Add TSS error handling.
The TSS specification defines many return codes for the different components of
the TSS: TSP, TCS, TDDL, TPM. In order to adequately handle and log errors in
each subsystem, the following utility functions are needed:
- Appropriate bits set in the return codes to identify which subsystem
generated the error.
- Conversion from numeric return codes to human-readable messages for logging
purposes.
Some additional macros have been added to the TSS header files that were
present in the specification, but not the header files.
