* sourceforge.net/p/openipmi/code/commit_browser
    - 2.0.28 == 1666c8d5a4ee8874
    - 2.0.29 == 7a1d1ce556ce5d3d

  files/patch-unix_selector.c:
    - upstream reworked previous patch changes, we removed those changes;
    - patch was updated to handle the non-existing 'EBADFD' errno;
    - 'EBADFD' is Solaris/Linux specific, as per "bsm/audit_errno.h"
