Description:
After a merge from mysql-5.1-bugteam, rpl.rpl_get_master_version_and_clock started to fail under valgrind in mysql-trunk-merge.

When I run the entire rpl test suite, it fails as in PB2:

rpl.rpl_get_master_version_and_clock [ fail ] Found warnings/errors in server log file!

When I run just rpl.rpl_get_master_version_and_clock alone, it fails with a different error:

rpl.rpl_get_master_version_and_clock 'mix' [ fail ]  Found warnings/errors in server log file!

      Fix for Bug#53925 (valgrind failures in rpl.rpl_get_master_version_and_clock
      in mysql-trunk-merge).
      
      There were two problems:
        - a mistake during merge of a patch for Bug 52629 from 5.1;
        - MTR treated auxilary output of newer valgrind as an error.
      
      The fixes are:
        - Fix merge error;
        - Teach MTR to skip 'HEAP summary' section of valgrind output.
