krfb/libvncserver/stats.c
George Kiagiadakis 9f56633c0b Sync with libvncserver from git (git describe version: 0.9.8-10-g17ce0c5). 
My patches in this local fork have been merged upstream, but they
have been merged after 0.9.8 and 0.9.9 hasn't been released yet,
so we cannot yet switch back to finding libvncserver externally.

So I am syncing now with basically what is 0.9.8 + my patches and a few bugfixes.
