This resolves an issue with a Glenayre GL3000 Paging Terminal with v8.000
software. The Glenayre would change both A and B bits to signal on/off hook
states, but there were a couple of milliseconds between when those bits changed.
This resulted in DAHDI generating an on-hook event to Asterisk before generating
the off-hook event and therefore Asterisk terminated the call prematurely.
Looking the A and B bits before this patch:
Asterisk (AB) Glenayre (AB)
00 00 Both sides on-hook
11 00 Asterisk goes off hook to sieze line.
11 01 Glenayre starts going-offhook. On-hook event
sent to Asterisk from drivers since bits
changed but ABIT was still 0.
11 11 Glenayre finishes going off-hook. Off-hook
event sent to Asterisk since ABIT changed
from 0 to 1.
00 11 Asterisk, processes on-hook event and goes
on-hook itself to release line.
00 00 Glenayre releases line. Call fails.
After this patch:
Asterisk (AB) Glenayre (AB)
00 00 Both sides on-hook
11 00 Asterisk initiates call
11 01 Glenayre starts handling call. No event is
sent to Asterisk since only ABIT is checked.
11 11 Glanayre finishes going off-hook. Call
proceeds normally.

Since r5021 [1], first released in DAHDI-Linux 2.2.0, it's been impossible for
user space to change the rxbufpolicy. This hasn't caused any problems and it's
safe to remove a few more of the vestiges of the rxbufpolicy from the driver.
This streamlines the code path in a few places and saves 8 bytes from the size
of struct dahdi_chan.
The user visible parts are maintained and will indicate
DAHDI_POLICY_IMMEDIATE, like it has since 2.2.0.

Since r10683 "convert span->spantype to enumerated type" [1] the spantype was
changed from a string provided by the board drivers to an enumerated type that
is handled by the core of DAHDI. This was done to simplify the task of
dahdi_genconf since there is only one place to look for the valid strings that
can be exported in sysfs.
This eliminates the following warning on driver load:

Internally in DAHDI there is always a hardware echocan factory registered and
available. Having this factory always registered allows for DAHDI to work in a
backward compatible fashion. Namely, by default DAHDI will always use a hardware
echocan if one is available unless 'hwec_overrides_swec' dahdi module parameter
is set to 0 on load. However, if there were no real hardware echocans available
in the system dahdi would still report "Echo Canceller(s): HWEC" in the
dahdi_cfg -v output since the hwec factory is always there.
After this change dahdi_cfg will no longer report HWEC as one of the available
echocans if there isn't a physical span present that actually has a hardware
echocan.

When DAHDI is bridging channels between two different cards, or a user is trying
to record from a channel on a card that is not using the same timing source as
the master span, it is possible to miss audio.
For example, given the following scenario:
<T1 Span> <---> <ISDN CARD> <---> <ANALOG CARD> <---> <local handset>
If DAHDI was set to natively bridge the call from the T1 span to the local
handset it is possible that system conditions could result in one of the cards
servicing their interrupt three times before the other card has a chance to.
Since there are currently only two conference buffers to pass audio between the
cards, one chunk (1ms) of audio will be dropped since the card servicing it's
interrupt more frequently will run out of space to copy audio for the other card
and will have emptied the audio buffer from the other card.
Increasing the number of conference buffers to eight greatly reduces the
probability of audio from being dropped under these conditions at cost of an
additional 72 (32-bit) or 96 (64-bit) bytes per DAHDI channel.

This fixes a regression introduced in commit r10186 "wctdm24xxp: Use time
interval for debouncing FXO ring detect." [1] which was first released in
DAHDI-Linux 2.6.0. This only affects users with analog trunks whose providers do
not present 4 polarity reversals on the ring signals. The reporter of this issue
is based in South Africa.
[1] http://svnview.digium.com/svn/dahdi?view=revision&revision=10168
In prior versions, the ring detector did not check for polarity reversals, only
the presence of ringing voltage unless fwringdetect or neonmwi_monitor mode was
set, and even when one of those modes were set, the driver only needed two
reversals to validate a ring. This commit allows the driver to always stay in
fwringdetect mode but restores the requirement for only two reversals.
Also included in this commit is a change to ensure that ringing is not reported
when debouncing lost battery which can happen when voltage is swinging through
0.

Now instead of using an array on the stack, of which all elements were not used,

The frequency that the RBS registers were polled was too slow to catch the pulse
dialing digits. The result was that often times dahdi would generate WINK events
instead of PULSEDIGIT events.
This speeds up the rate at which the registers are checked from 100ms to 33ms
and also makes the process of checking the registers quicker by queing up all
the reads at once.

To enable J1 mode previously one would configure the card in T1 mode and then
set the j1mode module parameter. Now "modprobe wcte12xp default_linemode=j1"

J1 can also be set on a card-by-card basis in sysfs.

This is a port of the functionality in the wctdm24xxp driver to support power
savings modes. Specifically, if the the network side of a BRI spans deactivates
the span to save power, the B410P previously automatically activated it again.
Now, if persistentlayer1=0 module parameter is set, the span will be allowed to
stay deactivated until layer two has a message to send on the dchannel.
This patch does not change any of the default behavior of the B410P driver and
the defaults for the persistentlayer1 option is inconsistent with that of the
B400M modules in the wctdm24xxp driver.

It appears that some kernel configurations do not include timer.h in any of
the include files that are included by dahdi_dummy. The timer_structs are
defined in timer.h and not time.h, so this change is correct even though I
never could find a configuation myself that actually failed to compile.
This has negligible impact since dahdi_dummy is not compiled by default.
