Summary: missing ThreadKill() on unix

Initial Comment:

After restoring ability to build and install Thread
(see Bug 487213), I try a test:

$ make test
/usr/local/lib/../bin/tclsh8.3 ./tests/thread.test
couldn't load file
"/usr/local/lib/thread2.3/../libthread2.3.so":
/usr/local/lib/thread2.3/../libthread2.3.so: undefined
symbol: ThreadKill
    while executing
"load /usr/local/lib/thread2.3/../libthread2.3.so"
    ("package ifneeded" script)
    invoked from within
"package require Thread 2.0"
    (file "./tests/thread.test" line 18)
make: *** [test] Error 1

Sure enough, ThreadKillObjCmd() in generic/threadCmd.c
calls ThreadKill() that is only implemented in
win/threadWin.c.  The unix implementation is missing.

ThreadKill() can't work on windows anyways.  Tcl_ThreadCreate doesn't save the new thread's handle.  Without it, we can't TerminateThread() with it.  Some people made strong requests for a way to kill a thread and there it is.  As far as can be done showing the limits of Tcl's API waiting for someone else to come along and finish it.

suggest:  Se how the core save's handles associated to process IDs with the [pid] command.  Copy the idea for threads to allow the ability to get a handle from a global thread ID.
