devel/aifad: fix build on powerpc, update to 2.3.1

Changelog:	https://github.com/mmottl/aifad/releases/tag/2.3.1

Mk/**ocaml.mk: Convert remaining bsd.ocaml.mk to Uses/ocaml.mk

- Instead of USE_OCAML=yes use USES=ocaml. If empty USES=ocaml implies
  build and run
- Instead of USE_OCAMLFIND_PLIST use USES=ocaml:findplist which also
  implies USES=ocaml:findlib
- Instead of USE_OCAML_CAMLP4 use USES=ocaml:camlp4
- Instead of USE_OCAML_FINDLIB use USES=ocaml:findlib
- Instead of USE_OCAML_LDCONFIG use USES=ocaml:ldconfig
- Instead of USE_OCAML_WASH use USES=ocaml:wash
- Instead of NO_OCAML_BUILDDEPENDS use USES=ocaml:run
- Instead of NO_OCAML_RUNDDEPENDS use USES=ocaml:build
- Instead of USE_OCAML_TK use USES=ocaml:tk which actually implies
  USES=ocaml:tkbuild and USES=ocaml:tkrun
- Instead of NO_OCAMLTK_BUILDDEPENDS use USES=ocaml:tkrun
- Instead of NO_OCAMLTK_RUNDEPENDS use USES=ocaml:tkbuild
- USES=ocaml:dune remains unchanged
- Prepare to add/remove keywords easily

devel/aifad: Update to 2.3.0

PR:	280296

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.

devel: remove 'Created by' lines

devel/ocaml-cfg: update the port to version 2.2.0

This version is compatible with OCaml 4.06+ and allows to build
dependent `devel/aifad' port with minimal patching.  While here,
change the COMMENT to match upstream and flatten `pkg-plist'.

Remove # $FreeBSD$ from Makefiles.

Update OCaml to version 4.05.0 (this is the last version where strings
are unsafe by default, which is the main motivation why it was picked,
but not the very latest one) and synchronize the rest of the stack and
dependent ports with it, particularly:

  - Update `devel/ocaml-ocamlbuild' to version 0.14.0 and unbreak,
    register build dependency on all ports that require it (should
    be part of USE_OCAML, but we do not want to make any Mk-related
    changes the for time being)
  - Update `devel/ocaml-camlp4' to version 4.05+2
  - Update `devel/ocaml-camlp5' to version 7.07 (the project had
    moved to GitHub)
  - Mark `devel/ocaml-deriving-ocsigen' as BROKEN for now, it is
    very outdated and requires quite a lot of work
  - Update `x11-toolkits/ocaml-labltk' to version 8.06.3

Bump pcre library dependency due to 8.30 update

- Return my ports back to the pool.  I was unable to make any fixes to
  my ports in the past 3 weeks while ports were broken on any 10.x
  machines, which means I'm unable to maintain them.  So let people know
  that there's no available support for them until things are back to
  normal (which also means that anyone with spare time will be able
  to fix them without getting approval).

AIFAD stands for --Automated Induction of Functions over Algebraic
Datatypes-- and improves decision tree learning by supporting significantly
more complex kinds of data. This allows users to more conveniently describe
the data they want to have learnt, which can improve accuracy and complexity
of resulting models.
