rsyslog work log 8

Past day's rsyslog work log: 2008-05-06 - added documentation for TLS - merge TLS branch into main devel branch - released 3.19.0 (MILESTONE, we now have TLS! :-D ) - some cleanup (gotten rid of some more plain chars) - fixed some issues thanks to darix - fixed problem with man pages thanks to Michael Biebl's help 2008-05-07 - fixed some issues in liblogging (thanks to darix for pointing out) - limited number of unavoidable compiler warnings when compiling with GnuTLS - released 3.19.1 2008-05-08 - bugfix: gtls netstram driver did not specify threading model (can possbly lead to "interesting effects" ;)) - server's X509 cert fingerprint is obtained by client on connect - thought hard about syslog-transport-tls-12 (obviously, this does not manifest in code ;))
