Measure asymmetric keys used for verifying file signatures, certificates, etc. This patch defines a new IMA hook namely ima_post_key_create_or_update() to measure the payload used to create a new asymmetric key or update an existing asymmetric key. Asymmetric key structure is defined only when CONFIG_ASYMMETRIC_PUBLIC_KEY_SUBTYPE is defined. Since the IMA hook measures asymmetric keys, the IMA hook is defined in a new file namely ima_asymmetric_keys.c which is built only if CONFIG_ASYMMETRIC_PUBLIC_KEY_SUBTYPE is defined.
