Keystore 2.0: Make key blob upgrade atomic. This patch adds a key id lock. load_key_entry now returns a key id guard, and database operations, that manipulate key entries require a valid guard. This is mainly used to make upgrading the key blob atomic. This patch also adds key upgrade to wrapped key import and adds a helper function, that hides the upgrade-required-retry logic. Test: keystore2_test Change-Id: I3f816817c731b89acb651b7d9a5fcacdd46c567f
