The ndk_platform backend will soon be deprecated because the ndk backend
can serve the same purpose. This is to eliminate the confusion about
having two variants (ndk and ndk_platform) for the same 'ndk' backend.

This change removes hardware/interfaces/identity's dependency on its own
libcppbor copy. The copy can not be fully removed until various vendor
dependencies are cleaned up.
Superficial changes are made to the VTS tests to match the slightly
altered namespace on some of the functions.
This migration is a prerequisite for getting the
IRemotelyProvisionedComponent functionality into system/keymaster.
Without migrating to the same library, the build system runs into issues
since there are "two" libcppbor libraries with conflicting namespaces
otherwise.

Introduce platform-neutral C library ("libeic") which can be used to
implement an Identity Credential Trusted Application/Applet in Secure
Hardware.
The libeic library is intentionally low-level, has no dependencies
(not even libc), uses very little run-time memory (less than 500 bytes
during a provisioning or presentation session), and doesn't
dynamically allocate any memory. Crypto routines are provided by the
library user through a simple crypto interface defined in EicOps.
Also provide an Android-side HAL implementation designed to
communicate with libeic running in Secure Hardware outside
Android. Abstract out communications between HAL and TA in a couple of
SecureHardwareProxy* classes which mimic libeic 1:1.
The default implementation of the HAL is a combination of the
aforementioned HAL using libeic in-process backed by BoringSSL for the
crypto bits.

- The docs said that IdentityCredential.createEphemeralKey() returned
data encoded PKCS#8 which is wrong. It's supposed to be in DER format
which is also what the VTS tests and credstore expects.
- Clarify that createEphemeralKeyPair(), setReaderEphemeralPublicKey(),
and createAuthChallenge() are all optional.
- Avoid passing an invalid profile ID in the IdentityCredentialTests.
verifyOneProfileAndEntryPass test.
- Update requirements for which tags must be present in the attestation
for CredentialKey as well as the requirements on expiration date and
the issuer name. Update default implementation to satisfy these
requirements. Update VTS tests to carefully verify these requrements
are met.
- Clarify requirements for X.509 cert for AuthenticationKey. Add VTS
test to verify.
- Mandate that TAG_IDENTITY_CREDENTIAL_KEY must not be set for test
credentials. Add VTS test to verify this.
- Make default implementation pretend to be implemented in a trusted
environment and streamline VTS tests to not special-case for the
default implementation.
- Switch to using the attestation extension parser from the KM 4.1
support library instead of the one from system/keymaster. The latter
one did not support the latest attestation extension and thus would
fail for pretty much anything that wasn't the default HAL impl.
- Fix a couple of bugs in keymaster::V4_1::parse_attestation_record():
- Report root_of_trust.security_level
- Add support for Tag::IDENTITY_CREDENTIAL_KEY
- Fix how EMacKey is calculated.

Checking cert_info->key->algor->algorithm is redundant with the checks
following it. If the public key is an EC key, that was the OID. Remove
the check so this code does not break when BoringSSL makes the X509

While we're not particularly aiming to make ECDSA_SIG opaque, getters
exist, so go ahead and use them.

Some IC applications may perform two requests - one to get data
elements and a second empty request. The latter is to e.g. get an
empty DeviceSignedItems and corresponding MAC.

namespace.

Key derivation for session encryption and MACing now involves mixing
in SessionTranscriptBytes. Update docs, default implementation, and
VTS tests to reflect this.
Also, the standard changed such that instead of DeviceAuthentication
being MACed or signed, it's instead DeviceAuthenticationBytes which is
defined as #6.24(bstr .cbor DeviceAuthentication). The same also for
ReaderAuthentication, now ReaderAuthenticationBytes is the CBOR which
is signed by the reader.
Also update the URL for CDDL since it's now a published RFC.

batch certificate.
- Require challenge passed to getAttestationCertificate() is
non-empty.
- Fix bug in VTS tests where the startPersonlization() result was not
checked.
- Remove verifyStartPersonalizationZero test since it cannot be

- Ensure secureUserId is non-zero if user authentication is needed.
- Specify format for signingKeyBlob in generateSigningKeyPair() same
way we do for credentialData in finishAddingEntries().
- Modify EndToEndTest to decrypt/unpack credentialData to obtain
credentialPrivKey and storageKey and do cross-checks on these.
- Modify EndToEndTest to decrypt/unpack signingKeyBlob to obtain
signingKeyPriv and check it matches the public key in the returned
certificate.
- Add new VTS tests for user and reader authentication.
- Relax unnecessary requirements about SessionTranscript structure -
just require it has X and Y of the ephemeral key created earlier.
- Allow calls in VTS tests to v2 HAL to fail - this should allow
these VTS tests to pass on a compliant v1 HAL.
