Add new ioctls to get and set the 3 different types of state blobs
from and to the CUSE TPM. Add test cases for testing the new ioctl's
on a CUSE TPM that stores the state encrypted and on a CUSE TPM that
stores it non-encrypted.

Create uniqe names for the /dev/vtpm* so that tests can run in parallel.
Also separate the state directories of the TPMs into individual temporary
dirs.
