* We need to split the BRI D-Channel (HDLC) frames to smaller packets,
limitation of the FPGA.
* This changes batches BRI D-channel packets of the same HDLC frame to a
single XPP frame.
* Avoids an accidental fragmantion in case we were delayed for a few ms-s.
* Also improves efficiency.

* The zero lenth case (Magic request) was split into
send_magic_request() function. It was not possible
to move it into card_bri.c, because it is called
directly from the general interface we provide for
register read/write via sysfs/proc.
* The normal case (send_multibyte_request) was moved from
card_global.c into card_bri.c
* This sets the stage to enable bundling of multibyte
packets into frames (like we do for PCM).

Now that legacy BRISTUFF code is gone, some wrapper
functions became trivial. Removed these wrappers

Use similar caculation as in the PRI module:
* Save timing_priority from spanconfig and
elect syncer when spanconfig is called.
* Create custom timing_priority() function that returns
the value or error if span is disconnected.

* xpd_echo (card_echo.c) - a module to handle an Astribank hardware echo
canceller module.
* All other XPDs are now of type 'telephony_device'. Only a telephony device
XPD provides a span to register.
* The EC module will typically show up as XPD-40 and will always show up as
Unregistered in 'dahdi_hardware -v'

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.

gcc-4.6 now warns about variables that are set but never used. Clean up
unused variables everywhere except the oct612x subdirectory.
The oct612x should go in a separate patch in case that needs to be

Folded XPD_STATE() "protocol method" into the card_state() method.
It was only called from these (otherwise empty) methods.

* Caller to CALL_XMETHOD() no longer need to explicitly pass xbus
(calculate xpd->xbus)
* Create CALL_PHONE_METHOD() similar to CALL_XMETHOD() -- inlining
the extra parameters (more readable)
* Reverse parameter order in PHONE_METHOD() and CALL_PHONE_METHOD()
to be consistent with XMETHOD() and CALL_XMETHOD()
* Rename XPD_STATE phonedev method to card_state:
- Consistency with other phonedev methods.
- These calls now Wrap internal calls to XPD_STATE protocol HOSTCMD
in PRI, BRI, FXS, FXO

The vast majority of board drivers already keep the dahdi_span structure
in a driver specific structure. The others were easily converted. This
way board drivers can use the container_of macro to find what was
previously pointed to by the "pvt" member of the span. One less thing
to think about in the span structure.

Adds a struct module 'owner' member to the dahdi_span structure and updates
all the board drivers to set this member before registering the span. This
allows the core of dahdi to maintain the reference counts on the channels
itself.

As of 2.6.26 the macros dev_name() and set_dev_name() are used to read
and set (respectively) the bus_id member in sysfs. As of 2.6.30 bus_id
is gone. This patch provides comaptiobility macros for older kernel
versions and removes direct usage of bus_id.

The BRI module will now use hardhdlc unless the DAHDI tree has been
patched with the bri_dchan patch, in which case the old "bristuffed"
code will be used.
Thus it is now built by default.

* Fix cases where the command_queue overflowed during initialization.
* More migrations to sysfs:
- Add a 'transport' attribute to our astribank devices which
points to the usb device we use. E.g:
/sys/bus/astribanks/devices/xbus-00/transport is symlinked to
../../../../../../devices/pci0000:00/0000:00:10.4/usb5/5-4
- Move /proc/xpp/XBUS-??/XPD-??/span to
/sys/bus/xpds/devices/??:?:?/span
- Migrate from /proc/xpp/sync to:
/sys/bus/astribanks/drivers/xppdrv/sync
* PRI: change the "timing" priority to match the convention used by
other PRI cards -- I.e: lower numbers (not 0) have higher
priority.
* FXO:
- Power denial: create two module parameters instead of hard-coded
constants (power_denial_safezone, power_denial_minlen).
For sites that get non-standard power-denial signals from central
office on offhook.
- Don't hangup on power-denial, just notify Dahdi and wait for
- Fix caller-id detection for the case central office sends it before
first ring without any indication before.
Asterisk's desicion.

* Sysfs representation for XPDs:
/sys/bus/xpds/devices/<bus>:<unit>:<subunit>
* Astribanks sysfs directories now include the XPDs as subdirectories:
e.g. /sys/bus/astribanks/devices/xbus-00/00:3:0
* procfs control interface deprecated: conditioned by OLD_PROC
(defaults to off). Control functionality moved to sysfs:
* xbus attributes: cls connector label status timing waitfor_xpds xbus_state
* XPDs can have driver-specific attributes. Common attriubtes:
blink chipregs span
* PRI-specific attributes:
pri_clocking pri_dchan pri_cas pri_alarms pri_layer1 pri_localloop pri_protocol
* The Astribank attribute "xbus_state" is read/write. Reading it shows
the current state of the Astribank. Writing "start" or "stop" allows a
software equivalent of connect or disconnect respectively.
* When an Astribank is ready it sends an "online" event. Whenever its
not ready (e.g. at the time of disconnect) it sends an "offline" event.
Use astribank_hook.sample to handle those.
