The name UNUSED is too generic and may conflict with future
macro definitions. This is machine-generated code anyway, so
rename UNUSED to UNUSED_HASH_ENTRY.

Clean up some perl warnings, some of which were legitimate (apparently
undef doesn't actually take a list of arguments, a common enough
mistake that it is mentioned in the man page!, and a list of variables
after "my" can be cantankerous), and some of which were nuisance but
were easy enough to clean up.
Maybe this can resolve the problems with very old version of Perl?

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.
