* The variable eeprom_release_201 was added in the initialization
script of the FXS module to add a case where it is different from
101 mains.
* However, it tests for "201" and it should apply for any 20x.
* Remove the variable from the init script of module type 6 (new FXS)
as it was not used.

The si32260 chip may enter a state of thermal alarm to avoid
overheating. This disables the channel.
This commit allows automatic restoring of the channel after a certain
timeout (poll_chan_linefeed, by default 30 seconds).
Adds a per-channel counter ("overheats") in
/proc/xpp/XBUS-<n>/XPD-<m>0/fxs_info to count such events.

DAHDI gets notified of changes to battery status and hence to red alarm
on an FXO channel when the status changes. It thus needs to get notified
about it on "startup".
This startup was initially span registration. However following the
separation between device registration and span assignment, the
notification was sent after device registration, whereas it was ignored
if span was not assigned. It happened to work in most cases due to
delays.
This fix moves the startup notifications of battery status to the new
hook that is run on span assignment.

Add an phone device XPD method called 'span_assigned' that gets
called when the XPD's span is assigned.

The upstream 4.11 kernel, in commit (10383aea2f445bce9b2a2b308def08134b438c8e
"kref: Implement 'struct kref' using refcount_t"), changed refcount type on kref
objects. We now need to use refcount_read to read them.

The number of subunits per XPD (which is not trivial in BRI) has been

The packet data length field may have other values in some cases (BRI D
channel). It is also inherently limited to 3 bits.

The xpp drivers were originally developed seperately and thus had their
own version number. For quite some time they no longer have this version
number and report 'Revision: Unknown'.
Get rid of this mechanism.

The test originally did not check any input from the hardware.
Fix it to check the actual (and proper) input from the hardware.

Centos 5 has perl 5.8.8 . It does not support the '//' operator that was
added in perl 5.10. So sadly we have to avoid using it.

The new FXS chip supports two ports for each chip and hence we once
again need to look at hardware differently.
Struct unit_description includes information about all chips/port in a
specific module.

The xpp modules use time differences for various statistics. In one case
xpp_usb creates a histogram of the time it took the system to send USB
packets (URBs). The time difference is used (after adjustments) as an
index to that array.
However if the clock happens to go back at that exact point in time, we
get to write to an arbitrary negative index in this array.

* Drop PCM during sluggish events:
- Drop both rx/tx (was only tx)
- Drop almost all pcm until sluggishness stops (used to drop only
single pcm each time).
- Renamed: "drop_next_pcm" -> "drop_pcm" (to match new semantics)
- Still allow "keep alive" PCM so Astribank will not reset FXS high-voltage.
The "sluggish_pcm_keepalive" parameter set the rate (1/50 by default)
- Added rx/tx drop statistics counters
- Removed "pcm_tx_drops" (replaced by new statistics counters)
* Also improved format of /proc/xpp/XBUS-*/xpp_usb:
- Show cummulative number of sluggish events.
- Clearly show range (in usec) of usb_tx_delay[]
