Cherry-pick three upstream fixes: Parcel position reset in hasException()
so the method doesn't consume reply data (7804743), list_past_alias
enumeration filter inversion (2aac65c), and KeyMetadata alignment with
AOSP semantics — modificationTimeMs, Tag.ORIGIN, KeyDescriptor
normalization (86db5bf).
Additionally, createErrorReply() was missing the empty remote stack
trace header int between the exception message and error code, per
AOSP Status.cpp:196. Binder readers expecting the standard
EX_SERVICE_SPECIFIC wire format would misparse our error replies.
