This is an update of Aaron's v3 [1].
There are a fair number of changes beyond a mere rebase:
* Updates to the test cases which fail with the new features.
* Updates to the documentation.
* Preserve pauth feature set when changing pauth algorithm.
* Rearrange feature detection:
- Add ARMPauthFeature
- Use it with isar_feature_pauth_feature
- Remove many of the isar predicates
The pauth_auth and pauth_addpac routines wind up making lots
of tests against the pauth feature set. Rather than recompute
the feature set many times for each predicate, compute it once
and compare against the enumerators.
* Algorithmic simplification of Pauth2 and FPAC using cmp_mask.
