Title:
  Backport QQuickAsyncImageProvider from upstream-dev

Status in qtdeclarative-opensource-src package in Ubuntu:
  Fix Released
Status in thumbnailer package in Ubuntu:
  Invalid

Bug description:
  In Qt <= 5.5 there is exactly one thread that handles loading of
  images that come from custom image providers, this means that if a
  given image provider is very slow it will block the rest of image
  providers.

  Qt 5.6 introduces QQuickAsyncImageProvider that is a job based API
  that allows the custom image providers to run threads on their side,
  this way they won't block other requests.

  By backporting QQuickAsyncImageProvider we can solve
  https://bugs.launchpad.net/thumbnailer/+bug/1425043 by making the
  thumbnailer have a "slow" thread for thumbnails that it needs to do
  and a "fast" one for thumbnails that are already done as shown by the
  proof of concept implementation at
  https://code.launchpad.net/~aacid/thumbnailer/asyncprovider/+merge/253188
