* generic/tclEvent.c: TclSetLibraryPath's use of caching the
stringrep of the pathPtr object to TclGetLibraryPath called from
another thread was ineffective if the original's stringrep had
been invalidated as what happens when it gets muted to a list.
* generic/tclInt.h:
* generic/tclThread.c:
* generic/tclEvent.c:
* unix/tclUnixThrd.c:
* win/tclWinThrd.c: Provisions made so masterLock, initLock,
allocLock and joinLock mutexes can be recovered during
Tcl_Finalize.
