* generic/tclAlloc.c:
* generic/tclInt.h:
* generic/tclThreadAlloc.c (new):
* unix/Makefile.in:
* unix/tclUnixThrd.c:
* win/Makefile.in:
* win/tclWinInt.h:
* win/tclWinThrd.c: added new threaded allocator contributed by
AOL that significantly reduces lock contention when multiple
threads are in use. Only Windows and Unix implementations are
ready, and the Windows one may need work. It is only used by
default on Unix for now, and requires that USE_THREAD_ALLOC be
defined (--enable-threads on Unix will define this).
