apr_table_t is a legacy type. Its basic characteristics are like a hash
table (mapping keys to values). However, the keys/values can *only* be
null-term strings. Multiple values are allowed, so it isn't *quite* a hash
table. The keys are case insensitive. And lastly, they are O(#keys) on most

In almost every case, when somebody uses an apr_table_t, they really meant
to use an apr_hash_t.
