To avoid having to specify applications more than once.

Possibly overkill for two modules but it mirrors their different
treatment by the makefile.

Albeit as comments. This is just to make it more obvious that these
aren't include in the modules list, since they typically aren't
needed/wanted on a target system. Also add comments for the
corresponding dependencies on syntax_tools and runtime_tools, as well as
the optional runtime dependency on ssl.

Creating examples/code and examples/dict in parallel can fail when
examples doesn't exists. This has been seen on FreeBSD.

Add a 'strict' target to compile with -Werror and fix a dependency.
Reorder test suites alphabetically. The two suites that currently take
the longest to run conveniently come last.

The RFC 6733 accounting dictionary includes rfc6733 in its name. The RFC
3588 dictionary doesn't and is left as-is for backwards compatibility.

For building unofficial patches.
