[Bug 1687981] Re: Backport packages for 16.04.3 HWE stack

[Sandeep]

About Vulkan package:

Vulkan loader (libvulkan) has moved to newer version and that is needed
to make use of all the recently proposed vulkan extensions in the
application.

The main application that doesn't work currently is with Vulkan CTS:
https://github.com/KhronosGroup/VK-GL-CTS

Vulkan CTS passing is required for a device to be called as Vulkan
compatible.

We support only LTS releases on our devices so need latest version on
16.04. Can you please upgrade the libvulkan.so version to 1.0.42 for
Xenial?

This version is already available for latest ubuntu version (17.04).

Thanks.

Bug description:
  [Impact]

  *** hwe-16.04 refresh for 16.04.3 ***

  Revert changes to use debhelper10.

  xorg-server-hwe-16.04 needs updates
  - wayland 1.11 (but zesty has 1.12 which mesa needs so backport that)
  - x11proto-core 7.0.31
  - libxfont-dev 2.0.1, which also means backporting libxfont1 (NEW)

  x-x-i-libinput will not replace -evdev in x-x-i-all-hwe-16.04 because the unity mouse config doesn't work with -libinput.
  x-x-i-libinput needs newer libinput, which in turn needs libwacom update.

  Mesa needs llvm-4.0 and libclc, libdrm, wayland updates.

  [Test case]

  upgrade from/to stock & old hwe stack, test desktop usage

  [Regression potential]

  zesty hasn't blown up

  [Other information]

  build order:
  1. x11proto-core, libdrm, libxfont, libxfont1, libwacom, llvm-toolchain-4.0, vulkan, wayland
  2. libclc, libinput, xorg-server (build-dep libxfont1-dev)
  3. mesa, xorg-server-hwe-16.04
  4. drivers
  5. xorg-hwe-16.04
