* contrib/sddsqlt3/core.c
    ! fix DBUSEAREA() operation with SQLITE3 SDD to return empty result
      when query conditions are false or the source table has no rows.

      Previously an logically correct example caused RTE:
      DBUSEAREA(,, "SELECT * FROM existing_table WHERE FALSE")

    ! fix double-free error in sqLite3Disconnect(), looks like the
      sqlite3_close() return value checking was reverted, SQLITE_OK is 0

    * use CDP API to get UTF8 string length

    * use new sqlite3_prepare_v3() when built against
      sqlite 3.20.0 or upper (change borrowed from Viktor's 3.4 fork)

    + add HB_SQLT3_MAP_DECLARED_EMULATED define (not yet enabled by default)
      which make this SDD additionally parse SQLite column declarations.
      Right now it can make HB_FT_DATE fields working using standard
      ISO 8601 "yyyy-mm-dd" syntax. Also declarations not significant for
      SQLite, but useful in xBase-style programming - SQL numeric(len,dec)
      columns are detected in this mode and will be reflected in dbStruct().

    + add support for alternative StoD() like syntax for HB_FT_DATE columns

    + add support for ISO 8601 "YYYY-MM-DD HH:MM:SS.FFF" timestamp declared
      columns, SQLite stored strings are converted to proper HB_FT_TIMESTAMP
      fields

    + added HB_SQLT3_FIELDNAME_STRICT define, which enables shortening
      of field to "name" if SQLite returns "table.name". Such fields are
      not completly usable in xBase code - WA->T.FIELD syntax is not
      valid, but FieldPos("t.field") is OK. I think it should be default
      behaviour or some runtime setting should be introduced for convenience
      when working with specific SQL queries.

  * contrib/rddsql/sqlbase.c
  * contrib/rddsql/sqlmix.c
    + added ZAP functionality to SQLBASE and SQLMIX RDDs,
      index tags are preserved while ZAP-ing SQLMIX area.
      They are cleaned, no REINDEX is needed

    * changed to allow values of any type in "V" SIX3 / HB_FT_ANY fields
      in SQLBASE/SQLMIX RDD workareas

  * contrib/hbfoxpro/relfunc.c
    ! fix InList() FoxPro compatible function not looking at the last
      parameter passed. Thanks to Attila Szabo for the information
      posted on the developers list.
