Danylo Piliaiev requested to merge Danil/vkpipeline-db:fix/pipeline-state-crash into master Mar 15, 2019

Vulkan spec permits next states to be NULL in certain cases:

pTessellationState
pViewportState
pMultisampleState
pDepthStencilState
pColorBlendState
pDynamicState

The lack of checks caused crashes during capturing pipelines of The Witness and The Witcher 3.

It is backward incompatible change since I added field to binary format.
