LibVNC commit before d01e1bb4246323ba6fcee3b82ef1faa9b1dac82a contains a
memory leak (CWE-655) in VNC server code, which allow an attacker to
read stack memory and can be abused for information disclosure. Combined
with another vulnerability, it can be used to leak stack memory and
bypass ASLR. This attack appear to be exploitable via network
connectivity. These vulnerabilities have been fixed in commit
d01e1bb4246323ba6fcee3b82ef1faa9b1dac82a

We want to use SPDX identifier for license strings as much as possible.
SPDX short identifier for GPLv2/GPLv2+ is GPL-2.0/GPL-2.0+.
This change is done by using following command.

TightPNG encoding speeds up HTML5 based VNC clients like noVNC.
libvncserver enables this encoding if both libpng and jpeg libraries
are available.

The libvncclient library (part of libvncserver) has optional support
for HW accelerated H264 video playback using libva
However there are currently two problems with it:
1) it only supports libva compiled with X11 support enabled, but it
does not verify that is the case, resulting in compile errors.
2) it only supports the libva 1.0.x API, and not newer
libva versions, like 1.4.x we include with buildroot.
https://github.com/LibVNC/libvncserver/issues/11
Disabling libva support for now.
