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 redundant '-*' from CONFLICTS definitions

The conflict checks compare the patterns first against the package
names without version (as reported by "pkg query "%n"), then - if
there was no match - agsinst the full package names including the
version (as reported by "pkg query "%n-%v").

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.

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 v, w, x, y, and z.

x11-tools/gtkada3: Fix build when DOCS option is deselected

These appear on the GPS IDE menu and most users are only building gtkada3
to build GPS.  But it is an option and thus needs to be supported)

While here, strip two libraries.

Ada Framework: Switch to gcc5-aux, upgrade 6 packages at once

The transition from gcc-aux to gcc5-aux in the Ada framework has been
blocked by the inability to build gtkada3 and, once resolved, GPS (due
to tight locking with compiler).

A few days ago, Adacore made their annual release of their main libre
products, include GPS.  However, some products were tightly coupled with
the recent compilers, so in order to upgrade, the compiler had to be
switched and dependencies require many ports to be upgraded at once:

  * lang/asis
  * devel/gnatcoll
  * devel/gps
  * x11-toolkits/gtkada3

x11-toolkits/gtkada3: Update version 3.8.3.0 => 3.8.3.1

While working on the GPS port, GtkAda received a minor bug fix.  Just
bring this new version in before GPS 6.0.x.

The makefile was slightly modified to keep using the 3.8.3.0 version
of the reference manual.  Also the ability to build a debug version
was added as a non-default option.

toolkits/gtkada3: Update COMMENT, GTK3 instead of GTK2 is used

Add new Ada port: x11-toolkits/gtkada3

The GTK/Ada library is a key component of the GNAT Programming Studio.
The GPS 5.x series used GTK2 components through GKT/Ada.  For the new
6.x series of GPS, GTK3 components are needed and GTK/Ada has been
updated accordingly.

Since GTK/Ada is actually a generic component, it has been decided to
freeze x11-toolkits/gtkada at version 2.24 as this is the last version
that supports GTK2.  To support the upcoming GPS 6.0, this gtkada3 port
based on GTK3 is required.

This port naturally conflicts with x11-toolkits/gtkada.  Once GPS is
upgraded, the gtkada port may be reworked so it can co-exist with the
gtkada port.
