- Add a new CONNECT global variable allowing to tell whether or not

  a temporary file should be used for UPDATE/DELETE of file tables.
  Also use the "sorted" argument of index_init to help decide if
  sorting of positions must be done.

- Add a new CONNECT global variable connect_exact_info. Set to ON, it
  tells CONNECT to return exact record numbers on info queries. If OFF
  it just gives an estimate. In version 10.0.13 this was unconditionally
  ON and caused info queries on remote tables to be extremely long and
  was the subject of MDEV-6612.
