function was
added to the span ops struct and is used in hwec_factory in dahdi-base for
all cards that support hardware echo cancellation.

Remove the code that allowed hardware echo cancellation to automatically
override software cancellation and prevented SWEC from working at all on a
card if HWEC was installed. All EC now uses the standard modular EC interface.
Additionally, the "SWEC" identifier on channel lines in /proc/dahdi has been
changed to "ECTYPE" to avoid confusion.

The wcte12xp does all the checking for alarm in a user space workqueue.
Most of this time is spent sleeping waiting for reads from the framer to
complete. Tasks in uninterruptible sleeps are added to running tasks
for the purposes of calculating load average. This change makes the
sleeps interruptible so as to not affect the load average as much.
For example, the following command will load and configure the driver and
then print the load average every 10 seconds.
]# modprobe wcte12xp && dahdi_cfg && ((x=12)); while [[ $x -gt 0 ]]; do cat
/proc/loadavg; sleep 10; let x=$x-1; done

'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
