monitor: Don't change VNC server when disabled (Jan Kiszka)

[ As requested, broken out of the monitor rework series. ]

Avoid a segfault when the user issues 'change vnc' without having vnc
enabled on startup.

Add zlib encoding support (Alexander Graf)

This patch adds zlib encoding support for VNC. It basically runs
the raw traffic through zlib, providing a pretty good compression
ratio.

Move the framebuffer update package out (Alexander Graf)

Currently the send_framebuffer_update_raw and send_framebuffer_update_hextile

Use VNC protocol defines (Alexander Graf)

Now that we have nice defines for all sorts of constants, let's
use them!

This patch also takes the "feature variables", currently called has_*
into a single feature int. This way adding new features is a lot
easier and doesn't clutter the VncState struct....

Split VNC defines to vnc.h (Alexander Graf)

The VNC protocol contains quite some constants, some of which are
currently hardcoded in the vnc.c code. This is not exactly pretty.

Let's move all those constants out to vnc.h, so they are clearly
separated. While at it, I also included other defines that will be...
