devel/ocaml-topkg: fix build on powerpc

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

ocaml: Updates to ocaml compiler and several ocaml ports

- Update devel/ocaml to 4.14.2 [1]
- Specify runtime dependency on GNU AS as full path, this fixes
  build on armv6 - armv7 [1] [2]
- converters/ocaml-base64: Update to 3.5.1, add LICENSE, other
  improvements
- converters/ocaml-jsonm: Strip shared objects [3]
- databases/ocaml-dbm: Update to 1.3, move to gitlub, other

lang/ocaml: Update to 4.14.1

The 'force-safe-string; setting is NOT enabled, as opposed to the
new upstream default. OCaml users are encouraged to migrate to safe
strings as soon as possible.

- The X11 library isn't part of lang/ocaml anymore, users should
install x11-toolkits/ocaml-graphics.
- Add new 'ocaml' USES
- Bump PORTREVISION on dependent ports, due to ABI Change.

The update includes the following updates to existing ports (needed
to keep them working):

- devel/ocaml-camlp4: Updated to 4.14+1

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]

devel/ocaml-topkg: update the port to version 1.0.7

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.

*: bump PORTREVISION of all devel/xxhash users...

...except archivers/py-borgbackup, which requires a more complete fix.

devel: remove 'Created by' lines

converters/ocaml-jsonm: update the port to version 1.0.1 and

- Chase HTTP/1.1 301 redirection when fetching the distfile
- Update license (ISCL), assume maintainership of the port
- Use provided build scripts instead of performing it manually
- Convert to static pkg-plist, 16 lines don't warrant dynamic

devel/ocaml-uutf: (required) update the port to version 1.0.2
and make changes similar to the above;

devel/ocaml-topkg: call `do-build' recipe in ${BUILD_WRKSRC}.

devel/ocaml-topkg: new port had been added (+)

Topkg is a packager for distributing OCaml software.  It provides
an API to describe the files a package installs in a given build
configuration and to specify information about the package's
distribution, creation, and publication procedures.
