The firmware load has been moved into a workqueue to prevent the module load
from blocking for the duration of the firmware upload. This could be up to 40
seconds. Driver prevents configuration until firmware load is finished and
is_initialized() returns true.

In previous releases of DAHDI if dahdi_cfg attached a software echocan
to a channel and a hardware echocan was available, the hardware echocan
would be used instead of the software echocan.
Since the 2.4 branch was created a new feature was merged into
dahdi-linux where it was possible to mix software echocan and hardware
echocan on a channel. This required using "hwec" as the echocan in the
/etc/dahdi/system.conf file so that what was specified in the
configuration file is what was actually used.
This has resulted in users upgrading to the trunk of dahdi without
updating their /etc/dahdi/system.conf file and just suddenly not using
any hardware echocans any longer.
The capability to mix software and hardware echocans on a span will be
revisted when running dahdi_cfg on any preexisting configuration files
doesn't just silently turn off hardware echocan.

This reverts commit r9891 and is part of two commits to revert all the
timer changes.
Grouping the timer into rates did not allow a timers rate to be changed
after another thread is already blocked on the poll call
The problem that was reported was if a sip call was made to a DAHDI
channel and the sip call was disconnected before answer, the DAHDI
channel would never stop rining.

r9946, "wcte12xp: Move the VPMADT032 test/configuration to module load
time." introduced a race condition where it was possible for the timer
that initiates the check for the alarms to fire before the board was
marked initialized. This would result in a board that would never again
check it's alarm state since the first time the timer runs INITIALIZED
may not be set and it will not reschedule a check since it believes the
driver is unloading.
This happened because the check for the VPM was moved between when the
timer was first setup and when INITIALIZED was then set.
Now we make sure INITIALIZED is set before the timer is first setup, and
move those two operations together.

In commit r9968 "wctdm24xxp: Allow more than one outstanding read at a
time" I introduced a regression where the transmit FIFO on the data
channel of a B400M could get locked up. The result would be constant
HDLC overflows when writing to the data channel.
This regression did not make it into any releases and did not exhibit
itself when crossing spans on a single B400M module. This is a partial
revert of commit r9968.

We can already use the module type to determine presence of a module to
check. This also moves the background polling of the modules until after
the board is completely initialized because the module type may change
while the different types are being probed. This also means that we need
to preset the shadow registers for the FXS because otherwise the shadow
register will not have been read before the first time it's checked for
a power alarm.

Part of increasing system startup speed.
Splitting these two operations facilitate checking if there is a module
present synchronously on driver load from the actual load of the firmware and
configuration of the channels.
This will allow the presence of the VPM module to be flagged on the span
before registration, but load and configuration can happen in the background.
When the modules are eventually loaded via udev, there will be enough time
from the time the drivers are loaded to when dahdi_cfg will run to complete
the firmware load, eliminating the need to block the driver here.

The firmware load of the VPMADT032 was moved to startspan because a
quad-span card in the same system would would lock interrupts for
several seconds to load VPMOCT064/128 firmware. Now that the wct4xxp
driver no longer locks interrupts while loading its VPM module this
driver can move the VPMADT032 check/load back to module load time.
This is also required so that the presence of a hardware echo canceler
is marked on the span before it is registered with dahdi-base.c.

dahdi_ec_chunk is the function that saves the received audio and places
a signed linear copy of it in the pre echocanceled buffer on the
channel. By splitting the input and output of this function into two
parameters, a driver that can provide separate pre and post ec streams
can pass them independently to DAHDI, without worrying about DAHDI
overwriting a stream that may have already been echocanceled by the
hardware.
Previously, the dahdi_ec_chunk interface took a received audio buffer
and overwrote it after canceling the echo. Now the input and output
from the function are broken up in order to support hardware echocans
that have a different preechocan stream.

This change ensures that the dahdi_span_ops callbacks are not called
with any spinlocks held, and that the module is pinned in memory, and
also passes the struct file * pointer to the callbacks.
Passing the file pointer to the callbacks allows the board drivers to
check any flags on the file descriptor used to configure the
span/channel. The intent here is to allow dahdi_config to open the
/dev/dahdi/ctl file in a non-blocking mode in case there is a lengthy
processes that needs to happen as part of configuration.

If we always set maintstat to DAHDI_MAINT_NONE, dahdi_base will lose
track of what it thinks the current state of the span is.
For example, if you run
$ dahdi_maint -s 1 --loopback localhost
When t4_clear_maint is called, the current maintenance mode state,
'maintstat', is set to DAHDI_MAINT_NONE. So the next time you call:
$ dahdi_maint -s 1 --loopback off
dahdi-base.c will believe that the user is trying to set the maintenance
state from DAHDI_MAINT_NONE to DAHDI_MAINT_NONE and will not actually do
anything.
