* Do not set userWithAuth by default when creating sealed objects. That flag allows password auth for the sealed object. Without the flag it only allows policy auth.
* Allow setting policy auth with flags.
* Fix secret_unseal to use policy session and valid sealed name.
* Added expected failure test cases for seal/unseal with policy.
* Improve the run_examples.sh script
* Support for PCR with policy. Issue #109
* Progress on PCR policy. Work from John Bland.
* add wrapper functions to seal secrets the NVM with policy authorization
fix the seal and unseal with policy functions to work with non trial policies
update policy examples to allow multiple pcr indicies to be used, currently only 2 can be used because TPML_PCR_SELECTION only allows 2 pcr sellections, may need to be refactored but I didn't want to blow that part of the codebase up
* fix TPM2_SetupPCRSel to correctly use hash type banks
* update policy functions and examples based on pr comments
fixed rsa keys not working due to null default signing algorithm, seal_policy_auth can now be called with no arguments and will pick defaults
* update policy examples based on pcr comments
added error codes and htons macro for use when wolfcrypt is not available
* added policySigned logic to policy seal with nv functions
currently the policy seal with auth nv example is broken due to strange session issues
* Improvements to the session authentication for policy sessions.
* update the sealNV functions, add PolicyRestart and manual htnos
wolfTPM2_SealWithAuthSigNV allows for sealing secrets to NV with just the public part of the sealing key and a pre signed signature so that the private part of the key can be kept off the system. PolicyRestart was added to make reseting the policyDigest easy and a manual htnos function was added for use in wolfBoot
* update policy code based on pr comments
* reconfigure wolfTPM after setting up ibm simulator
* define XREWIND in wolfTPM since it is no longer in wolfssl
* fix scan-build warnings
* remove RSA_SIG_SZ
* use signed char in HexCharToByte for strict build options
* update based on pr comments

* Examples working on Windows and SWTPM
* Check command availability (including for windows blocking it).
* update unseal to work without persistent NV storage
* cleanup cmake from review
* fix a few spelling mistakes
* Fix for `wolfTPM2_NVCreateAuth` to return `TPM_RC_NV_DEFINED` if already exists (it used to do this, but broke with GPIO changes).
* Fixes for building wolfTPM with wolfCrypt only (no TLS).
* Fix for building without RSA and ECC.
* Fix for `--enable-smallstack` with parameter encryption,
* Fix for nvram/store unused variable.
When wolfcrypt is not enabled:
* examples/keygen/keyload failed without error message
* examples/seal/seal did not generate an error message
* examples/seal/unseal was missing conditional compiling
Now, this is fixed.
