some more "ignore-glob" patterns
3610026 Stop segfault when regexp overflows color limits.
Demand the error message indicating the purpose of the test.
3610026 Stop crash when the number of "colors" in a regular expression
overflows a short int.  Thanks to Heikki Linnakangas for the report and
the patch.
Make (deprecated) Tcl_EvalObj/Tcl_GlobalEvalObj macro's always, not only when using stubs.
Allow URLs that don't have a path, but a query, e.g. http://example.com?foo=bar and bump http to 2.5.8.
Implement Tcl_Pkg* functions as macro's around Tcl_Pkg*Ex. This saves stack space, is (marginally) faster, while still being fully up/down compatible. It makes pkgb.so loadable in "novem" without the need to change the Tcl_PkgProvide() call to Tcl_PkgProvideEx().
Merge 8.4; Tag for release.
