Improvements to the xpp tool dahdi_registration:
* Use the new xpp driver with support for dahdi_registration sysfs
attribute in each device.
* Wait for UDEV to finish handling span assignments (via
dahdi_waitfor_span_assignments).
* Still supports legacy drivers without this, by falling back
to old style iterative "registration" on each xpd.

* Don't use "usb_clear_halt" by default anymore
- It caused problems with specific devices in the past
- Now it cause problems with specific servers as well (64 bits, USB3)
* Add an "XTALK_OPTIONS" environment variable to pass options:
- Use it to implement a "use-clear-halt" boolean option that
restore original behavior.
- Also use it for "no-lock" option which replace the legacy
environment variable "XUSB_NOLOCK".
* Compile with "-Wall -Werror"
* Better dependency calculation:
- Explicit listing of sources, don't use wildcards.
- Pass various CFLAGS to dependency calculation as well.
- Make sure a failure is propagated

Single frequency signalling has not been supported in dahdi_cfg since the switch
to DAHDI. Before DAHDI, in the Zaptel days, it was only suported in the
ztcfg_dude utility which wasn't mainlined. So this removes references to those
signalling modes unless support is added back into the driver.

* The "spantypes" generator had E1 default if no 'line-mode' parameter
was passed.
* As a result the new logic in "dahdi_span_types dumpconfig" had no
effect when called from dahdi_genconf, as it was always called
with "--line-mode=" argument.
* Now "dahdi_genconf spantype" behaves just like
"dahdi_span_types dumpconfig":
- The "--line-mode=" forces generation of provided line-mode (E1/J1/T1)
- Without this option, the generated config matches the current spans
state according to new dahd_span_types default logic:
- Wildcard rule if all spans have same line-mode.
- Uncommented specific matches if spans have different line-modes.

Fixes a regression since 949ea4ca9f
(2.7.0) - allows using an Astribank with no serial.
* Some of the olderst Astribanks don't have a serial number burned in
them. Thus there is no serial attribute for the sysfs USB device node.
* waitfor_xpds identifies the Astribanks by their serial numbers.
* An lone Astribank without serial number would thus block waitfor_xpds
(until timeout).
* Now we warn about them.
* We also try to handle it gracefully. As long as there's only one
of thease, it would be counted as "NO-SERIAL".

* The system state causing the bug:
- DAHDI has auto_assign_spans==1
- No /etc/dahdi/assigned-spans.conf
* The bug scenario:
- During initial device detection, they are assigned by
DAHDI driver.
- Later we run "dahdi_span_assignment remove"
- Then, a "dahdi_registration on" would not assign any span.
* The fix:
- Using the '-R' option, force "dahdi_registration on" to also
do "dahdi_span_assignment auto" on relevant devices.
- This is the way it's called by /usr/share/dahdi/dahdi_auto_assign_compat

* Better defaults:
- A wildcard match:
- If '--line-mode' option is given, generate a wildcard entry.
(existing behavior).
- Otherwise, if *all spans* are of the same type (E1/T1),
generate a wildcard entry for this type.
This is the most common use-case and now it work without
any command line flags.
- Otherwise (mixed E1/T1 spans), do not generate a wildcard entry.
This isn't common case (except from our labs), but regardless
without '--line-mode' any guess could be wrong.
- Specific device matches:
- If all spans are of the same type, generate commented out
specific entries (for manual overrides).
- If spans have mixed E1/T1 types, generate specific entries
In this case, specific entries MUST NOT be commented out
otherwise, the configuration file is wrong!
* Generated header with better organization:
- Shows what is generated:
- Generating wildcard / Not generating wildcard
- Generating specific lines / Generating *commented-out* specific lines
- For each decision, show *why* it was taken.

