Add a section on the representation of values:
distinguish between values that are self-contained
and values that contain references while avoiding
the notion of "reference types" which is misleading.
Also, use "predeclared identifier nil" rather than
"predeclared value nil" because it is the identifier
that is predeclared.

Turns out that recomputing them (and qInv in particular) in constant
time is expensive, so let's not throw them away when they are available.
They are much faster to check, so we now do that on precompute.
Also, thanks to the opaque crypto/internal/fips140/rsa.PrivateKey type,
we now have some assurance that the values we use are always ones we
checked.
Recovers most of the performance loss since CL 630516 in the happy path.
Also, since now we always use the CRT, if necessary by running a
throwaway Precompute, which is now cheap if PrecomputedValues is filled
out, we effectively fixed the JSON round-trip slowdown (#59695).

We are severely limited by the crypto/rsa API in a few ways:
- Precompute doesn't return an error, but is the only function allowed
to modify a PrivateKey.
- Clients presumably expect the PrecomputedValues big.Ints to be
populated after Precompute.
- MarshalPKCS1PrivateKey requires the precomputed values, and doesn't
have an error return.
- PrivateKeys with only N, e, and D have worked so far, so they might
have to keep working.
To move precomputation to the FIPS module, we focus on the happy path of
a PrivateKey with two primes where Precompute is called before anything
else, which match ParsePKCS1PrivateKey and GenerateKey.
There is a significant slowdown in the Parse benchmark due to the
constant-time inversion of qInv. This will be addressed in a follow-up
CL that will use (and check) the value in the ASN.1.
Note that the prime product check now moved to checkPrivateKey is broken
(Π should start at 1 not 0) and fixed in CL 632478.

This makes three related changes that work particularly well together
and would require significant extra work to do separately: it replaces
X25519Kyber768Draft00 with X25519MLKEM768, it makes CurvePreferences
ordering crypto/tls-selected, and applies a preference to PQ key
exchange methods over key shares (to mitigate downgrades).
TestHandshakeServerUnsupportedKeyShare was removed because we are not
rejecting unsupported key shares anymore (nor do we select them, and
rejecting them actively is a MAY). It would have been nice to keep the
test to check we still continue successfully, but testClientHelloFailure
is broken in the face of any server-side behavior which requires writing
any other messages back to the client, or reading them.

When enabled, the server checks new connections for

For Transport, enabling UnencryptedHTTP2 and disabling HTTP1

Adds support for server-side ECH.
We make a couple of implementation decisions that are not completely
in-line with the spec. In particular, we don't enforce that the SNI
matches the ECHConfig public_name, and we implement a hybrid
shared/backend mode (rather than shared or split mode, as described in
Section 7). Both of these match the behavior of BoringSSL.
The hybrid server mode will either act as a shared mode server, where-in
the server accepts "outer" client hellos and unwraps them before
processing the "inner" hello, or accepts bare "inner" hellos initially.
This lets the server operate either transparently as a shared mode
server, or a backend server, in Section 7 terminology. This seems like
the best implementation choice for a TLS library.

Add a new function, WithDataIndependentTiming, which takes a function as
an argument, and encloses it with calls to set/unset the DIT PSTATE bit
on Arm64.
Since DIT is OS thread-local, for the duration of the execution of
WithDataIndependentTiming, we lock the goroutine to the OS thread, using
LockOSThread. For long running operations, this is likely to not be
performant, but we expect this to be tightly scoped around cryptographic
operations that have bounded execution times.
If locking to the OS thread turns out to be too slow, another option is
to add a bit to the g state indicating if a goroutine has DIT enabled,
and then have the scheduler enable/disable DIT when scheduling a g.
Additionally, we add a new GODEBUG, dataindependenttiming, which allows
setting DIT for an entire program. Running a program with
dataindependenttiming=1 enables DIT for the program during
initialization. In an ideal world PSTATE.DIT would be inherited from
the parent thread, so we'd only need to set it in the main thread and
then all subsequent threads would inherit the value. While this does
happen in the Linux kernel [0], it is not the case for darwin [1].
Rather than add complex logic to only set it on darwin for each new
thread, we just unconditionally set it in mstart1 and cgocallbackg1
regardless of the OS. DIT will already impose some overhead, and the
cost of setting the bit is only ~two instructions (CALL, MSR), so it
should be cheap enough.

This re-enables the behavior of CL 536399 (by effectively reverting CL
628955), so now go test -json again includes build output and failures
as JSON rather than text.
However, since this behavior is clearly enough to trip up some build
systems, this CL includes a GODEBUG=gotestjsonbuildtext that can be
set to 1 to revert to the old behavior.

