If the driver is loaded with vpmsupport=0, then it was possible to create a
deadlock situation since the call into __dahdi_ec_chunk might then try to grab
the channel lock while already holding the reglock.
The purpose of grabbing reglock in the DMA routines was to protect the channel
array, which can be changed when linemode is changing. So instead, we'll
completely mask off that interrupt line from all CPUs when potentially changing
the channel array.

The octasic library is relatively large and is currently separately linked into
both the wcte13xp and wct4xxp libraries. This change moves it out into a
separate loadable module.
The bigest change from the drivers perspectives is that they must provide a
table of callbacks instead of using statically linked Oct6100UserXxxxx functions
to allow the library to communicate with actual parts on the cards.

dahdi_genconf currently does not take into account the number of spans
configured for a particular board. Therefore if you have two dual span cards
installed in the system, it could be possible to have something like this in
/etc/dahdi/system.conf:
spans=1,1,...
spans=2,2,...
spans=3,3,...
spans=4,4,...
When what you really want is something like this:
spans=1,1,...
spans=2,2,...
spans=3,1,...
spans=4,2,...
Otherwise, spans 3 and 4 will be configured to not recover the clock from the
span which is most likely NOT what you want.

* Our user-space previously used the implicit location from the sysfs
device path of the "dahdi_device".
* However:
- Sysfs paths are very limited in length.
- Low-level driver need more control on the location field.
- For example, it need to be persistant for span_assignments.
* We now export explicitly the 'location' field which is managed by
low-level drivers.
* We will use this field as the location in span_assignments.

xpp: refactor the FXS module ring settings into separate data structure:
* Update High VBAT initialization in init_card_1_30:
- Take the value used in set_vm_led_mode() (0x34)
- Now we don't need to set it over and over again in set_vm_led_mode()
* Create a unified ring_parameters[] array for all ring registers:
- Columns for 3 ring types (NEON, TRAPEZ, NORMAL)
- Used by new send_ring_parameters() function
* Now the set_vm_led_mode() simply calls send_ring_parameters()
* This cleanup would allow us to change ring parameters at runtime (by
updating the values in these tables).

With certain pci controllers that support pci hotplug, during the reset
sequence of the fpga, the host controller can get confused about the state of
the card and throw an nmi.
Known affected systems:
HP proliant DL160 & DL360p
Dell poweredge R520
Super Micro X7SPA-HF
This patch attempts to work around that by removing the fpga reset sequence
from the driver startup, then setting various control registers to known
starting state values.
This patch removes the field upgradeable firmware logic temporarily for the
te133 card to prevent fpga reset.

The make_version script would test for a .version file in the proper location,
but then would not properly read it. Since make_version is always reading the
.version script correctly now, the Makefile can be slightly simpilfied and
always defer to it.
This has no user impact since build_tools/make_version was never used to read
the .version file previously but will allow external scripts to use the
make_version script.

* In old kernels (e.g: 2.6.18) sysfs file names must be shorter
then KOBJ_NAME_LEN.
* Longer names are truncated and this leads to duplicate names
which fails device_register()
Examples: "dahdi!channels!10!10" is truncated to "dahdi!channels!10!1"
* The fix shorten the names and make them fixed length. Example:
"dahdi!chan!010!010"
* It seems no current userspace tools rely on that name or on
/dev/dahdi/channels .
