This patch does the following:
- moves vm->task_info struct to fpriv->task_info.
- makes task_info allocation dynamic.
- adds reference counting support for task_info structure.
- adds some new helper functions to find and put task_info.
- adds respective supporting changes for existing get_task_info consumers.
