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.

In case a user has a file descriptor that is used for non-blocking I/O
and the span to which it belongs gets unassigned, its reads and writes
will still yield -EAGAIN.
This commit adds a test for such a case and returns the proper -ENODEV.

gcc-6.3.1 reports the following error when building the driver suite:
drivers/dahdi/voicebus/GpakApi.c: In function 'gpakReadDSPMemoryMap':
drivers/dahdi/voicebus/GpakApi.c:1560:5: warning: this 'if' clause does not guard... [-Wmisleading-indentation]
if (DspStatus != 0)
^~
drivers/dahdi/voicebus/GpakApi.c:1563:2: note: ...this statement, but the latter is misleadingly indented as if it is guarded by the 'if'
for (i = 0; i < MemoryLength_Word16; i++)
^~~
So we'll now update the indentation level (which appears to be a side effect of
mixed tabs and spaces in this file).
NOTE: The GpakAPI files are checkpatch.pl unclean because I did not want to
increase the burden of merging in updates from the original provider, but it may
be time to go ahead and bring the file in compliance with the kernel coding
standards.

The xpp drivers were originally developed seperately and thus had their
own version number. For quite some time they no longer have this version

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.

A script that performs the module loading / unloading instead of the
init script.
Other functionality of the init script is performed by udev hooks. But
manual initiation of modules loading or unloading is still needed on
several occasions.
This script should help enable the removal of the init script from the
DAHDI package.

* 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[]
