/* A string intern table.
*
* The intern table holds a list of strings. Given a new string, we
* either str_dup it and add it to the table or return a ref to the
* existing copy of the string from the table if present.
*
* This implementation has one big intern table that's designed to be
* used during db load then freed all at once. It might be
* interesting to intern all strings even during runtime. Somebody
* else can do this.
