Subject: Conf: Allowing keyword redefinition

Some tokens are both keywords and symbols. For now, we allow only
specific keywords to be redefined; in future, more of the keywords may
be added to this category.

The redefinable keywords must be specified in any .Y file as follows:

  toksym: THE_KEYWORD ;

See proto/bgp/config.Y for an example.

Also dropped a lot of unused terminals.
