This patch adds a signal handler for SIGTERM that will remove the
kdcinfo.REALM and kpasswd.REALM files before exiting. I had to move the
definition of krb5_ctx into krb5_common.h so I could dereference it to
get the realm name.
I also made the sig_term() function from server.c public, so I could
chain into it once my exit handler is done (to make sure it cleans up
any krb5_child processes that might still be in-progress).
