Log message:
        Work around the fact that GDBM's firstkey/nextkey interface doesn't
        return ordered results.
        
        * libdb/db_gdbm.c (man_gdbm_open_wrapper): New function. Wraps the
        return value from gdbm_open() in a structure that remembers the
        file name.
        (parent_sortkey_hash_free, sortkey_hash_free): New functions to
        free hashtables used here.
        (sortkey_compare): New comparison function for qsort().
        (man_gdbm_firstkey): New function. Retrieve all keys using
        gdbm_firstkey() and gdbm_nextkey() in advance, sort them into an
        ordered hashtable, remember that hashtable for later, and return
        the first key.
        (man_gdbm_nextkey): New function. Find the previously remembered
        ordered hashtable and return the next element from it.
        (man_gdbm_close): New function. Clean up remembered data.
        * libdb/db_lookup.c (copy_datum): Define even if using GDBM.
        (gripe_lock): Explain why this isn't used for GDBM.
        * libdb/mydbm.h (man_gdbm_wrapper): New type.
        (man_gdbm_open_wrapper, man_gdbm_firstkey, man_gdbm_nextkey,
        man_gdbm_close): Add prototypes.
        (MYDBM_FILE): Change to man_gdbm_wrapper for GDBM. Adjust all
        other MYDBM_* macros to cope with this and use man_gdbm_*
        functions where necessary.
        (copy_datum): Declare for all database types. Remove __inline__.
        * docs/NEWS: Document this.
