ffdfdfb66b xpp_usb: Fix potential corruption on clock rewind
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.

404a67d089 xpp: improve handling of USB sluggishness
* 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[]

1559db9d1a dahdi: strnicmp() -> strncasecmp()
With commit (af3cd13501 "lib/string.c: remove strnicmp()") [1] dahdi can no
longer call strnicmp directly. strncasecmp was added into lib/string.c in kernel
version 2.6.22 so we'll map calls to strncasecmp to strnicmp for any kernel
before that.

This is necessary to compile against kernels >= 4.0.

b3a6b91858 Do not call dahdi_span_ops.open with spinlock held.
This makes the open symmetrical with the close. It is also considered good
practice to not call through callbacks with spinlocks held.

I modified all the drivers where I could not tell whether it was necessary to
hold the chan->lock with interrupts disabled to simply take the lock inside the
callback.

779d62791c Add #include <linux/slab.h> to all files that call kzalloc|kmalloc|kfree.
Some architectures, like arm, do not automatically pull in the definitions for
kzalloc and friends. This allows DAHDI to build on those platforms.

15ff405dc8 xpp: pri: Fix more than a single CAS/R2 call
Fixes regression from bb63d03bba (before
v2.7.0). This failed to set the PCM mask on a CAS span when
DAHDI_AUDIO_NOTIFY was not set.

As the first channel of each xbus would be enabled (for
synchronization), a single call may still have passed.

This patch sets the PCM mask on any CAS channel explicitly.

XPP devices have implicit support for device registration and

606dd58a47 xpp: fix failed multi-PRI E1<->T1 transition
In an Astribank with >= 2 PRI ports, switching from E1 to T1 at run-time
may fail at the DAHDI_CHANCONFIG ioctl on the first channel in a span,
That is, on first run of dahdi_cfg, it fails on second span, on second:
it fails on third span, etc.

The code clears the D-channel information on the DAHDI_CHANCONFIG call
for the first channel in the span.

However The code tested for the global "channo" rather than the per-span
"chanpos" to check for the first channel in the span. This the test
failed.

  - Always call dahdi_init_span()

* Improve phonedev_cleanup() safety:
  - NULL pointers after free.
  - Zero number of channels at the end.

* Refactor channel allocation out of phonedev_init():
  - Into phonedev_alloc_channels()
  - Also called from xpd_init_span() to prevent duplicated logic.
