1. nickserv/canonmail: new module …

   This module originated as a way to test email canonicalization during
   development, but it may also be helpful to services operators to test
   their canonicalizer configuration, especially if custom modules are used
   that may do non-obvious modifications to the given email.

2. misc/canon_domains: new email canonicalizer module …

   This module is mainly intended to handle email providers with multiple
   interchangable domains serving the same users on each.
   
   For now this is rather simplistic, requiring mappings to be defined in
   the configuration file and not supporting wildcards or anything fancier
   than "treat these domains as the same".
   
   All domains of a given provider will be mapped to the shortest domain to
   avoid having to handle the case of extending the length of an email
   address, possibly exceeding EMAILLEN.
   
   (Do note that nickserv/badmail currently does not interface with email
   canonicalization and domains need to be added to that list separately
   if they are to be denied.)
