* Actually start a process. All of the arguments given to this

* limitation that it does NOT allow passing command line arguments
* with spaces to the new process.
*
+ * @param pipe_control should a pipe be used to send signals to the child?
+ * @param std_inheritance a set of GNUNET_OS_INHERIT_STD_* flags
* @param lsocks array of listen sockets to dup starting at fd3 (systemd-style), or NULL
* @param first_arg first argument for argv (may be an empty string)
* @param ... more arguments, NULL terminated
- * @return PID of the started process, -1 on error
+ * @return handle of the started process, NULL on error
