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[]

When the firmware is reloaded and reset, the packet error count is not.
This can create a condition where the firmware could report an error like
the following if a channel was closed without any new errors:
wctc4xxp 0000:07:08.0: 18446744073709551597 errored receive packets
wcdte.packet_errors is also renamed to wcdte.reported_packet_errors to not
conflict with the packet_errors member of the descriptor lists.

In the case where two transcoders are loaded in a system and one transcoder
experiences an errored receive packet condition, the logic would ping pong the
error between the two cards, causing a runaway stream of errors in the kernel
log.
This fix moves the global error count var into the wcdte struct to allow for
per-card logic.

The IRQF_DISABLED flag was removed in 4.1 in commit
"genirq: Remove the deprecated 'IRQF_DISABLED' request_irq() flag entirely" [1].
By default all interrupt handlers are now run with interrupts disabled and
therefore should all be considered "fast interrupts". Any driver that was still
using the flag will now lock interrupts directly in the handler in case running
on an older kernel that is not disabling interrupts when running the handler.

The cards affected include the TE131/3, TE235/435, A4B, and A8B.
Update all PCIe cards' firmware to increase the incoming and outgoing TDM FIFOs
to 16ms. The FIFOs will only be filled to a depth equal to the driver's latency
setting (ie. 3ms default). The total system latency is not effected. The
firmware and driver now also report the maximum DMA transaction time when in
DEBUG mode to aid in determining if the system is experiencing long PCIe
transactions (ie. TLP completion timeouts).
Decreased the maximum latency to from 20 to 12ms

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.

Kernel version 3.16+, since upstream commit (7f7f25e82d54870d "replace checking
for ->read/->aio_read presence with check in ->f_mode" )[1], does not like it
when dahdi changes the set of allowed file operations on a file descriptor
outside of the context of an open() system call.
DAHDI changes the available file operations when a channel is opened by first
opening /dev/dahdi/channel and then calling the DAHDI_SPECIFY ioctl to bind it
to a particular DAHDI channel. Until DAHDI_SPECIFY is called there weren't any
read()/write() callbacks implemented and therefore after the initial open, the
kernel was setting not setting FMODE_CAN_{WRITE,READ} on the file descriptor
indicating that those operations were not allowed.
Now define empty shell functions on the general dahdi_fops so the vfs layer will
not mark a file descriptor as unwritteable or unreadable on open.
