SessionTicketsDisabled is false.

Minimal amount of changes needed to switch to GO 1.11
* crypto/internal/cipherhw was removed and internal/cpu was introduced
* wrong code formatting in handhsake_server_test.go was breaking
the build
* includes AD in authentication check of TLS records
As per 5.2 of TLS 1.3 draft-28, the additional data is record header.
* tests: Update tests in order to support draft-28
* Interoperability: Updates NSS and BoringSSL versions to the
one supporting draft-28
* Bogo: Updates revision number to use tests for draft-28
* FIX: makefile was using test-compat target instead of
test-interop
* DC test: constify
* Use binary interface to encode in big-endian
This is merge of commit 5158aab7d662e274aed870ae6bf9cf8ae0786f5b
from https://github.com/golang/go.git for go/crypto/tls only.
iana.org, www.iana.org and data.iana.org all present a valid TLS
certificate, so let's use it when fetching data or linking to
resources to avoid errors in transit.

Draft 21 changed end_of_early_data from an alert into a handshake
message to allow it to integrate better with the handshake. This change
does that, rather than handling EOD at the record layer, it moves
processing up to the actual readers of (early) application data.
D19 added an additional pre-extract Derive-Secret stage. D20 shortened
labels. Bump from D18 to D21 with no backwards compat option for now
since older drafts are considered undeployable.
Until PSS support is finalized for TLS 1.2, let's not advertise support
for that. Since TLS 1.3 however mandates PSS, we have no other option
than advertising this even if we have not added complete support.
Another reason why I apply it to just TLS 1.3 and not 1.2 is because the
latter would require updating the testdata.
This adds support for RSASSA-PSS signatures in handshake messages as
required by TLS 1.3. Even if TLS 1.2 is negotiated, it must support PSS
when advertised in the Client Hello (this will be done later as the
testdata will change).

Merge serverHelloMsg13 into serverHelloMsg in preparation for draft 22.
This will also simplify the client implementation since only one
structure has to be checked.
Also fixed potential out-of-bounds access with keyShare unmarshal.
Merge upstream go post-1.9 crypto/tls changes from master:

Conflicts:
* handshake_client.go: conflict between our ("crypto/tls: allow client to
pick TLS 1.3, do not enable it by default.") and upstream
("crypto/tls: split clientHandshake into multiple methods"), resolve
by applying the mutualVersion->pickVersion change in pickTLSVersion.
* handshake_server.go: trivial conflict due to upstreamed patch
("crypto/tls: replace signatureAndHash by SignatureScheme.") and
("crypto/tls: implement TLS 1.3 server 0-RTT") which added pskBinder.
Other merge changes:
* tls13.go: signatureAndHashes as added in ("crypto/tls: implement TLS
1.3 minimal server") was renamed as required by ("crypto/tls: replace
signatureAndHash by SignatureScheme.").
* handshake_client.go: moved check from ("crypto/tls: check that client
cipher suite matches version") to pickCipherSuite as required by
("crypto/tls: split clientHandshake into multiple methods").
In the current implementation, it is possible for a client to
continuously send warning alerts, which are just dropped on the floor
inside readRecord.
This can enable scenarios in where someone can try to continuously
send warning alerts to the server just to keep it busy.
This CL implements a simple counter that triggers an error if
we hit the warning alert limit.

This is the equivalent change to 1c105980 but for SHA-512.
SHA-512 certificates are already supported by default since b53bb2ca,
but some servers will refuse connections if the algorithm is not
advertised in the overloaded signatureAndHash extension (see 09b238f1).
This required adding support for SHA-512 signatures on CertificateVerify
and ServerKeyExchange messages, because of said overloading.
Some testdata/Client-TLSv1{0,1} files changed because they send a 1.2
ClientHello even if the server picks a lower version.
Closes#22422

Consolidate the signature and hash fields (SignatureAndHashAlgorithm in
TLS 1.2) into a single uint16 (SignatureScheme in TLS 1.3 draft 21).
This makes it easier to add RSASSA-PSS for TLS 1.2 in the future.
Fields were named like "signatureAlgorithm" rather than
"signatureScheme" since that name is also used throughout the 1.3 draft.
The only new public symbol is ECDSAWithSHA1, other than that this is an
internal change with no new functionality.

mutualVersion takes a maximum version, but skips TLS 1.3 because this
version is not negotiated via ClientHello.legacy_version. The server
however still uses its ServerHello.version field to select a version
from the supported_versions extension and the client must do the same.
A new getSupportedVersions method is introduced to have a single place
to handle the mapping of VersionTLS13 to the draft values.
Remove the MaxVersion override to TLS 1.3, users must set MaxVersion if
they intent to use the experimental TLS 1.3 functionality.
Fixes: ("crypto/tls: make 1.3 version negotiation more robust")
To allow clients to advertise both TLS 1.2 and TLS 1.3 cipher suites,
remove the distinction between both suites. TLS 1.3 suites are now
always included in the default cipher list (and the client will send it
if MaxVersion allows for it).
Since TLS 1.3 is expected to become the default MaxVersion and
applications might have set only TLS 1.2 cipher suites in their
configuration, TLS 1.3 cipher suites are added when none are present.
Alternatively, I considered disallowing overriding the TLS 1.3 suites,
but that requires more complexity and has not much benefits. Provide a
mechanism and do not dictate policy, application developers might want
to fix a cipher suite for testing other implementations for example.
Fixes https://github.com/cloudflare/tls-tris/pull/22
I opted for adding a separate TLS13CipherSuites field to the Config
because library users that did not set Config.MaxVersion are
supposed to get TLS 1.3 support automatically, like it has been for
HTTP/2, but having set CipherSuites would effectively disable it.
