Always call GetModuleHandleW() with Unicode string, as mdb_fopen() is
calling CreateFileW() already.

Bump up number of keys for which we use fine-grained splitpoint search

Unnecessary since these are DUPs, the key will always be the same

Avoid stomping on flags from 1st readhr invocation

* 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

* Factor mc_ki[] out to XCURSOR_REFRESH().
* Replace an mc_pg[] with mp which is equal (mdb_cursor_del0).

Note about DB names being C strings

Return 1 if the cursor is pointing to a named DB record

Always save the terminating NUL of the incoming DB name
Stop using the old mdb_open/mdb_close function names
 .. should consider renaming mdb_stat/mdb_drop to mdb_dbi_... too.
