* acme/autocert/internal/acmetest: don't validate in goroutine

In the test server, rather than spawning a goroutine to validate
challenges, block on the validation before responding to the client.
This prevents a test race, where testing.T.Logf is called after the
test is completed.

While this has a slight behavioral difference to some production
ACME server implementations (although is behavior allowed in the spec),
the change has little material impact on what we are testing, since
previously the validation would happen so quickly that it would be
indistinguishable from the new blocking behavior (i.e. we would not be
sending multiple requests during polling previously.)

* acme/autocert: fix renewal timer issue

Block when creating the renewal timer, rather than doing it in a
goroutine. This fixes an issue where startRenew and stopRenew are called
very closely together, and due to lock ordering, stopRenew may be called
before startRenew, resulting in the appearance that the renewal timer
has been stopped before it has actually been created.

This is only an issue in tests, as that is the only place stopRenew is
actually used. In particular this issue manifests in TestGetCertiifcate
sub-tests, where a httptest server reuses a port across two of the
sub-tests. In this case, the renewal calls end up creating dirty state
for the subsequent test, which can cause confusing behavior (such as
attempting to register an account twice.)

Another solution to this problem would be introducing a bool, protected
by renewalMu, which indicates if renewal has been halted, and to check
it in startRenew to check if stopRenew has already been called, which
would allow us to continue calling startRenew in a goroutine and relying
on renewalMu locking for ordering. That said I don't see a particularly
strong reason to call startRenew concurrently, so this seems like the
simplest solution for now.

* bcrypt: reject passwords longer than 72 bytes

By design, bcrypt only uses the first 72 bytes of a password when
generating a hash. Most implementations, including the reference one,
simply silently ignore any trailing input when provided passwords longer
than 72 bytes. This can cause confusion for users who expect the entire
password to be used to generate the hash.

In GenerateFromPassword, reject passwords longer than 72 bytes.
CompareHashAndPassword will still accept these passwords, since we
cannot break hashes that have already been stored.

This makes the automated update workflow simpler.

Also switch the ordering from human readable subject (which is not
necessarily unique), to the raw SPKI (which should always be unique).
This makes it somewhat harder to read to a human (since it'll appear a
little jumbled) but results in a stable sort.

Note this results in adding two new roots, which were added since we
last generated the bundle.

Package fallback has no API; its only purpose is to automatically call
x509.SetFallbackRoots with a set of fallback roots. That API was added
in Go 1.20, hence the go1.20 build constraint in fallback.go.

Add that constraint to bundle.go too, so that it fails to build rather
than quietly being a no-op in Go 1.19.

Also simplify Write(fmt.Sprintf()) into fmt.Fprintf while here.

Add a temporary workaround for go.dev/issue/52287.
It has no effect on the public API in this module.

* ssh: fix RSA certificate and public key authentication with older clients

After adding support for rsa-sha2-256/512 on the server side some edge
cases started to arise with old clients:

1) public key authentication with gpg-agent < 2.2.6 fails because we
   receive ssh-rsa as signature format and rsa-sha2-256 or rsa-sha2-512
   as algorithm.
   This is a bug in gpg-agent fixed in this commit:

   https://github.com/gpg/gnupg/commit/80b775bdbb852aa4a80292c9357e5b1876110c00

2) certificate authentication fails with OpenSSH 7.2-7.7 because we
   receive ssh-rsa-cert-v01@openssh.com as algorithm and rsa-sha2-256
   or rsa-sha2-512 as signature format.

This patch is based on CL 412854 and has been tested with every version
of OpenSSH from 7.1 to 7.9 and OpenSSH 9.3.

* internal/wycheproof: skip all tests in short test mode

The testdata for this package is around 8 MB and downloaded dynamically
via 'go mod download' from its canonical source rather than being copied
to this repository. We're moving towards disallowing all network use in
short test mode, including proxy.golang.org, so add a corresponding test
skip.

Needing to lookup a go test flag is unfortunate, but I don't know of a
less bad available option while the test does the download in TestMain.

On balance, it becomes viable to no longer disable the checksum database
since the test will only run on builders that permit internet use and so
sum.golang.org should just work.

* sha3: have ShakeHash extend hash.Hash

Package sha3 recommends the SHAKE functions for new uses, but this is
currently somewhat inconvenient because ShakeHash does not implement
hash.Hash. This is understandable, as SHAKE supports arbitrary-length
outputs whereas hash.Hash only supports fixed-length outputs. But
there's a natural fixed-length output to provide: the minimum output
that still provides SHAKE's full-strength generic security.

While here, tweak Sum so that its temporary buffer can be stack
allocated.

Also, tweak the panic message in Write so that the error text is more
readily understandable to Go programmers without needing to be
familiar with crypto jargon, and add a similar check in Sum.

This patch updates uses within this repository to use stdlib instead of
depending on the wrapper. With this patch applied, the only remaining
use of the wrapper is in ed25519_test, which appears to be in place to
verify compatibility of the wrapper itself.

the certdata.txt file media type is expected to be plain text.
Check that it is before proceeding with parsing it.

Might help avoid repeats of CL 535735.

* x509roots: catch the zero-roots case when generating the bundle

If the parser returns zero roots, don't attempt to completely remove
the bundle. This may happen if, i.e., the HTTP response is 200 but has
no content. An example of this may be http://go.dev/cl/535735.

* ssh: add test case against ssh CLI

These tests try to ensure better compatibility of our server implementation
with the ssh CLI.

With these tests in place:

1) before merging CL 447757 we would have noticed that our server
   implementation was broken with OpenSSH 8.8+
2) after merging CL 447757 we would have noticed that our server
   implementation was broken with OpenSSH 7.2-7.7

The ssh CLI from $PATH is used by default, but can be overridden using
the SSH_CLI_PATH environment variable.

* crypto/hkdf: remove useless call to Reset

HKDF is commonly used to read keys that are the the same length (or
smaller) than the size of the hash digest, which means the loop inside
Read only runs once.

In that case, calling Reset is unnecesssary overhead.
