Stage 5b: the opening evaluates the security area as Go

OpenOptions.evaluator is now evaluateSecurityInput, so that opening a
capsule of format 3 gives the verdicts of Go at step 17: the signature of
alg 1 and every verdict of the form, with the author keys of the options,
and the signature of alg 2 and the seal of seal_type 2 not evaluated
until a reader of CMS is given. notEvaluated stays for a caller that
shows no verdict.

tool/open_go_vectors.go records the verdicts of each capsule of format 3
that opens, with their lines, the key and the label of alg 1 and the
earliest valid seal, and opens the fixtures signed with alg 1 also with
their author key saved, F3, and with another, F4. Every case of
open_cases.json and every case of the mutation corpus that opens gives
those verdicts and lines: format3_signed, format3_unsigned,
format3_signature_unsupported, format3_seal_unsupported,
format3_security_v2 and format3_note all of them, and format3_signed_cms
and format3_sealed the part that needs no reader of CMS.

Stage 4c: steps 9 to 18, the opening of the three formats

lib/src/open.dart and open3.dart port Open and openBody of package capsule
of datekeys-go at c531e93, with the checks, codes, steps and texts of the
reference and the detail of each check: the .dkk of step 9.a, decoded or
still encoded, with its material, its critical extensions, its capsule_id
and its capsule_digest; at least one credential; the clock and the release,
with the rule of step 9 for the failures of its source (sourceFailure);
its verification at step 10; OUTER_TIME_AGE with the tlock stanza;
INNER_ACCESS_AGE with the X25519 identities, those of the .dkk and the key
of words, and the rules of the slots; CONTROL_CBOR, header_binding,
I_PAYLOAD and P; PAYLOAD_AGE streamed, with the padding of format 2
checked and never delivered, and in format 3 the frame of BODY, the area,
the head, each file to the sink with its SHA-256 and the padding, with the
precedence of spec §63; and the commit. A failure of age keeps the code of
the identity that reports it, or is ERR_INTEGRITY with the reason of its
phase, as classify of Go.

openCapsule opens a capsule in memory and openCapsuleSource one that a
ByteSource reads: the prefix of the inspection and the nonce of
PAYLOAD_AGE before the release, then pieces of 1 MiB. lib/src/sink.dart
has ByteSink, for the content of formats 1 and 2 and for each file, and
FileSink, for the files of format 3, as the dst and the Sink of Go, with
MemoryByteSink and MemoryFileSink. Nothing is presented as valid before
step 17 ends: the output is closed only then and aborted after any
failure, and the sink aborted after any failure that follows its begin
(spec §56).

The signature and the seal are stage 5: lib/src/verdicts.dart has the
verdicts and the SecurityEvaluator, given what newSecurityContext and
EvaluateSecurityIn of Go take, which never fails the opening; the default
evaluates nothing. OpenOptions.accept is Accept of Go. And
AgePayloadDecryptor.wipe clears the key of a STREAM left unread.

The tests run open_cases.json and the mutation corpus with the texts and
the checks of Go, in memory and from a source read in pieces; capsules of
several MiB made from the fixtures, for the streaming; a capsule with a
stanza for a key of words; and the caller, the sinks and the evaluator.
open_test.dart runs on Node.js too, with open_vectors.g.dart.
