  Changed paths:
    M lib/daemon-unix.c

  Log Message:
  -----------
  daemon-unix: Use same name for original or restarted children.

Linux has an idea of process name that is visible in /proc/$pid/comm.  This
is "ovs-vswitchd" for a freshly started ovs-vswitchd process.  When the
monitor code restarted a crash child, it changed it to the empty string.
This confused the daemon_is_running check in ovs-lib.in, which checks
comm.  This commit fixes the problem by setting the program name as comm
in newly restarted children.
