Support touch gestures on Windows
This adds the same touch gesture support for Windows as already added
for Unix. Note that it uses Windows gesture detection instead of our own
here though to give the user a familiar experience. Unfortunately that
means we lose the three finger tap.
This also raises the base requirements to Windows 7 as that's when
Windows got proper touch support.

Cancel AltGr timeout on mouse events as well
We have a timer after Ctrl is pressed in order to see if an Alt will
come right after. Ctrl + Alt is what windows sends for AltGr.
If a key other than Alt was pressed we knew that we could cancel this
timer, this commit extends that to mouse events too.
Since this detection breaks the true order of events we want to make
a decision as fast as possible.

Fix position for click and drag with EmulateMB
If you have the setting "Emulate middle mouse button" turned on, a click
and drag can fail if it is done very quickly. The position of the
initial click will be incorrect in such a case because the timeout will
delay events.

Open X11 display properly
We need to make sure everything happens in the correct order during
startup for the X11 display to open correctly. Primarily it means
we need to parse the arguments and open the display before anything
might make any X11 calls, as we may have a -display argument.

Handle empty changes for every operation
It seems like many of the X11 operations can end up with no pixels
actually changing. So instead of discovering and adding workarounds for
each individually we'll just check very region added if it's empty.

Throw GAIException() for getaddrinfo errors
Created a new subclass of Exception called GAIException() that will
handle error messages from getaddrinfo() instead of letting Exception()
handle it. GAIException() will make use of gai_strerror() to map the
error code to text. On Windows, gai_strerrorW() must be used if the text
is encoded with UTF-8.

Add SELinux policy file for vncsession
Running as a service on a SELinux system requires rules so we can

Start sessions via PAM
This sets up a more correct session as there are key tasks that
need to be performed by PAM. E.g. systemd will allocate cgroups
and start base services.
In order to easily handle this as a system service the mapping of
