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.

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.

Since there isn't a fixed array to hold all the channels, and also limit
the total number of channels that can be created, we'll add a module
parameter to allow the system administrator to specify the maximum
number of pseudo channels. This is to prevent a potentially
non-privledged process from consuming too much CPU (since all pseudos
are checked each "tick" for conferencing) and kernel memory.
By default the number of pseudo channels is limited to 512. Change the
default limit with:
]# modprobe dahdi max_pseudo_channels=<new limit>
or at runtime with:
]# echo <new limit> > /sys/module/dahdi/parameters/max_psuedo_channels

This change primarily is a memory reduction. Most users only ever have
a single tone zone loaded so we can save some mostly unused pointers by
using a list instead of an array. Since we also have a pointer to the
dahdi_zone in struct dahdi_chan, we also don't need to store the integer
that is an index into that array. This saves 4 bytes for every channel
allocated in the system. Finally, we don't need a separate default_zone
member since we're on a list, we can define the first element on
the list to always be the default zone.
Additionally, all reference counted structures in the drivers should
standardize on kref as much as possible for simplicity.
