This moves the version string into dahdi-version.c that is then linked into
dahdi-base.c and dahdi-sysfs.c. This speeds builds on slow computers since
dahdi-base.c and dahdi-sysfs.c does not need to be rebuilt if only the version
string is changing.

Fixes a regression introduced in r9611. Analog spans would never become
the master since the SPANSTART ioctl is not typically called on them,
and therefore they were never marked RUNNING. The result could be audio
problems.
I'm marking this as related to issue 13205 since it's generally all
related to how should the drivers select which span is the master. I
also mark as related to issue 16165 because the problems experienced are
a result of the same fundamental issue.

With the release of Linux 2.6.37, the Big Kernel Lock is now a compile
time option. This change adds a mutex around the one place in the code
that we already knew was dependent on the lock_kernel/unlock_kernel
calls for serialization and drops the other calls to
lock_kernel/unlock_kernel if CONFIG_BKL is not defined.
This is *mostly* the dahdi-no-bkl.patch with a few minor whitespace
changes, the global_dialparmslock made static, and a warning added to
let people know they are running an experimental configuration.

This fixes a regression introduced in r9603. That commit removed
DAHDI_CONF_DIGITALMON handling (which is used to natively bridge two

symptom of the regression is muted audio when Asterisk tries to natively

Move pseudo channel numbers up into a high range so that their presence
does not interfere with assigning channel numbers for the channels
implemented on spans. Otherwise, if a pseudo channel was opened up
before an expected span was registered, all the channel numbers in the
newly registered span would be bumped up one. This does limit the number
of real channels that a single system may have registered to 32K (but in
dahdi-linux 2.4.0 and below you were limited to 1024 channels anyway,
both real and pseudo).
Also, the string name of the Pseudo channel is now based off the
number of Pseudo channels and not the total number of channels.

allow it to be forced on or off globally for the driver as a compile

pointer to the device (or embedding of the device). I prefer a simple

This fixes a regression from r9609 that Tzafrir reported. If you
register multiple spans, then remove the first span and try to register
a new span with more channels then the old span, you could end up with
multiple channels with the same number.
This change ensures that spans are ordered and that channels on a span
are always contiguous and ordered in relation to the spans.
In previous released versions of DAHDI (2.4.0 and below) this condition
would result in spans that may not have contiguous blocks of channels.
So it fixes both a recent regression and improves the behavior.

The default tone lengths are compile time options and they were in
digits.h to make it easy for users to patch. Most of these settings are
potentially overridden from user space via the DAHDI_SET_DIALPARAMS
ioctl currently regardless of these settings.
In r9597 I moved digits.h directly into dahdi-base.c since I thought it
was broken out for sharing between compilation units as opposed to
ease patching.
I also changed the units of the default options to ms instead of in
samples. This way if the sampling frequency changes the user will not
need to update the defaults.

When a span goes into alarm it will look for a potential new master
span. For dynamic spans that are running their processing in the
sync_tick callback, the chan_lock will already be held. Therefore,
push the locating of a new master out to the global workqueue.
