Jul 2015 feature release

   MonetDB5 Server
     * Implemented batcalc.min and batcalc.max. Made calc.min and calc.max
       generic so that no other implementations are needed.
     * Removed function batcalc.ifthen.

   Build Environment
     * Upgraded the license to the Mozilla Public License Version 2.0.

   Client Package
     * Added a new output format to mclient: --format=expanded (or -fx).
       In this format, column values are shown in full and below each

   MonetDB Common
     * BUNtvar and BUNhvar macros no longer work for TYPE_void columns.
     * Changed interfaces of a lot of GDK-level functions. When they
       modify a BAT, don't return the same BAT or NULL, but instead return
     * Changed a bunch of hash-related functions to work on the tail
       column. The functions that have been changed to work on the tail
       column are: BAThash, BATprepareHash, HASHgonebad, HASHins, and

   Java Module
     * Improved JDBC driver to not throw NullPointerException anymore when
       calling isNullable() or getPrecision() or getScale() or
       getColumnDisplaySize() or getSchemaName() or getTableName() or
       getColumnClassName() on a ResultSetMetaData object.
     * We now compile the Java classes using the latest Java 1.8 version,
       and we tell it to compile for Java 1.7.

     * Differences between time, timestamp, and date values now return
       properly typed interval types (second or month intervals) instead
       of integers.
     * Added support for 128-bit integers (called HUGEINT) on platforms
       that support this.
     * Removed support for the mseed library.
     * Removed support for RDF.
     * Removed DataCell. It was experimental code that was never enabled.
