Added an ability to virtualize TPM commands into an isolated context that we call a TPM space because the word context is already heavily used in the TPM specification. Both the handle areas and bodies (where necessary) are virtualized. The mechanism works by adding a new parameter struct tpm_space to the tpm_transmit() function. This new structure contains the list of virtual handles and a buffer of page size (currently) for backing storage. When tpm_transmit() is called with a struct tpm_space instance it will execute the following sequence: 1. Take locks. 2. Load transient objects from the backing storage by using ContextLoad and map virtual handles to physical handles. 3. Perform the transaction. 4. Save transient objects to backing storage by using ContextSave and map resulting physical handle to virtual handle if there is such. This commit does not implement virtualization support for hmac and policy sessions.
