It would not be a big deal to include svn_hash.h in the files that we're
modifying.  However, these can be considered just convenience wrappers around APR hash functions, like svn__apr_hash_index_key/klen/val which are
already declared in svn_types.h so that they are globally available without
having to include svn_hash.h (since virtually all files include svn_types.h already).  It makes sense to me to do the same with

This reminds me, I wonder if we're being premature in making these new functions public.

I'm not sure exactly what you mean, but if we do decide to leave the definitions in svn_hash.h and add '#include <svn_hash.h>' to each C file, that would be functionally equivalent to replacing one #include directive with the other, because of the include-guards.  I would oppose actually removing '#include <svn_types.h>' from the source files, as a matter of style.
