C SUBPROGRAM:    EXITBUFR
C   PRGMMR: ATOR             ORG: NCEP       DATE: 2015-03-02
C
C ABSTRACT:  THIS SUBROUTINE FREES ALL DYNAMICALLY-ALLOCATED MEMORY,
C   CLOSES ALL LOGICAL UNITS THAT ARE OPEN TO THE BUFR ARCHIVE LIBRARY,
C   AND RESETS THE LIBRARY TO ALL OF ITS DEFAULT SETTINGS AS THOUGH IT
C   HAD NEVER BEEN CALLED.  THIS ALLOWS AN APPLICATION PROGRAM TO
C   POTENTIALLY RE-ALLOCATE MEMORY ALL OVER AGAIN WITHIN THE BUFR
C   ARCHIVE LIBRARY VIA A NEW SUBSEQUENT SERIES OF CALLS TO
C   SUBROUTINES ISETPRM AND OPENBF.
C
C   NOTE THAT ONCE THIS SUBROUTINE IS CALLED, THE ENTIRE BUFR ARCHIVE
C   LIBRARY IS UNUSABLE FOR THE REMAINDER OF THE LIFE OF THE
C   APPLICATION PROGRAM, UNLESS AND UNTIL SUBROUTINE OPENBF IS
C   CALLED TO ONCE AGAIN DYNAMICALLY ALLOCATE NEW ARRAY SPACE.
