Astribank 2.02: a newer model: slight variation of 2.01 (both use E-Main
4). Uses the same USB firmware, has to use a different FPGA firmware as
newer devices cannot be made to work with older 2.01 firmware.
FPGA rev. 11307.

* 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.

A new SysFS interface for FXS modules (XPDs):
* In /sys/bus/xpds/devices/<ll>:<m>:<n>/fxs_ring_registers
* Reading show current register values for NEON/TRAPEZ/NORMAL
* Modify the table via writing: "<column> <reg> <byte> [<byte>]"
* Example:
echo "NEON 0x33 0x12" > \
'/sys/bus/xpds/devices/00:0:0/fxs_ring_registers'

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 .

create_proc_entry() was deprecated and replace with proc_create_data() since
it's open to a race condition where the proc entry is visible before the file
operations have been set for it.
The PDE() macro also is no longer available as of Linux 3.10 and is replaced
with PDE_DATA() to get the data member from a proc entry. This is due to the
fact that 'struct proc_dir_entry' is now private to the proc_fs.
This commit changes the core of DAHDI and also introduces proc_create_data() and
PDE_DATA() for older kernels.

If a card stops generating interrupts for any reason, it can take awhile to
unload the driver while waiting for the commands to timeout. Now if there is a
problem, immediately set a bit that the card is failed so that no new commands
will be submitted.
Also, do not free and commands in submit since all commands are freed in get
results now. This prevents list/memory corruption when commands time out.

In 2.6.2 I introduced an error in (41639330a "wctdm24xxp: Eliminate chance for
channel to be stuck in RED alarm.") which would get an FXO stuck in detecting an
ONHOOK event from the remote side. An FXO port could go into the
BATTERY_DEBOUNCING_LOST_ALARM state and then back to the BATTERY_PRESENT state
without sending the dahdi_hooksig up to Asterisk. Therefore, Asterisk would
never detect the state changes needed for a remote side disconnect.
This change adds two more states, BATTERY_DEBOUNCING_PRESENT_FROM_LOST_ALARM and
BATTERY_DEBOUNCING_LOST_FROM_PRESENT_ALARM so that the state machine does not
miss any needed transitions when going back to BATTERY_PRESENT or BATTERY_LOST
regardless of why the debounce was started.

The channels now have embedded 'struct devices' that contain a device_private
pointer in which to store the device private data. When a device is
unregistered in the system the device privata data is freed by the device core,
even though the chan_release function doesn't free the memory
associated with the device, So when dev_set_drvdata() is called,
it's writing into freed memory.
We also need zero out the embedded struct device before registration,
since we do not have any guarantee that it points to valid memory (or, if a
channel was unregisterd with sysfs, and then reregistered without being cleared
out). Otherwise the core could try to use the previously freed private
data again.

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.
