If ctx is null, it allocates and returns a new object, otherwise
it returns ctx. It initialises all the members as follows:
flags = TS_VFY_ALL_IMPRINT & ~(.TS_VFY_TSA_NAME | .TS_VFY_SIGNATURE)
certs = null
store = null
policy = policy from the request or null if absent (in this case
TS_VFY_POLICY is cleared from flags as well)
md_alg = MD algorithm from request
imprint, imprint_len = imprint from request
data = null
nonce, nonce_len = nonce from the request or null if absent (in this case
TS_VFY_NONCE is cleared from flags as well)
tsa_name = null
Important: after calling this method TS_VFY_SIGNATURE should be added!
