Anton Blanchard bdeb4bab50 Restore terminal if exit is called inside a TCL script at startup ...

If exit is called in a TCL script that is executed at startup, the libc
exit() function is called directly and we don't get a chance to reset
the terminal. We return to the shell with echo off, and have to run
"reset". A simple example:

echo exit > test.tcl
magic -noconsole -dnull  test.tcl

There are a few ways we could solve this. We could register an exit
handler using atexit(). Here I use Tcl_SetExitProc() to register a
callback with the TCL interpreter.
