Allow CREATE/ALTER DATABASE to manipulate datistemplate and datallowconn.

Browse Source 
Historically these database properties could be manipulated only by
manually updating pg_database, which is error-prone and only possible for
superusers.  But there seems no good reason not to allow database owners to
set them for their databases, so invent CREATE/ALTER DATABASE options to do
that.  Adjust a couple of places that were doing it the hard way to use the
commands instead.
