Refactor CREATE/ALTER DATABASE syntax so options need not be keywords.
Most of the existing option names are keywords anyway, but we can get rid
of LC_COLLATE and LC_CTYPE as keywords known to the lexer/grammar. This
immediately reduces the size of the grammar tables by about 8KB, and will
save more when we add additional CREATE/ALTER DATABASE options in future.
A side effect of the implementation is that the CONNECTION LIMIT option
can now also be spelled CONNECTION_LIMIT. We choose not to document this,
however.
