This was a proof of concept for an alternative WS interface -- write
incrementally to reserved workspace as an "open buffer".

That may be generally useful for Varnish, but for now we return to
the usual WS_* idiom.

The error may be status 500 on 32-bit systems.

On the various platforms, esp 32-bit, workspace may be exhausted
before it gets to the VMOD at all, so we can't reliably expect
specific error messages.

This has nevertheless improved GCOV coverage, which was the goal.

To get some better GCOV coverage. So far just IDENTITY encoding.

This reverts commit 0139f83c.

Despite its obsolete purpose in the previous life of the VMOD, we
include config.h in all C sources for consistent configuration.

Had been used in its previous life as a 3rd-party VMOD.
