[Serdev] New make support: group_include in make

[Greger V. Teigre]

I have added support for group_include in make according to SER-177. I 
have followed Bogdan's naming suggestion and (after hearing no more 
objections ;-) included both stable and experimental as status groups.
Each group can thus have one of the following different status: 
standard, standard-dep, stable, experimental.
Below is the explanation from the make file and shows how the modules 
are currently defined.
Could you please review and give feedback on whether modules should be 
in other groups?

The new support is backwards compatibility (by leaving out group_include).

I have also created a new target print-modules that can be used to print 
out the resultant include_modules and exclude_modules, ex:
make group_include="standard" include_modules="acc_db" print-modules

Please refer to INSTALL file for more info on using the new 
group_include.  Please note also that once the status of the modules 
have been set in each group, I will update the module status found in 
the online module documentation http://iptel.org/views/moduledocs and 
that after that any changes to the groups found in Makefile should also 
be followed by an update of the status on
g-)
