* win32-low.c (do_initial_child_stuff): Add process handle
parameter. Set current_process_handle and current_process_id from the
parameters. Clear globals.
(win32_create_inferior): Don't set current_process_handle and
current_process_id here. Instead pass them on the call to
do_initial_child_stuff.
(win32_attach): Likewise.
(win32_clear_inferiors): New.
(win32_kill): Don't close the current process handle or the
current thread handle here. Instead call win32_clear_inferiors.
(win32_detach): Don't open a new handle to the process. Call
win32_clear_inferiors.
(win32_join): Don't rely on current_process_handle; open a new
handle using the process id.
(win32_wait): Call win32_clear_inferiors when the inferior process
has exited.
