Backing out code that inserted a debug statement into the http package
The unix build has been pared down to the minimum hooks required to build a
VFS enabled Tclsh with a simple compile flag. Modified the BC and Visual Studio
makefiles for Windows, but these are untested.

The default for Tcl is now to build a static or dynamic shell in the same
way it would build a static or dynamic shell for Tclsh. Controlled by the
--enable-shared flag. Note however that ZLib is compiled in to every
VFS enabled shell. (Rather than rely on a dylib.)

The "direct" build is maintained in the Makefile, mostly as a h(istor|yster)ical
reference. The technique is not portable to Windows, and may not work outside of
OSX.
Modified the makefile to produce a distinct name for a kit depending on whether
it was compiled statically or dynamically.

This allows builders to run and install successive builds of Tcl both
statically and dynamically.
