Provide list of deployment artifacts

Hi,

This is a fix for Bug #9869 - Provide a per-target manifest of files which were, or would have been, produced

The list of artifacts produced by deployment tasks (do_deploy, do_image_complete and do_populate_sdk[_ext] is obtained from sstate manifests and fired as a TaskArtifacts metadata event. This should allow Toaster to handle artifacts in simple way and remove a lot of current Toaster code doing guess work.

To generate manifests for do_image_complete and do_populate_sdk they have been put under sstate control.

To avoid storing big files(images and sdk installer) in sstate new variable SSTATE_SKIP_CREATION has been set in image.bbclass and populate_sdk_base.bbclass and sstate code was modified to avoid adding files to sstate if SSTATE_SKIP_CREATION is set.

Changes in v2: Reorganized patchset to make it bisectable (Thanks Richard)
Used task in the name of DEPLOYDIR to avoid using the same directory for different tasks of the same recipe

Changes in v3: Fixed bug that caused deletion of image manifest

The following changes since commit 087c580b286816265f487e02746bfa6e26081554:
