get fix for test error under -DPURIFY
merge trunk: get fix for test error under -DPURIFY
suggested fix for Bug 3092089: [file normalize] can remove path component,

merge trunk

 ... tmp
reenable compiled tailcall
more abstraction
move TCL_EVAL_REDIRECT from iPtr->evalFlags (tclInt.h) to flags passed to the eval functions (tcl.h)
backout, and merge trunk
