[PATCH v5 0/2] tpm: add mssim backend

[James Bottomley <jejb@linux.ibm.com>]

From: James Bottomley <James.Bottomley@HansenPartnership.com>

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).  The bad news is I can't test any of the conversions.
swtpm still isn't building on opensuse and, apparently, passthrough
doesn't like my native TPM because it doesn't allow cancellation.

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
