   Merged from trunk 8873:8896

   | 8874    | Do an EBUILD_EXIT_STATUS_FILE sanity check in spawnebuild()  |
   | zmedico | where it spawns misc-functions.sh after the install phase.   |

   | 8876    | Add some documentation for ebuild phases and pre/post phase  |
   | zmedico | hooks that can be defined via bashrc.                        |

   | 8877    | Add a "Quality Assurance" tag so that all chapters are       |
   | zmedico | consistently nested inside tags.                             |

   | 8878    | * When installing a binary package, export the file name of  |
   | zmedico | the package as PORTAGE_BINPKG_FILE in order to give bashrc   |
   |         | users an opportunity to do various things such as remove     |
   |         | binary packages after they're installed. * Add a note in     |
   |         | ebuild.sh explaining why hardcoded bash lists are needed for |
   |         | backward compatibility with <portage-2.1.4 since they assume |
   |         | that a newly installed version of ebuild.sh will work for    |
   |         | pkg_postinst, pkg_prerm, and pkg_postrm when portage is      |
   |         | upgrading itself.                                            |

   | 8882    | First import the main portage module without legacy globals  |
   | zmedico | since it is almost certain to succeed in that case. This     |
   |         | provides access to the portage.exception namespace which is  |
   |         | needed for later exception handling, like if                 |
   |         | portage.exception.PermissionDenied is raised when            |
   |         | constructing the legacy global config instance.              |

   | 8883    | * Raise PermissionDenied from getconfig() when appropriate.  |
   | zmedico | * When available, make getconfig() include an invalid token  |
   |         | in a ParseError message.                                     |

   | 8884    | Instead of calling sys.exit when a ParseError occurs in the  |
   | zmedico | config constructor, raise a ParseError and make emerge and   |
   |         | portageq handle the error. This way consumers of the portage |
   |         | api can handle the ParseError rather than have their         |
   |         | application exit. Thanks to lxnay for reporting.             |

   | 8887    | Bug #198398 - Make repoman bail out if support for RMD160    |
   | zmedico | hash creation appears to be missing.                         |

   | 8888    | Fix the check for bug #198398 so that it works even when     |
   | zmedico | running repoman from the root of the repo.                   |

   | 8889    | Bug #202036 - In case of blockers, bail out earlier so that  |
   | zmedico | later code can assume there are no blockers.                 |

   | 8891    | In filter_readonly_variables(), replace 'declare -r ' with   |
   | zmedico | 'declare ' instead of removing it completely.                |

   | 8892    | Bug #202068 - In order to filter unwanted variable           |
   | zmedico | assignments out of the bash environment, use a               |
   |         | filter-bash-environment.py script that behaves similar to    |
   |         | egrep -v except that it leaves bash here- documents intact.  |

   | 8893    | Use the sed -r option to enable extended regular expressions |
   | zmedico | so that commonly used characters like (, ), and + don't have |
   |         | to be escaped.                                               |

   | 8894    | Bug #201848 - Mask ebuilds that do not define SLOT.          |
   | zmedico |                                                              |

   | 8895    | Bug #201848 - Make the ebuild command reject ebuilds that do |
   | zmedico | not define SLOT.                                             |

   | 8896    | Bug #201771 - Make unpack() detect common errors such as     |
   | zmedico | absolute paths that start with ${DISTDIR} and die an         |
   |         | appropriate error message. Thanks to grobian for this patch. |
