This patch provides support for 'joining a thread' by wrapping pthread_join with qemu_thread_join. Since the backend implementation is based on threads and I am stopping and starting that thread during operations like 'snapshot resume', I do use this functionality to synchronize with the TPM thread's termination before terminating the TPM, creating a new one and loading previous state from the time of the snapshot into the TPM.
