Fix warnings in whiptcl.c and include Tcl_PkgProvide() call
Fix warnings in whiptcl.c and include Tcl_PkgProvide() call

whiptcl.c needs a lot of patching to build with modern Tcl (such as 8.4
or 8.5).

The module also forgets to provide a package and so loading via the
"package require" mechanism is impossible.
