[libvirt] [PATCH 3/3] ui: remove support for SDL1.2 in favour of SDL2

SDL1.2 was deprecated in the 2.12.0 release with: commit e52c6ba34149b4f39c3fd60e59ee32b809db2bfa Author: Daniel P. Berrange <berrange(a)redhat.com&gt; Date: Mon Jan 15 14:25:33 2018 +0000 ui: deprecate use of SDL 1.2 in favour of 2.0 series The SDL 2.0 release was made in Aug, 2013: https://www.libsdl.org/release/ That will soon be 4 + 1/2 years ago, which is enough time to consider the 2.0 series widely supported. Thus we deprecate the SDL 1.2 support, which will allow us to delete it in the last release of 2018. By this time, SDL 2.0 will be more than 5 years old. Signed-off-by: Daniel P. Berrange <berrange(a)redhat.com&gt; Reviewed-by: Marc-André Lureau <marcandre.lureau(a)redhat.com&gt; Message-id: 20180115142533.24585-1-berrange(a)redhat.com Signed-off-by: Gerd Hoffmann <kraxel(a)redhat.com&gt; It is thus able to be removed in the 3.1.0 release.
