textproc/htmlc: fix build on powerpc

lang/ocaml: Update to 4.08.1

This update allows (and for some requires) to also update dependencies
to newer versions. Where possible I updated to the latest version.

The ocaml port now is MAKE_JOBS safe.

Changes to dependent ports included in this commit:

- devel/ocaml-sexplib: Rename to devel/ocaml-sexplib0 adapting to
  upstream. Update to 0.16.0
- devel/coccinelle: Update to 1.1.1, moved to github
- devel/ocaml-camlp4: Update to 4.08+1
- devel/ocaml-camomile: Use dune for build, adapt port
- devel/ocaml-cppo: Fix lib files installation [1]

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.

Approved by:		portmgr (tcberner)

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.

textproc: remove 'Created by' lines

Htmlc is an HTML template files expander that produces regular HTML pages from
source files that contain text fragments that require some computation to be
written. Those fragments can be the output of an arbitrary Unix command, for
instance the last modification date of a page, or parts of HTML pages to be
included in the page, or pieces of the page that are common to the entire WEB
site (a presentation header or a footer section for each page). Providing the
automatic inclusion of those text fragments into your HTML source pages, Htmlc
offers a server independent way of defining templates to factorize out the
repetitive parts of HTML pages. Htmlc also provides a variable expansion
facility (using definitions in the template file or in simple environment files
using a syntax a la objective Caml). In short, Htmlc ensures the static
verification and the static expansion of the Server Side Includes directives of
the Web pages in the efficient and friendly way of a command-line compiler.
