      Bug#14603714: CRASH OBSERVED IN SQL_ACL.CC WHILE FREEING
                    UP THE MEMORY
      
      Description: In sql_acl.cc server_mpvio_info() calls
                   X509_NAME_oneline() function. This functions
                   returns pointer to a char string.When mysql
                   is using OpenSSL, OpenSSL library uses
                   OPENSSL_alloc() function to allocate memory
                   for char string. However in sql_acl.cc,
                   memory is freed using free(). Correct way to
                   free such memory is to call OPENSSL_free()
                   function. This change addresses this issue
                   and replaces call to free() with
                   OPENSSL_free() when memory is allocated through
                   X509_NAME_oneline() in sql_acl.cc.

      Description:
      -----------
      After compiling from source, during make test I got the following error:
      
      test main.loaddata failed with error
      CURRENT_TEST: main.loaddata
      mysqltest: At line 592: query 'LOAD DATA INFILE 'tmpp.txt' INTO TABLE t1
      CHARACTER SET ucs2
      (@b) SET a=REVERSE(@b)' failed: 1115: Unknown character set: 'ucs2'
      
      I noticed other tests are skipped because of no ucs2
      main.mix2_myisam_ucs2                    [ skipped ]  Test requires:'
      have_ucs2'
      
      Should main.loaddata be skipped if there is no ucs2
      
      How To Repeat:
      -------------
      Run make test on compiled source that doesn't have ucs2
      
      Suggested fix:
      -------------
      the failing piece of the test should be moved from mysql-test/t/loaddata.test to
      mysql-test/t/ctype_ucs.test.
