* New upstream release 0.20.0 (https://launchpad.net/mir/+milestone/0.20.0)
  - ABI summary: Only servers need rebuilding;
    . mirclient ABI unchanged at 9
    . mirserver ABI bumped to 38
    . mircommon ABI unchanged at 5
    . mirplatform ABI unchanged at 11
    . mirprotobuf ABI unchanged at 3

    . Separate the protocol version number from the client API version macros.
      They're not meant to be related concepts.
    . Add UBSanitizer to the list of build types.
    . logging: Human readable timestamps in DumbConsoleLogger.
    . examples: AdorningDisplayBufferCompositor::composite() no long ignores
      output boundaries and occlusions.
    . examples: Add -a <app name> option to eglapps.
    . common, client: a more flexible way to probe modules: once we've found
      a good current platform we don't even try to load an older one.
    . Fix build and test run with CMAKE_BUILD_TYPE=ThreadSanitizer (missing
      locks).
    . Add MIR_USE_LD_GOLD build option.
  - Bug fixes:

      case they are unplugged (LP #1531503). [Cherrypicked from 0.21]

Only do double buffering on the compositing screencast which is enough.

Fix screen implementation to work properly with multiple buffers.

Disable compositing screencast unit tests

1261. By Simon Fels on 2016-02-12

Extend compositing screencast to work with a list of three buffers to
give our users a bit more control over when things should be rendered
and processed. If we're limiting us to only one buffer the user needs
to process and we can't prepare the next one already in the same time.
