The intent here is to flag to users that the maintenance counters are
not collected for spans exported by the wcte12xp driver.
dahdi_maint before this change:
# dahdi_maint -s 1
Span 1:
>Framing Errors : 0:
>CRC Errors : 0:
>Code Violations : 0:
>E-bit Count : 0:
>General Errored Seconds : 0:
And after:
# dahdi_maint -s 1
Span 1:
>Framing Errors : -1:
>CRC Errors : -1:
>Code Violations : -1:
>E-bit Count : -1:
>General Errored Seconds : -1:
This can be combined with a change to dahdi_maint to recognize that the
errors are -1 and print an even more explicit warning.

There were a couple of reports that MeetMe conferences were not
working in 2.5.0.1 and that downgrading to 2.4.1.2 resolved the
issue. This could occur if there were no analog spans in a system,
and all the digital spans were out of alarm before DAHDI_STARTUP
ioctl was called by dahdi_cfg. If the spans were *not* out of alarm,
they would be marked master when the span changes it's alarm state.
This would result in a condition where no spans were marked as the
"master" and so the core timer was handling conferencing. The core
timer runs by default at 4ms and most board drivers run at 1ms
intervals, but a channel currently only buffers up 2ms of data when
conferenced. Therefore, 2ms of audio from a board was continuously
dropped from the conference every 4ms by default.
This fixes a regression first introduced in 2.5.0 which was
specifically added in revision r9611 "dahdi: Do not locate new
master in interrupt context."

* Bug sympthoms: wrong FSK VMWI sent few seconds after
offhook. That was caused because the driver kept
polling the (physically unconnected) digital inputs.
[note: a workaround for drivers without this patch
is to zero the 'xpd_fxs.poll_digital_inputs' parameter.]
* Also, the digital_inputs/digital_output masks were
calculate using a different condition.
* Now we determine number of channels, digital inputs and
digital outputs in a single place and use this info
later to calculate the correct masks.
* We poll only if there are digital_inputs
* We added a sanity check in process_digital_inputs, so
we get a notice if it's called on an xpd without digital
inputs (e.g: hypothetic firmware bug).

DAHDI currently waits a second before checking if a board driver is
calling dahdi_receive and switching to internal timing. Some versions of
Asterisk (I was looking at 1.4.42 when writing this) only wait 300ms for
a timer to expire when first starting and verifying that DAHDI is
properly configured. This can result in a
"ERROR[27673] asterisk.c: Asterisk has detected a problem with your DAHDI
configuration and will shutdown for your protection. You have options:"
message if asterisk is started soon after loading DAHDI.
This change sets the inital polling interval to the same as that used
during normal coretimer operation, 4ms. The interval will still be
slowed to 1 second if a board driver starts calling dahdi_receive().
