They are new modules and not generated files.

It creates an invalid region if given an empty rect. Fortunately
RegionInitBoxes() handles that just fine, so use that instead.

We no longer support such old X servers so start using the current
functions.

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.

Otherwise it might fail if the repositories have changed since the image
was generated.

We now require at least 1.16, so remove all code that handled older
versions than that.

We removed support in the code ages ago, but overlooked this part of the
documentation. Also remove some dead code in Xvnc on the same theme.

Most window managers won't like this, and it tends to provoke bugs in
FLTK, so let's avoid it. It's probably not what the user wants anyway.

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.

The previous error messages did not support Unicode characters. This
commit will use UTF-8 encoding to be able to display error messages in
every language.

No current distribution ship anything this ancient anyway.

This makes our builds directly compatible with most distributions
without packagers/users having to specify extra flags.

Running as a service on a SELinux system requires rules so we can
transition to our own context. We also need the proper permissions
to start new user sessions.

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
displays is now done via a configuration file.

It is present on all UNIX systems anyway, so let's simplify things.
We will need it for more proper session startup anyway.

Assume we are part of a complete and proper installation and encode the
full expected path in to the vncserver script.

It keeps much better track of the X server and startup files than
we can do.

We need to be started as a system service for things to work correctly
anyway, so delegate the work of starting and stopping things to the
system service manager (e.g. systemd).

This is how display managers (e.g. gdm or lightdm) start sessions
and is necessary to get the proper set of environment variables.

We don't want to create files in the users home directory unless we
have to. Users can read about how this file works in our man pages.

We now have config files for more fine grained control of these
things, so avoid duplicating the functionality.

These might contain values we want if we are start from a proper
environment.

It is the most common init system these days so it should not be
hidden in the contrib/ directory.

This also removes all old SysV files from the contrib packages.

Install some example files to make things more easily discoverable.

These are EOL (or soon to be) and we want to start relying on things
present in current distributions.

There are multiple "okay" return values, not just Z_OK. Make sure we
don't bail out needlessly.

We adapted to the wrong new callback in a previous commit.

The CConnection base class wants to be able to write things these days,
so we need to provide it a place to do so.

Read username and passwrod from env.

This allows Xvnc to build with xorg-server 1.20.7, which requires OS
layers to implement a ddxInputThreadInit function when configured with
--enable-input-thread (the default).

relevant xorg-server commit: e3f26605d8

As gettext needs some stuff from Carbon and we don't want to rely on it
being pulled in as a side effect.

Modern MinGW seems to provide this, so simplify things a bit. This also
side steps some of the issue of the windows.h/winsock2.h include
ordering.

Not every mouse has three buttons e.g. laptops. Some OS might not
have support for middle mouse button emulation.

This commit adds emulation for middle mouse button when pressing both
left and right mouse button simultaneously.

This was not necessary since you could use ESC key or simply just
clicking outside of the context menu to close the menu.

Otherwise such clients cannot use Scroll Lock at all, and that is
probably worse than any effects we might get from getting out of sync.
