Summary:                    [patch] bad master selection
Description: 
Current dahdi master handling work in the following way:
The first SPAN become a master
If a new registered !!! SPAN is preferred , it is the new master
If a span is unregistered - the new master is the first available span
If master SPAN is in alarm state - the new master is the first non in
alarm state SPAN

So
1. dahdi-dummy once loaded will be the master forever.
2. even not-running SPAN can be a master
3. master implementation is ugly...

If you feel my suggestions is good - let me know, I'll produce a patch and
will test it on a hardware before posting.
I't prefer to implement STEP1, then STEP2.

STEP2 will also require to patch dahdi_dynamic (remove checkmaster
function, as long as it's going to be implemented in dahdi-base in a good
way).
Then there will be only one checkmaster in the whole DAHDI driver, as it
must be in TDM system.

I don't want to make produce patches if you don't like the idea :-)
