stunnel: Update to 5.36, use pthreads and SSP.

Updates stunnel to 5.36, changes it from using forking to pthreads and
enables SSP linking. Also changes maintainer to myself.

Regarding pthreads vs forking, http://blog.haproxy.com/2011/09/16/benchmarking_ssl_performance/
SSP is short for Stack Smashing Protector and you can read about it here: http://wiki.osdev.org/Stack_Smashing_Protector
