Module session 

For sessions, context managements works as follows:

1. TPM2_ContextSave transforms an active session into saved session, which gets a handle from the same address range as HMAC sessions.
2. TPM2_ContextLoad transforms a saved session into active session, and session regains the handle assigned upon creation.

Consequences:

1. TPM2_FlushContext must not be applied after TPM2_ContextSave.
2. TPM2_FlushContext can be only applied to a loaded session.
