Redesign listeners using templates

This is actually just a start since it does not touch most of the
infrastructure for translators.


Contains the following commits in reverse order:



Remove Scheme listeners as they are just callbacks now.


Reimplement Listener around generic SCM callback and instance


Run preparatory script replacing listener macros

This script is

for i in $(git grep -l 'IMPLEMENT_LISTENER (')
do
    sed -i '/IMPLEMENT_LISTENER ([^)]*$/{N;s/\n\s*/ /}' $i
    sedscript=$(git grep -h 'IMPLEMENT_LISTENER (' $i|
		       sed 's|^.*IMPLEMENT_LISTENER (\([^,]*\), \([^)]*\)).*$| 
s/GET_LISTENER (\\([_a-z]\\+->\\)\\?\2)/\\1GET_LISTENER (\1, \2)/|')
    sed -i "$sedscript" $i
done
sed -i '/IMPLEMENT_LISTENER (/d' $(git grep -l 'IMPLEMENT_LISTENER (')
sed -i 's/DECLARE_LISTENER (\([^)]*\));\?/void \1 (SCM);/' $(git grep  
-l 'DECLARE_LISTENER (')

Make dispatchers callable for dispatching


Move self_scm_ into non-templated Smob_core base class.