Currently, if a test or imported package fails to build during "go
test -json", the build error text will be interleaved with the JSON
output of tests. Furthermore, there’s currently no way to reliably
associate a build error with the test package or packages it affected.
This creates unnecessary friction and complexity in tools that consume
the "go test -json" output.
This CL makes "go test -json" enable JSON reporting of build errors.
It also adds a "FailedBuild" field to the "fail" TestEvent, which
gives the package ID of the package that failed to build and caused
the test to fail.
Using this, CI systems should be able to consume the entire output
stream from "go test -json" in a structured way and easily associate
build failures with test failures during reporting.

A GODEBUG is actually a security risk here: most programs will start to
ignore errors from Read because they can't happen (which is the intended
behavior), but then if a program is run with GODEBUG=randcrash=0 it will
use a partial buffer in case an error occurs, which may be catastrophic.
Note that the proposal was accepted without the GODEBUG, which was only
added later.

"have the same sequence of fields, and if corresponding fields have the
same names, and identical types, and identical tags" for the structs to

The implementation (forever) has also required that two corresponding
fields are either both embedded or not embedded. This is arguably part
of a struct's structure but is not explicitly specified.
This CL makes a minor change to the prose to address that.

A previous change [1] was introduced to enable MPTCP by default
for both the clients and servers, based on the discussions [2] in
golang#56539, where MPTCP would be an opt-in for a release or
two, and then would become an opt-out.
This change was not accepted at the time because the support for
a few socket options was missing [3]. Now that this support has been
added [4] and backported to stable versions not to block MPTCP
deployment with Go, it sounds like a good time to reconsider the use
of MPTCP by default.
Instead of enabling MPTCP on both ends by default, as a first step,
it seems safer to change the default behaviour only for the server
side (Listeners). On the server side, the impact is minimal: when
clients don't request to use MPTCP, server applications will create
"plain" TCP sockets within the kernel when connections are accepted,
making the performance impact minimal. This should also ease
experiments where MPTCP is enabled by default on the client side
(Dialer).
The changes in this patch consist of a duplication of the mptcpStatus
enumeration to have both a mptcpStatusDial and a mptcpStatusListen,
where MPTCP is enabled by default in mptcpStatusListen, but disabled
by default in mptcpStatusDial. It is still possible to turn MPTCP support
on and off by using GODEBUG=multipathtcp=1.

Some tests need to use os.Chdir, but the use is complicated because
- they must change back to the old working directory;
- they must not use t.Parallel.
Add Chdir that covers these cases, and sets PWD environment variable
to the new directory for the duration of the test for Unix platforms.
Unify the panic message when t.Parallel is used together with t.Setenv
or t.Chdir.
Add some tests.
For #62516.

The spec says that an embedded field must be specified
as a type name (or a pointer to a type name). This is
explicit in the prose and the FieldDecl syntax.
However, the prose on promoted methods required a named
type (originally the term used for a "defined type").
Before the introduction of alias types, type names could
only refer to named/defined types, so the prose was ok.
With the introduction of alias types in Go 1.9, we
distinguished between defined types (i.e., types given
a name through a type declaration) and type aliases
(types given an alternative name), and retired the notion
of a named type since any type with a name (alias type
and defined type) could be considered a "named type".
To make things worse, with Go 1.18 we re-introduced the
notion of a named type which now includes predeclared
types, defined types, type parameters (and with that
type aliases denoting named types).
In the process some of the wording on method promotion
didn't get updated correctly. At attempt to fix this
was made with CL 406054, but while that CL's description
correctly explained the intent, the CL changed the prose
from "defined type" to "named type" (which had the new
meaning after Go 1.18), and thus did not fix the issue.
This CL fixes that fix by using the term "type name".
This makes the prose consistent for embedded types and
in turn clarifies that methods of embedded alias types
(defined or not) can be promoted, consistent with the
implementation.
While at it, also document that the type of an embedded
field cannot be a type parameter. This restriction has
been in place since the introduction of type parameters
with Go 1.18 and is enforced by the compiler.
Fixes#66540.
For #41687.

(Second attempt at CL 529816 (f1d6050), reverted in
CL 571695 (1304d98) due to broken longtest builder.)
The tests analyser reports structural problems in test
declarations. Presumably most of these would be caught by
go test itself, which compiles and runs (some subset of) the
tests, but Benchmark and Fuzz functions are executed less
frequently and may benefit more from static checks.
A number of tests of "go vet" needed to be updated, either
to avoid mistakes caught by the analyzer, or to suppress
the analyzer when the mistakes were intended.
Also, reflect the change in go test help message.
