cleanup: Remove ports depending on expired lang/gcc6-aux

Keep ports-mgmt/synth and dependencies (including lang/gcc6-aux itself)
for now as synth is the only Ada port still maintained and might be
somewhat high-profile.

Removed ports:
archivers/zip-ada
cad/ghdl
databases/adabase
databases/apq
databases/apq-mysql
databases/apq-odbc
databases/apq-pgsql
devel/ada-util

Remove # $FreeBSD$ from Makefiles.

Bump PORTREVISIONs of all users of math/mpc that we just updated to
version 1.1.0 (via revision 464079).

Return ports maintained by John Marino to the pool, he is no longer interested.

Submitted by:	Mark Millard via private e-mail

Return the ports mistakenly reset to ports@ in r433856 to John Marino.

The mistake was completely on my part, I somehow connected the dots the
wrong way in my head.

The only exceptions (for now) are archivers/zstd and ports-mgmt/synth
which were already picked up by new volunteers in the mean time.

Return ports maintained by John Marino to the pool, see r433827 for details

Change Ada Framework foundation from gcc5-aux to gcc6-aux

GCC 6.1 was released this week.  The Ada Framework in FreeBSD ports has
been based on GCC 5.3 GNAT although GCC 6.x has been supported for awhile
via the ADA_DEFAULT option in make.conf.

Now that GCC 6 has been officially released, switch to it by default.
People can maintain the old foundation by putting "ADA_DEFAULT=5" in
/etc/make.conf.

Libraries built by one GNAT are unusable by another, so almost every Ada
port has been bumped as a result.  Noticable exceptions are dns/ironsides
which fails to build on gcc6 (thus USES=ada:5 is set) and cad/ghdl which
needs additional testing as it may require gcc5 on FreeBSD (DragonFly
uses the LLVM backend only).

Remove ${PORTSDIR}/ from dependencies, categories d, e, f, and g.

devel/adabooch: Upgrade version 20130322 => 20160321

- Switch to options helpers

Approved by:	portmgr blanket

MASTER_SITES cleanup.

- Replace ${MASTER_SITE_FOO} with FOO.
- Merge MASTER_SITE_SUBDIR into MASTER_SITES when possible. (This means 99.9%
  of the time.)
- Remove occurrences of MASTER_SITE_LOCAL when no subdirectory was present and
  no hint of what it should be was present.
- Fix some logic.
- And generally, make things more simple and easy to understand.

While there, add magic values to the FESTIVAL, GENTOO, GIMP, GNUPG, QT and
SAMBA macros.

Also, replace some EXTRACT_SUFX occurences with USES=tar:*.

marino 12 devel ports: Remove @dirrm, tend install commands, plus

The main purpose of this commit is to remove @dirrm from the pkg-plist of
some of my ports in devel category.  While here, also:
  * Unmask some commands
  * Use parenthesis on compound commands for multi-job support
  * Add a license in one case
  * USES=python conversion in one case
  * Add WWW and reformat description in one case
  * Respect 80-columns

devel/adabooch: Fix plist (orphaned file)

devel/adabooch: Rework installation target

For some reason, $prefix was already defined on DragonFly but
I didn't realize this was the reason it wouldn't install there until
after completely revamping the installation target.  In any case,
it's much better now.  No bump as there are no difference for FreeBSD
and it never built on DragonFly.

devel/adabooch: Update from version 20030309 to 20130322

This update has a documentation option, so the adabooch-doc-html
port is obsolete and will be removed shortly.  This 10-year newer
version is properly maintained and integrated into the Ada Framework.

devel/adabooch*: Take over maintainership of Adabooch ports

sylvio@ has been MIA for more than a year.  The Adabooch ports need
maintenance.  The doc port will be merged into main port upon upgrade.

New port: adabooch is a Booch implementation for Ada95

        The Ada 95 version of the components will contain the same
        key abstractions as the C++ form (Structs, Tools and Support).
        However, the organization will be slightly different,
        particularly in the Support domain. This is because Ada 95
        provides several special forms of memory management that
        are quite different from C++.

        The Structs category provides an array of structural
        abstractions (Bags, Collections, Deques, Graphs, Lists,
        Maps, Queues, Rings, Sets, Stacks, and Trees). The Tools
        category provides algorithmic abstractions (Searching,
        Sorting, etc.). The Support category contains all the
        "concrete" forms, plus structures to create the components.
