+ Reworked management of the "errorInfo" data of an interp.
+ That information is now primarily stored in a new private
+ (Tcl_Obj *) field of the Interp struct, rather than using a
+ global variable ::errorInfo as the primary storage. The
+ ERR_IN_PROGRESS flag bit value is no longer required to manage
+ the value in its new location, and is removed. Variable traces
+ are established to support compatibility for any code expecting
+ the ::errorInfo variable to hold the information.
+
+ ***POTENTIAL INCOMPATIBILITY***
+ Code that sets traces on the ::errorInfo variable may notice a
+ difference in timing of the firing of those traces. Code that
+ uses the value ERR_IN_PROGRESS.
