Eliminate the patch, initscript, and systemd tarball maintained out

Eliminate the patch, initscript, and systemd tarball maintained out
of tree, and:
  - Fix bug 460956 by changing directory mask to 1775 which allows
    all to access sockets, users within the group to create a socket,
    and restricts the deletion or modification to the socket owner or
    directory owner.
  - Fix bug 488246 by creating symbolic links to the configuration
    files when PGDATA and DATADIR differ.
  - Fix bug 511942 by warning if CONFIG_SYSVIPC is not enabled.
  - Fix bug 518522 by appending the plperl.on_init workaround to
    postgresql.conf. (This only affects new installs.)
  - Fix bug 529680 by removing the autotools inherit, and removing
    the sed statement. We don't change anything in configure.in, which
    means we don't need to regenerate the configure script.
  - Fix bug 530790 by correcting the typo.
  - Fix bug 531820 by removing the pre-initdb tests.
