This CL comprises some test-only changes adding rigging to support
end-to-end Trust Tokens tests, as well as some first-pass tests
themselves, disabled pending the necessary code landing in the child CL.
The additions:
1. TrustTokenRequestHandler, which is a server responsible for
satisfying issuance and redemption requests and inspecting subsequent
signed requests to confirm invariants hold;
2. signed_request_verification_util.{h, cc} get more utility methods for
parsing and verifying the contents of Sec-Signature headers and SRRs
3. TrustTokenRequestCanonicalizer and TrustTokenRequestSigningHelper's
unit tests get some refactoring in order to share code with the new
end-to-end test infra
4. The tests! They live in //content/test. I'm starting out with simple
end-to-end tests using the Fetch, XHR, and iframe APIs, as well as one
test that makes sure hasTrustToken returns true after a successful
issuance.
