Implementation files for command marshaling.
Generated C source and header files which add functions to unmarshal command
requests, execute commands, and marshal command responses. This
(tenatively) adds all final missing parts of libtpm2. These files are
generated from command_generator.py in CL:290556.
TEST=$ sudo emerge tpm2
builds libtpm2.a
Locally I was able to call ExecCommand to execute TPM2_Startup with
success after software TPM initialization.
