The requested feedback was to convert the tpmdev handler to being json
based, which requires rethreading all the backends. The good news is
this reduced quite a bit of code (especially as I converted it to
error_fatal handling as well, which removes the return status
threading).
v3 pulls out more unneeded code in the visitor conversion, makes
migration work on external state preservation of the simulator and
adds documentation
v4 puts back the wrapper options (but doesn't add any for mssim since
it post dates the necessity)
v5 rebases to the latest master branch and adjusts for removed use_FOO ptrs
v5 updates help to exit zero; does some checkpatch tidying
v7 merge review feedback and add acks.
v8 adds better error handling, more code tidies and adds command
socket disconnection/reconnection (instead of trying to keep the
socket open the whole time). This adds overhead, but makes
debugging guest kernel TPM issues much easier.
v9 Fix merge conflict with optarg->optstr conversion
v10 Fix more merge conflicts and update API versions
v11 Fix another merge conflict and correct a warm reboot problem where
the TPM isn't getting reset (meaning the PCR values are wrong).
