    features/changelog: Change barrier notification mechanism

    Backport of http://review.gluster.org/#/c/14272/

    The barrier notification mechanism was fd based and 'select'
    was being used. 'select' breaks when number of fds opened
    by brick process exceeds 1024. To avoid this and also
    the maintainance of pipe between notify and 'changelog_rollover',
    the pipe has been replaced with pthread condition signal
    and timed wait mechanism.
