tpm2-protocol 0.10.0 / tpm2sh 0.10.0

tpm2-protocol and tpm2sh has been split:

- tpm2-protocol is spec complete since the last release, and this the first release of gradual improvements. I've contacted TPM-RS project and going to participate to their meeting on next Monday. The idea I'm selling here is to have a shared project for protocol, which tracks the specification, and associated project can then import the source code aligned with their own release cycle.

- tpm2sh is my kernel hacking tool that will gain features and improvements with no strings attached to anything. I said to Joe Richey (Google) that taking, relicensing and further contributing some of its more interesting features from its GPL3 code base is not out of question (protocol is Apache/MIT). One feature in particular under discussion is pretty printer, which probably would make sense also for kernel.

"Where's ******* driver!?" you may ask.

Well, I think this needs to be approached like I do in order to get some day driver that can do more than the pre-existing C driver, and not just implement a random Rust driver.

This was also my main concern with kernel's Rust code i.e., that any possible driver would be implemented from infeasible starting position.
