* dcrt0.cc (_dll_crt0): Accommodate breaking apart of early_stuff_init. 

* exceptions.cc (early_stuff_init): Delete.
(init_console_handler): New function - top half of early_stuff_init.
(init_global_security): New function - bottom half of early_stuff_init.
(sig_handle): Avoid special hExeced test for SIGINT.  Just terminate the
captive process.
(signal_exit): Add debugging output.
* fhandler_tty.cc (fhandler_tty_slave::open): Don't allocate a console if one
already seems to exist.  Properly initialize ctrl-c handling if we do allocate
a console.
* winsup.h (early_stuff_init): Delete declaration.
(init_console_handler): New declaration.
(init_global_security): New declaration.
