Jeffrey Altman 237cd892d9 kdc: unused pid element is (pid_t)-1 not zero ...

When the termination of a child process is observed by reap_kid() it
clears the pids[] element by assigning it the invalid pid value
(pid_t)-1. However, start_kdc() assumes that the unused pid[[] element
value is 0.  As a result, each pid[] element's associated child process
can only be restarted once since start_kdc() will not be able to locate
an unused element.

This change alters start_kdc() to initialize all elements of pids[] to
(pid_t)-1 and use that as the marker for unused elements.  By doing so
start_kdc() can properly record child process pids and indefinitely
restart child processes as necessary.
