* qemu_add_child_watch: Register a child process for reaping.

* Under POSIX systems, a parent process must read the exit status of
* its child processes using waitpid, or the operating system will not
* free some of the resources attached to that process.
*
* This function directs the QEMU main loop to observe a child process
* and call waitpid as soon as it exits; the watch is then removed
* automatically. It is useful whenever QEMU forks a child process
* but will find out about its termination by other means such as a
* "broken pipe".
