Some of the card callbacks needed maintstat set when processing loopup codes
from the remote side. This change is a modification of commit: (6c02c3c
"dahdi-base: Minor maint mode error")
Without this change cetain cards would not properly process the loopup /
loopdown codes (I know I should have more specific information here but the
details escape me at the moment).

This is mostly a revert of commit r9463. If you need to use DAHDI_CONFLINK
ioctl, make sure to define CONFIG_DAHDI_CONFLINK in
include/dahdi/dahdi_config.h. Apparently there were some users of CONFLINK out
there still.
It's a compile time option now since most users won't need to run the test for
conflinks in the hot-path that is the process_masterspan function.

On SMP systems there isn't a need for all dahdi timers to
synchronize on dahdi_timer_lock. Instead give each timer it's own
lock to synchronize with process_timers and use dahdi_timer_lock to
protect the global list of locks.
Also, the dahdi_timers list now only contains timers that are set to
fire. This eliminates a test for each timer in the hot path of the
process_masterspan context.
Reduces system load on many-core systems which are heavy users of
DAHDI timers.

There was a code patch where it was possible to get stuck in RED ALARM on a
channel when debouncing the battery states. The state transitions would look
like this:
BATTERY_PRESENT -> BATTERY_DEBOUNCING_LOST -> BATTERY_DEBOUNCING_LOST_ALARM --
(send alarm up to asterisk) --> BATTERY_LOST -> BATTERY_DEBOUNCING_PRESENT ->
BATTERY_DEBOUNCING_PRESENT_ALARM -> BATTERY_DEBOUNCING_LOST -> BATTERY_PRESENT
In the above sequence there was never any transition from
BATTERY_DEBOUNCING_PRESENT_ALARM to BATTERY_PRESENT so the alarm to Asterisk was
never cleared and the channel stayed stuck.
Now when you loose battery when in the BATTERY_DEBOUNCING_PRESENT_ALARM go all
the way back to the BATTERY_LOST state instead of the BATTERY_DEBOUNCING_LOST
state so that all the events are properly sent up.
This fixes a regression introduced in 2.6.0 with commit (r10169 "wctdm24xxp: Use
interval for debouncing FXO battery." 874b76bd22).

It's wrong (and explicit oops with kernel >= 2.6.19) to set both
bus and class for the same device. But setting the class is not needed
in order to create a device. So just remove our dynamic devices from the
dahdi_class. It will only contain the fixed-named devices.

The driver iterates through all the spans on a given device during assignment,
checking for unassigned spans, but it was erroneously testing the span on which
assigned was called.
This just removes some unexpected behavior and provides a slight performance
increase on load and does not impact the functionality of the driver as far as
I'm aware.

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:
