Update to 5.8.6. Also:

- redirect output from h2ph to /dev/null [1];
- fix File::Path insecure file/directory permissions [2];
  this resolves CAN-2004-0452
  (http://vuxml.freebsd.org/c418d472-6bd1-11d9-93ca-000a95bc6fae.html);
- for OSVERSION < 500036, create symlinks in /usr/bin not only for
  perl and suidperl, but also for a2p, c2ph, find2perl, h2ph, h2xs,
  perlbug, perlcc, perldoc, pl2pm, pod2html, pod2latex, pod2man,
  pod2text, s2p, and splain;  perl and suidperl are still enough for
  more recent FreeBSD versions [3];
- clean up created symlinks upon deinstallation [4];
- try to cleanup symlinks created by older versions of lang/perl5 and
  lang/perl5.8, during both installation and deinstallation [5];
- added support for DISABLE_BSDPAN environment variable [6];
- be explicit about use.perl usage after installation of 4.X systems
  [7];
- respect __MAKE_CONF partially (the build-time value is used) [8];
- fix threaded build - respect PTHREAD_CFLAGS and PTHREAD_LIBS [9].
- use.perl is now the same as pkg-install is now the same as
  pkg-deinstall;  apart from the changes already mentioned above, this
  is a shell script now;
- use.perl's logic is also simplified in several ways [10];
- fix a BSDPAN bug [11].

Outstanding issues: Module::Build support for BSDPAN, SU_CMD support (PR
70831), PR 64963 (partially), and anything else that I forgot.
