#574: More exessive memory usage

---------------------+------------------------
It appears that there are still cases in which Bro uses excessive amounts
of memory and doesn't release them when using the SSL-anlyzer (which is
enabled by default). I couldn't pinpoint the exact reason, but it looks
very similar to
#565.
My guess is that for some there is some dynamic length field so something
in the SSL-analyzer that allocates large amounts of buffer space and which
is particularly "expensive" for long-lived connections.
The memory usage doesn't suddenly jump. Memory usage grows in small
increments over longer periods of time (e.g., 500MB--2GB in 30--60min) and
then stays high.
(In addition I also noticed that Bro's memory footprint with SSL analyzer
is 10%--20% higher pretty soon after startup)
