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.
