Don't unblock SIGCHLD too early.
We first need to register the received process ID so that
'handle_child_signal' checks it. Otherwise we might never call
'waitpid' for these processes, risking deadlock.
* src/callproc.c (call_process):
* src/process.c (create_process): Don't unblock SIGCHLD before
registering the process ID to wait for.
* src/callproc.c (emacs_spawn): Accept a signal set from the caller.
