Simplify the code generators by merging the two hash constant arrays
into one. The hash is effectively the same, although the order of the
constants differ (possibly in a way which makes the indexing easier.)
The main difference is the amount of code is necessary to generate
each of the output C files.

Add a generic facility for generating perfect string hashes, where all
that is needed is an enum and a string table. The existing mechanism
using a custom Perl script wrapped around a module continues to be
available for any use case where this particular approach isn't
sophisticated enough.
Much of this patch comes from renaming "enum directives" to "enum
directive" as a result of the string hash generator expecting a set of
uniform naming conventions.
