x11/cde*: Remove llvm16 dependency

llvm16 is no longer needed to build the x11/cde ports. However this now
exposes a dependency on databases/lmdb.

x11/cde*: Catch up to src bb421be6c117

src bb421be6c117 moved ftime(3) to libutil. This resulted in this
error:

ld: error: undefined symbol: ftime
>>> referenced by getdate.c
>>>               libDtCmP_a-getdate.o:(cm_getdate) in archive
../libDtCmP/libDtCmP.a

There are other programs and libraries that also reference ftime(3).
Rather than patch each Makefile.am, add -lutil to LDFLAGS.

x11/cde*: Add a note about $PATH

CDE is installed in ${PREFIX}/dt, as it was installed in /usr/dt on
platforms like Solaris and Tru64.

x11/cde*: Work around a SIGBUS in dtcreate

dtcreate has been experiencing SIGBUS since llvm 17 import. Fall back
to llvm 16 until this problem can be more thoroughly investigated.

x11/cde*: Add missing shebang script

During 2023Q3 testing (using pudriere bulk -t, which enables
DEVELOPER mode), it was discovered that a tcl script was not getting
fixed by shabangfix. This commit fixes that.

x11/cde*: Remove call to tzsetall()

As of src d5c85ac6526d, the tzcode update removed the tzsetwall()
function. Our tzcode upstream removed tzsetwall() in their commit
d36f8f5b6983. The reason they did this was that tzsetwall() was
"undocumented and ineffective."

x11/cde-*: Depend on the more modern shells/ksh

Upstream already uses and depends on ksh93/ksh. Depend on it instead of the
older ast/ksh.

x11/cde-25: Update to 2.5.1

2.5.1 minor but what our upstream consider significant enough to roll
a new release including:

- load appropriate xterm font
- update ksh93 used as a basis to implement dtksh to 1.0.3

Though dtksh is based on ksh, it implements an API that allows ksh shell
scripts access to CDE functions.

x11/cde-{25,devel}: Remove BROKEN for imake build issues

As of 2.5.0 (from HISTORY in the tarball),

This release is the first to use autotools for building.  The Imake
build system is gone.  No doubt there is more improvement that can be
done here (support cross compiling, make uninstall, etc), but
everything is functional.

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.

x11/cde-25: Allow cde port/pkg coexistence

Allow cde-25 to coexist with other versions of CDE installed on the
same system.  This allows users to migrate or quickly revert back
should a user wish to temporarily do so. The reason for this is that
CDE 2.5.0 will use fonts such as gb2312.1980 which can mess up fonts
displayed by legacy Xm nd Xaw apps.

In such a scenaroio the user would define CDE_CONCURRENT in their
make.conf or poudriere.d/make.conf, then build and install the port.
When CDE_CONCURRENT is defined, the port is be installed in
${PREFIX}/dt25. To switch between the two CDEs a user could either
manually create a symlink as /usr/local/dt and possibly switch their
~/.dt from one environment or the other. Or one could use something
similar to the following in their .xsession or .xstart file:

x11/cde-25: Introduce the new x11/cde-25

CDE 2.5.0 has many improvements however some users may discover that
fonts used by legacy Xm and Xaw apps are unreadable due to legacy apps
using the gb2312.1980 font registry. For now cde-24 will remain the
default cde however users can install cde-25 for new features and
bugfixes.
