Mainly to quiet a sparse warning, but this could be a real problem on
some non x86 platforms.

Make setup_chunks static, eliminate a dynamic array in the interrupt handler,
don't cast away a memory region specifier, and don't initialize statics to 0.

Added as a workaround for a system which was not routing interrupts
properly and therefore is off by default. Candidate for reversion in a
couple of years. DAHDI-627.

Closes a small window of opportunity where system conditions prevent the
driver from servicing it's receive ring within the timeout period of a
request, and then in the middle of retrying the request (after the
request was already removed from the "waiting_for_response" list) the
driver process the response, it's possible for the driver to ACK the
response without ever pairing it up with the original request. The
result being that the DTE will then ignore our attempts to retry the
original request. DAHDI-430.

As of this writing codec_dahdi (Asterisk module) will not call 'read' on
a transcoder channel more often than it calls 'write'. When a
translation path is setup that will transcode from g723 to g729, write
is called every 30ms and each 'read' returns only 20ms of data. The end
result is audio that slowly becomes increasing delayed.
Since codec_dahdi calls the system read function with a buffer large
enough to hold more than one packet this can prevents packets from
backing up on the channel. DAHDI-582

Upon review the event introduced in r8998 seemed to be
redundant, as the same information was already available.
Performance issues were also a concern. This reverts r8998.

QuadFalc has the ability to test if the transformer is
performing correctly. If the components between the framer
and the physical span interface are shorted out or opened
for any reason we can now detect it. Possible causes for
tripping this error could be a broken transformer from
an electrical spike or a board manufacturing error.

When a loss of syncronization signal occurs on one of
the spans, it affects all spans on that card. Since we
do not have a span or card level event system, we have
to queue up a global event on all channels for that card
The new event is DAHDI_EVENT_SYNC

qfalc framer.
Added some more verbose red alarm states in the upper byte
of the alarm member of the dahdi_span structure
Removed some unnecessary instrumentation regarding the enabling
of the errored second and 1 second counters for performance
collecting. Also added a couple comments.

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.

The echo canceler will now monitor if the receive signal goes over a
certain threshold, and if so, freezes its adaptation to prevent loss of
convergence. I.e. Fixes conditions where blowing into your handset
could result in echo. Additionally, 1.25 includes improvements for
handling when line conditions change from echo free to containing echo.

In revision 8095, I had moved most of the buffer processing out of the
interrupt handler and into a tasklet. The intended result was to enable
multiple cards to interleave with one another. But once again I was
bitten by the fact that there are some systems that for one reason or
another do not process their tasklets in a timely enough manner for the
real-time nature of TDM processing. This commit moves this processing
back into the interrupt handler by default. It also limits the number
of frames that the interrupt handler will process at any given time
which appears to achieve the same intended result.
(closes issue #17289)

Will add an option to allow calling the deferred processing callback directly
in the interrupt handler. It appears there are some systems which still are
unable to process their tasklets in a timely fashion, especially if they get
pushed out to the ksoftirqd daemon.

* If we have vmwi_ioctl=N, we should initialize the vmwi_type
of all channels. We initialize it to HVAC
* Fix a regression, where curly braces around empty if()'s were removed.
* Also fix the VMWI_TYPE() macro, so it actually uses the 3'rd parameter.
(this didn't cause damage yet, as we only used HVAC so far)

This avoids most cases of sending garbage at startup by setting each port
to tristate mode at init time (in the init script) and enable it back at
DAHDI_STARTUO (end of dahdi_cfg).
Upgrade note: if you have upgraded the files (including init script) but old
module is still loaded, you may end up with the port not getting ever
enabled and the line practically dead. In such a case, reload the new module.

* Now get_xbus() receive and xbus number (not poiner) and uses xbus_num()
internally to map it to an xbus pointer + refcount increment. (this is
atomic)
* Migrate all obvious places that used xbus_num() to map bus number into a
pointer, so now they use get_xbus() + put_xbus() to aquire and release an
xbus.

* PRI devices always get SYNC-AB (never PLL, not even for NT)
* Fix Timing priority calculation accordingly.

* Astribank devices now reside under their own top-level device.
* The USB device is still used as the 'transport'.
* This means the astribanks parents are NOT the USB devices.
* As a result, even after a USB disconnect, we have valid sysfs representation.

* Supports only our current NEON notification.
* No more global 'vmwineon' parameter:
- We expect asterisk to tell us by channel.
- If 'vmwi_ioctl' is not set (it is by default), that we revert
to FSK searching (expensive) and call directly our NEON code
(as before).

Fixes a crash resulting from a race between disconnecting and connecting
Astribanks (on multi-core systems)
* Use get_xbus()/put_xbus() arround xbus_populate(), so a disconnect
in the middle won't release the xbus too early.
* Aquire all XPDs before starting initialization and release them
after it finishes (so we don't have up/down races among XPDs)
