Bug Description

a commit needs to be backported to bionic so that a test passes

[Test case]
check that the test passes

[Regression potential]
low, the commit has been upstream for some time now


Currently Bionic contains 1.0.0-2ubuntu2 version of libegl1.

There is a bug in due to which a Khronos CTS failure happens on ARM platform.

Cosmic has already upgraded to 1.0.0+git20180308-3ubuntu1 version of libegl1 where this bug is fixed.

Details of fix in liglvnd-EGL code:
Failing Khronos CTS test: dEQP-EGL.functional.negative_api.make_current, which runs in bot OpenGL and OpenGL-ES CTS runs.

Without above test passing, we can't submit logs to Khronos for the CTS run.

Filing this bug to get libegl1 upgraded to cosmic's version in bionic repos.
We've verified locally on ARM platform, there are no issues present due to this upgrade.

Verified that earlier broken Khronos CTS test dEQP-EGL.functional.negative_api.make_current Passes with this update.

To upgrade libglvnd0, I did following:
1) Add "deb bionic-proposed restricted main multiverse universe" in /etc/apt/sources.list
2) sudo apt-get update
3) sudo apt-get install --only-upgrade libglvnd0
