If there were no secure keymasters on a device, but software keymasters
offered, then keystore would shuffle the software keymaster to the
TRUSTED_ENVIRONMENT securityLevel keymaster slot and generate a software
fallback keymaster. This change lets the software keymaster slot occupy
both the default and software slot. A fallback keymaster implementation
should only be invoked if there actually is no other keymaster
implementation.

This is the first part of the update, adjusting keystore to use the
KM4.1 interface, but not call any of the new methods. That will come
in a subsequent CL.

This was needed because credstore needs to generate and pass the
generated AttestationApplicationId to the Identity Credential HAL.

The results of TEMP_FAILURE_RETRY can be negative in an error
case. But we were assigning it to an unsigned size_t, and
thus our check to see if it was negative would always be false.
We switch to storing this result in a signed ssize_t, so we'll
properly handle a negative return value. As long as we're
never writing more than 2GB (ssize_t max on a 32-bit system),
this shouldn't be a problem.

The credstore system daemon is sitting below the Identity Credential
Framework APIs and on top of the Identity Credential HALs. Its main
job is to store credential data and provide a way for applications to
communicate with the secure hardware abstracted by the HAL.
This daemon runs as an unprivileged user, credstore.
The auth-tokens needed by credstore are supplied by keystore and this
CL includes the requisite changes to keystore for this to work.

Keystore's security originally derived from encrypting keys with a key
derived from the user's password. To avoid making keystore into a
password brute force oracle, keystore cleared itself after five
incorrect presentations. All of this has been superseded by moving
keystore's security into Keymaster, and by moving password security
into Gatekeeper/Weaver, and further by implmenting the synthetic
password model.
This CL removes the now-useless and occasionally-dangerous keystore
self-destruct.

ag/5984229 that added support for AES-256 master keys inadvertently
caused them not to be encyrpted by the user's password. This is less
damaging to security than it might appear because these keys are also
encrypted by Keymaster, in the TEE or StrongBox.

Test: Manually verify password is encryption on a userdebug build.