Maintains the original registration order as was before span
assignments. Should allow seemless trannsition to
dahdi.auto_assign_spans=0
* The idea:
- We stop handling in udev the case of missing
/etc/dahdi/assigned-spans.conf
- Instead we rely on "registration_time" dahdi_device attribute from
DAHDI-linux
- Then, we can sort the devices and assign their spans in
/etc/init.d/dahdi
* Mechanics:
- From /etc/init.d/dahdi, we run a new 'dahdi_auto_assign_compat'
script (after "waitfor_xpds" etc.)
- In this script we "auto" assign spans of non-Astribank devices
- In the end of the script we run "dahdi_registration" which
does the same for Astribank devices.

Removes a potentially confusing error message. This is a reapplication of
(4f259cd569 "dahdi_handle_device, dahdi_span_config: Check for
auto_assign_spans only when ACTION is add.") which appears to have been
accidentally removed when moving the hotplug scripts into a subdirectory.
From the original commit:
When dahdi.ko is unloaded, it may be possible for the driver to be removed from
the kernel before the udev scripts are run. When this happens, you'll see
messages like the following which are not accurate:
'dahdi_handle_device'[24567]: Old driver (no auto_assign_spans parameter). Skip /devices/pci0000:00/0000:00:1e.0/0000:11:01.0/pci:0000:11:01.0
Now instead you will see:

This reapplies the change made in commit (6ed0adc08 "dahdi_span_config: Do not run auto
span configuration if spans are auto assigned.") which appears to have been
accidentally removed in (7f826a7d35 "hotplug modularization: split logic to
scriptlets").
To rationale from commit 6ed0adc08:
I have seen cases were users run:
# modprobe <driver>; dahdi_cfg -c <custom config file>
and the spans end up misconfigured because dahdi_span_assignments ends up
running, via udev, after the user configured the span the way it wanted.
dahdi_span_assignments now looks at auto_assign_spans module parameter on
dahdi.ko, like dahdi_handle_device already does, to determine if legacy or udev
based configuration is being done.

* Add '--line-mode=<E1|T1|J1>' option to dahdi_span_types:
- Will first generate a wildcard entry (* *:<type>)
- All later entries will be commented-out.
- Manually uncommenting any of them will create an "override"
(e.g: mixed system with all spans T1, but some E1)
* Now dahdi_genconf does not generate span-types.conf by default:
- Added '--line-mode=<E1|T1|J1>' option to trigger generation
- This parameter will be passed to "dahdi_span_types dumpconfig"
- Also explicit specification of 'spantypes' as an argument will
trigger a similar generation (with a default of 'E1').
- The line-mode may also be passed to the generator directly
with identical results. Example:

* Updated the man-page:
- Fixed "registered" => "assigned".
- Use "line mode" for E1/J1/T1.

Prior to this commit, if auto_assign_spans was set to 0, it was possible to
get in an endless loop creating and destroying spans. The primary reason was
that all dynamic spans are destroyed and recreated each time dahdi_cfg runs, BUT
dahdi_cfg was run each time a new span showed up in udev when auto_assign_spans
was set to 0.
Now dahdi_cfg will only destroy and recreate dynamic spans if dahdi_cfg is run
without a specifc span number. Also, while creating dynamic spans, dahdi_cfg
will pause for up to one second for the span to be assigned in order to ensure
that the spans are numbered consistently when auto span assignment is
configured.

When dahdi is configured for fully dynamic configuration on a device and
span basis via sysfs and udev it is possible for multiple instances of
dahdi_cfg to be run in parallel on different spans. If this happens it
is possible to see errors on the console that tone zones are already
registered since the check for the existence of a tone zone and the
re-registering needs to be atomic.
dahdi_cfg will now prevent itself from running in parallel.

When auto span assignment is disabled, it's possible that simply running
# /etc/init.d/dahdi restart
Will fail since dahdi_cfg can run in parallel with udev scripts that are
assigning spans, which results in /etc/dahdi/system.conf describing spans that
do not exist in the system.
This change sets up dahdi_cfg, when run without the -C or -S options, to look in
sysfs and make sure all spans for each device are assigned. dahdi_cfg will wait
