      Fix a race condition with glib (Bug#8855). · 6d4e8f62

      This is a backport from the trunk, consisting of:
      2012-11-17  Eli Zaretskii  <eliz@gnu.org>
      * nt/inc/sys/wait.h: New file, with prototype of waitpid and
      definitions of macros it needs.
      * nt/inc/ms-w32.h (wait): Don't define, 'wait' is not used anymore.
      (sys_wait): Remove prototype.
      * nt/config.nt (HAVE_SYS_WAIT_H): Define to 1.
      * src/w32proc.c (create_child): Don't clip the PID of the child
      process to fit into an Emacs integer, as this is no longer a
      (waitpid): Rename from sys_wait.  Emulate a Posix 'waitpid' by
      reaping only the process specified by PID argument, if that is
      positive.  Use PID instead of dead_child to know which process to
      reap.  Wait for the child to die only if WNOHANG is not in
      (sys_select): Don't set dead_child.
      * src/sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
      as it is no longer needed.
      * src/process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
      no longer needed.
      (record_child_status_change): Remove the setting of
      record_at_most_one_child for the !WNOHANG case.

      Fix a race condition that causes Emacs to mess up glib (Bug#8855).
      This is a backport from the trunk.
      The symptom is a diagnostic "GLib-WARNING **: In call to
      g_spawn_sync(), exit status of a child process was requested but
      SIGCHLD action was set to SIG_IGN and ECHILD was received by
      waitpid(), so exit status can't be returned."  The diagnostic
      is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
      The real bug is a race condition between Emacs and glib: Emacs
      does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
      so that glib can't find it.  Work around the bug by invoking
      waitpid only on subprocesses that Emacs itself creates.
      * src/process.c (create_process, record_child_status_change):
      Don't use special value -1 in pid field, as the caller now must
      know the pid rather than having the callee infer it.  The
      inference was sometimes incorrect anyway, due to another race.
      (create_process): Set new 'alive' member if child is created.
      (process_status_retrieved): New function.
      (record_child_status_change): Use it.
      Accept negative 1st argument, which means to wait for the
      processes that Emacs already knows about.  Move special-case code
      for DOS_NT (which lacks WNOHANG) here, from caller.  Keep track of
      processes that have already been waited for, by testing and
      clearing new 'alive' member.
      (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
      now does this internally.
      (handle_child_signal): Let record_child_status_change do all
      the work, since we do not want to reap all exited child processes,
      only the child processes that Emacs itself created.
      * src/process.h (Lisp_Process): New boolean member 'alive'.
