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

Disable libvncserver for static builds and drop second patch following
upstream feedback on patch fixing openssl issue:
https://github.com/LibVNC/libvncserver/pull/319
This will also fix build failure when building statically with libgcrypt
Don't update x11vnc, the reverse dependency of libvncserver, because
BR2_PACKAGE_XORG7 already depends on !BR2_STATIC_LIBS

Fixes CVE-2018-7225 - An issue was discovered in LibVNCServer through
0.9.11. rfbProcessClientNormalMessage() in rfbserver.c does not sanitize
msg.cct.length, leading to access to uninitialized and potentially sensitive
data or possibly unspecified other impact (e.g., an integer overflow) via
specially crafted VNC packets.

Since SourceForge sometimes serves us faulty tarballs, we can tons of
autobuild failures:
http://autobuild.buildroot.org/results/9fb/9fba5bf086a4e7a29e5f7156ec43847db7aacfc4/http://autobuild.buildroot.org/results/6c8/6c837b244c45ac3b3a887734a371cd6d226cf216/
...
Fix that by adding hash files for all SourceForge-hosted packages (thos
etht did not already have it).
We normally prefer to use hashes published by upstream, but hunting them
all one by one is a tedious task, so those hashes were all locally
computed with a script that searched for SF-hosted packages, downloades
the associated tarball, computed the hash, and stored it in the
corresponding .hash file.
Also, SF publishes sha1 hashes, while I used the stronger sha256, since
sha1 is now considered to be relatively weak.

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.
