Update pspp to 0.3.0

Version 0.3.0 changes since 0.2.3:

  Bugs fixed:
    * Using alphanumeric variables in functions under AGGREGATE
      segfaulted.  Fixed.
    * Under certain circumstances, the final case would be omitted
      from the results of an AGGREGATE operation.  Fixed.
    * Undefined behavior was invoked by referencing a freed pointer
      under certain circumstances.  Fixed.
    * A wrong record size was displayed when paging the active file to
      disk.  Fixed.
    * Not having enough temporary space for sorting caused a core
      dump.  Fixed.
    * Syntax errors in function descriptions on AGGREGATE caused core
      dumps.  Fixed.
    * A null pointer was dereferenced, causing a core dump, when
      PERCENTILES was specified on FREQUENCIES.  This fixes the
      problem, but PSPP still doesn't calculate percentiles.
    * SORT always sorted in ascending order.  Fixed.
    * Some minor memory leaks in the expression parser were removed.
    * Many assertions fixed for strict ANSI C compliance.

  New features:
    * SET ECHO ON now implemented, but turned off by default.
    * PRINT specifier supported on END REPEAT.

  Other:
    * System libgmp2 library is used if installed instead of
      unconditionally using the included libgmp2 subset.
    * Extensive code cleanup, which continues.
    * Added CORRELATIONS command parser, but not implemented.
