Use generic lists for recurring item exceptions.

Browse Source 
Rename "days" structure to "excp" which seems to be a better name here.
Use generic linked lists of excp structures instead of using the "days"
structure which again contains a linked list implementation. Do some
cleanups and invocation fixes.
