* Check NUMKEYS(), similar to f34b61f9
  "ITS#8722 fix FIRST_DUP/LAST_DUP cursor bounds check".
* Move XCURSOR_INITED() into XCURSOR_REFRESH().  This adds a check in
  mdb_cursor_put, below /* converted, write the original data first */.
* Factor mc_ki[] out to XCURSOR_REFRESH().
* Replace an mc_pg[] with mp which is equal (mdb_cursor_del0).

Fully revert the change to GET_MULTIPLE

GET_MULTIPLE was broken

Allow C_EOF flag to be stale

Optimize mdb_page_search_root(PS_LAST) when cursor is already near
last position, ignoring C_EOF flag for now.

Doesn't have POSIX robust mutexes - GNU userland on BSD kernel

- DISTRIBUTE_GROUP_DOC makes doxygen give several fields the
  same doc: mn_hi + mn_lo in MDB_node.
- With mdb_mutex_t + mdb_mutexref_t, instead split them up.

Never clear mc_error, we could lose a failure in the other thread.
