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.

Update to version 0.6.1.

devel/alog: Update to 0.5.3

PR:		230724
Submitted by:	Nathan <ndowens@yahoo.com>

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

devel/alog; Upgrade version 0.5.1 => 0.5.2

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/alog: Upgrade version 0.5.0 => 0.5.1

devel/alog: not jobs safe

devel/alog: Remove reference to base/full flavors in pkg-descr

The "full" option was removed, along with pgsql, xmpp, and smtp
facilities, so this removes references that were in the description.

net/alog: Upgrade version 0.4.1 => 0.5.0

The upgrade removes:
  * The version package
  * The full option (pgsql, smtp, and xmpp facilities)

It switches to build with gprbuild
It fixes the policy database so that it's safe for concurrent access.

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

Add new Ada port: devel/alog

Alog is a stackable logging framework for Ada. It aims to be straight
forward to use and is easily extendable. It provides support for various
logger types, log facilities, loglevel policies and message
transformations.

The Alog library comes in two flavors: base and full. The base build
includes facilities to log to files and syslog while the full version
provides more advanced log facilities like SMTP, Jabber/XMPP or PostgreSQL.
The full version requires AWS (Ada Web Server) and APQ (Ada95 database
binding) and are offered as a non-default option.
