Upgrade from circa 2000 to circa 2014 code. Unfortunately, upstream

are somewhat sloppy about releases -- and do not publish versioned
files. I'm calling this one 3.6.2, because that's the last version
found in the change log.

The new build uses bsd.lib.mk and bsd.prog.mk -- in order to:
	a) build shared libraries cleanly;
	b) stand a chance of working on the hardware platforms,
	   where the author never tried it.

The large patches provide for warning-free compiles with WARNS=7 --
tested on FreeBSD-11/amd64.

We now take care to link with libgnuregex.so -- whether from base
or provided by devel/libgnuregex instead of using the bundled
(ancient) version of Henry Spencer's library.

Similarly, the port links with the base -lmd instead of compiling
its own MD5-implementation.

Additional new feature is options, which currently include:

	. Socket support -- this used to be built unconditionally
	  and is still on by default. However, someone concerned
	  about the "network daemon" security warning may want to
	  to turn this off.
	. Regex module -- also on by default. But, because it may,
	  depending on the OS version, drag in a dependency, it
	  can be turned off.
	. NDBM -- a never-before built (not on FreeBSD) module
	  allowing work with NDBM databases. On by default now,
	  because it has no dependencies.
	. GD -- the graphics library. Never built before by this
	  port, it remains off by default because it depends on
	  graphics/gd (or ukrainian/gd).
	. SQL_SYBASE -- for interactions with Sybase (and MS-SQL)
	  database servers. Depends on databases/freetds and therefor
	  off by default.

There is also sql_oracle module, which is not enabled (for now),
because databases/oracle8-client is, unfortunately, i386-only.

The peculiarity of installing siod.html into ${PREFIX}/lib/siod
remains for now -- suggestions welcome.
