... or so I hope. The main observation was that we still have both
hash_vcpu_for_each() and hash_domain_for_each(), where the latter was
introduced in 2014/15 to replace the former. Only some eight years
later we can now complete this conversion. Everything else addresses
other things noticed along the road.
01: replace sh_reset_l3_up_pointers()
02: convert sh_audit_flags()'es 1st parameter to domain
03: drop hash_vcpu_foreach()
04: rename hash_domain_foreach()
05: move bogus HVM checks in sh_pagetable_dying()
06: drop a few uses of mfn_valid()
07: L2H shadow type is PV32-only
08: reduce effort of hash calculation
09: simplify conditionals in sh_{get,put}_ref()
10: correct shadow type bounds checks
11: sh_remove_all_mappings() is HVM-only
