When testing downgrading from libtpms 0.8 to 0.7 (which is not
possible), the error message which is reported is:
libtpms/tpm2: Unexpect value for MAX_RSA_KEY_BITS; its value 3072 is
not = 2048; (version: 2).
codespell (https://github.com/codespell-project/codespell) reports a
misspelling for "Unexpect", which should be "Unexpected". As the project
contains many more misspellings in comments, error messages and
documentation, fix all misspellings reported by codespell.

Introduce --with-tpm2 for ./configure to enable building with
TPM 2 functionality. Delay the building of TPM 2 code until more
patches are applied and the vTPM state that's created has a chance
of being backwards compatible.
Extend the libtpms API to allow user to choose version of TPM.
Missing functionality at this point:
- TPM 2 needs to be extended to serialize and deserialize its volatile state
- Handling of the establishment bit

This is the initial import of the libtpms library. The libtpms library
provides software emulation of a Trusted Platform Module (TPM). It is
intended to be used by applications when a hardware TPM is not adequate.
For example, a hypervisor can use libtpms to emulate an independent TPM
for each of it's virtual machine guests. The library provides a high-
level API for developers to integrate the emulated TPM support into
their application.
