Subject: [PATCH 3/4] libvncserver/auth: don't keep security handlers from
previous runs
Whyohsoever security handlers are stored in a variable global to the
application, not in the rfbScreen struct. This meant that security
handlers registered once would stick around forever before this commit.

Subject: [PATCH 4/4] zlib: Clear buffer pointers on cleanup (#444)
The pointers to the buffers were freed, and the size fields were set to
0, but the buffer pointers themsef was not set to NULL, when shutting
down, meaning the next time used, NULL checks would not tell whether the
pointer is valid. This caused crashes ending with
