Update p5-BerkeleyDB from version 0.25 to 0.26.

Change log:

0.26  10th October 2004

        * Changed to allow Building with Berkeley DB 4.3

        * added cds_lock and associated methods as a convenience to allow
          safe updaing of database records when using Berkeley DB CDS mode.

        * added t/cds.t and t/pod.t

        * Modified the test suite to use "-ErrFile => *STDOUT" where
          possible. This will make it easier to diagnose build issues.

	* -Errfile will now accept a filehandle as well as a filename
          This means that -ErrFile => *STDOUT will get all extended error
          messages displayed directly on screen.

	* Added support for set_shm_key & get_shm_key.

	* Patch from Mark Jason Dominus to add a better error message
	  when an odd number of parameters are passed to ParseParameters.

	* fixed off-by-one error in my_strdup

	* Fixed a problem with push, pop, shift & unshift with Queue &
	  Recno when used in CDS mode. These methods were not using
	  a write cursor behind the scenes.
	  Problem reported by Pavel Hlavnicka.
