Fix WWW in parent/child ports

Many of the WWW are overwritten later which means the wrong value
is used. This did not happen before where the children were either
 a) just using the pkg-descr from the parents
 b) or had their own separate pkg-descr with custom WWW

Use WWW?= in parents when the child's WWW is different.

Children that use the same WWW as the parent can just inherit it,
i.e., the child WWW can be removed.

Remove WWW entries moved into port Makefiles

Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.

This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.

Add WWW entries to port Makefiles

It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.

Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.

There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.

Update libproxy and its slave ports to 0.4.12.

After being dormant since 2013, libproxy development picked up some steam at
the end of last year, and the project moved from Google Code to GitHub,
where its releases are also being hosted. A summary of changes between 0.4.6
and 0.4.12 can be found here:
    https://github.com/libproxy/libproxy/blob/0.4.12/NEWS

The libproxy ports themselves have undergone several changes too:
* net/libproxy
  - Drop a lot of patches that are no longer necessary.
  - Add a few patches that I have sent upstream, and add some context to the
    0.4.6 patches that are still required.
  - Explicitly disable a few build options (.NET bindings, for example).
  - Switch to an out-of-source CMake build (also applies to the slave

Change the way Perl modules are installed, update the default Perl to 5.18.

Before, we had:

  site_perl :           lib/perl5/site_perl/5.18
  site_perl/perl_arch : lib/perl5/site_perl/5.18/mach
  perl_man3 :           lib/perl5/5.18/man/man3

Now we have:

  site_perl : lib/perl5/site_perl
  site_arch : lib/perl5/site_perl/mach/5.18
  perl_man3 : lib/perl5/site_perl/man/man3
