Log Message:
Update to 2.5.0; upstream changes:

 * Do not attempt to reload SM modules on SIGHUP
 * Cleanup config files example
 * Fixed memory leak in pgsql storage driver
 * Fixed two double-frees caused by dangling pointers
 * Fixed c2s logger initialization point

On NetBSD, sm receives a SIGHUP shortly after being started from rc.d,
which causes a crash.  With 2.5.0, sm starts correctly on boot.
