Merged from trunk -r13387:13391

   | 13388   | Set executable.                                              |
   | zmedico |                                                              |

   | 13389   | Add dohard and doset helper which die for EAPI 3. TODO: Make |
   | zmedico | the die helper use pipe or socket IPC instead of a signal,   |
   |         | to avoid a potential race condition in signal delivery.      |
   |         | Thanks to to Tiziano Müller <dev-zero@g.o> for the initial  |
   |         | patch.                                                       |

   | 13390   | Add dummy dosed and dohard functions for EAPI 3, so that a   |
   | zmedico | trace can be displayed (not possible with the helper         |
   |         | binaries).                                                   |

   | 13391   | Revert r13390 (dosed and dohard functions) since a stack     |
   | zmedico | trace isn't really important this particular QA feature.     |
   |         | Thanks to Tiziano Müller <dev-zero@g.o> for the suggestion. |
