Add hash_free_all() to factor common code of iterating over all
members of a hash to free them with a single nasm_free().
Split strtbl_find() into strtbl_find() and strtbl_add(). It is very
unlikely that the same call site will want to have both of these
functionalities, and in the end the code for the two functions are
surprisingly different.

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.

Make the source code easier to understand and keep track of by
organizing it into subdirectories depending on the function.
