I'm fine with that.

I don't think I've got the appropriate karma to commit to APR, so whoever commits this patch
can make that change (or would it be worse the hassle for me to create a new patch?).

I'm also planning a followup which const-ifies the apr_hash_index_t params to these functions,
as well as apr_hash_this().  Thoughts?
