Mk/**java.mk: Convert bsd.java.mk to USES

The following features have been added or changed:
- Instead of USE_JAVA use USES=java. This defaults to
  USES=java:build,run if NO_BUILD is undefined. Else it defaults to
  USES=java:run
- Instead of USE_ANT=yes use USES=java:ant which also implies
  USES=java:build
- Instead of JAVA_BUILD=yes use USES=java:build. Does not imply run or
  extract
- Instead of JAVA_EXTRACT=yes use USES=java:extract does not imply
  build or run
- Instead of JAVA_RUN=yes use USES=java:run does not imply extract or
  build
- Instead of USE_JAVA=<version> use USES=java and JAVA_VERSION=<version>

math/scilab: drop maintainership

Release math/scilab and its prerequisites

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.

Clean up after java/openjdk6 and java/openjdk6-jre removal

java/openjdk6 support was removed from Mk/bsd.java.mk (r512662) and
java/openjdk6 and java/openjdk6-jre were removed from the ports tree
(r512663).  Now this patch completely removes remaining stuff from the
ports tree.

Take maintainership of math/scilab dependencies

Reassign makc's ports back to the pool.

See "Maintainer Reset" in
https://www.freebsd.org/portmgr/policies_contributors.html. makc's last commit
was in March 31st (r412218), and his ports have been timing out since at least
July (r418155).

I also emailed him 2 weeks ago and have received no response so far.

xml-commons is focussed on common code and guidelines for xml projects. The
first focus will be to organize and have common packaging for the various
externally-defined standards code relating to XML - things like the DOM,
SAX, and JAXP interfaces.

As the xml-commons community forms, we also hope to serve as a holding area
for other common xml-related utilities and code, and to help promulgate
common packaging, testing, documentation, and other guidelines across all
xml.apache.org subprojects.
