cmd/cgo/internal/swig,cmd/go: skip swig tests on 386
We recently added a C++ toolchain to the image, and this is causing
problems on 386 and clang builders. The likely culprit is that we're
missing 32-bit C++ libraries on the builders.
Even if this theory is wrong, these tests *never* ran (always skipped,
or truly never ran) on these platforms, so just skip them for now. We
can look into getting the libraries installed later, but skip for now
to unblock the builders.
There are also problems with clang, but I believe they'll be resolved by
setting CXX to clang++ in golangbuild.
For #67698.

os: RemoveAll: fix symlink race for unix
Since all the platforms now support O_DIRECTORY flag for open, it can be
used to (together with O_NOFOLLOW) to ensure we open a directory, thus
eliminating the need to call stat before open. This fixes the symlink race,
when a directory is replaced by a symlink in between stat and open calls.
While at it, rename openFdAt to openDirAt, because this function is (and was)
meant for directories only.
NOTE Solaris supports O_DIRECTORY since before Solaris 11 (which is the
only version Go supports since supported version now), and Illumos
always had it. The only missing piece was O_DIRECTORY flag value, which
is taken from golang.org/x/sys/unix.

iter: deflake TestPull by letting exiting goroutines finish
Currently TestPull is flaky because goroutines spawned to run subtests
exit asynchronously when they finish and TestPull has explicit checks
for the number of existing goroutines.
This is pretty much only a problem between subtests executing, because
within each subtest the coroutine goroutine spawned for iter.Pull always
exits fully synchronously before the final `next` or `stop` returns.
So, we can resolve the problem by ensuring the first goroutine count the
test takes likely doesn't contain any exiting goroutines. The trick is
to set GOMAXPROCS=1 and spin in runtime.Gosched until the number of
goroutines stabilizes to some reasonable degree (we pick 100 consecutive
iterations; there are only a handful of possible goroutines that can
run, so this is giving that handful around 20 chances to actually run to
completion).
When running TestPull under stress2, this issue is easily reproducible
before this CL. After this CL, it no longer reproduces under these
conditions.

net/http: remove TestTransportDialCancelRace
This test was added to cover a specific race condition
in request cancellation, applying only to the deprecated
Transport.CancelRequest cancellation path. The test
assumes that canceling a request at the moment
persistConn.RoundTrip begins guarantees that it will
be canceled before being sent.
This does not apply to the newer forms of canceling
a request: Request.Cancel and context-based cancellation
both send the cancel signal on a channel, and do not
check for cancellation before sending a request.
A recent refactoring unified the implementation
of cancellation, so the Transport.CancelRequest
path now translates into context-based cancellation
internally. This makes this test flaky, since
sometimes the request completes before we read
from the context's done channel.
Drop the test entirely. It's verifying the fix
for a bug in a code path which no longer exists,
and the property that it's testing for (canceling
a request at a very specific point in the internal
request flow) is not interesting.

crypto/tls: add ech client support
This CL adds a (very opinionated) client-side ECH implementation.
In particular, if a user configures a ECHConfigList, by setting the
Config.EncryptedClientHelloConfigList, but we determine that none of
the configs are appropriate, we will not fallback to plaintext SNI, and
will instead return an error. It is then up to the user to decide if
they wish to fallback to plaintext themselves (by removing the config
list).
Additionally if Config.EncryptedClientHelloConfigList is provided, we
will not offer TLS support lower than 1.3, since negotiating any other
version, while offering ECH, is a hard error anyway. Similarly, if a
user wishes to fallback to plaintext SNI by using 1.2, they may do so
by removing the config list.
With regard to PSK GREASE, we match the boringssl behavior, which does
not include PSK identities/binders in the outer hello when doing ECH.
If the server rejects ECH, we will return a ECHRejectionError error,
which, if provided by the server, will contain a ECHConfigList in the
RetryConfigList field containing configs that should be used if the user
wishes to retry. It is up to the user to replace their existing
Config.EncryptedClientHelloConfigList with the retry config list.

runtime: skip tracing events that would cause reentrancy
Some of the new experimental events added have a problem in that they
might be emitted during stack growth. This is, to my knowledge, the only
restriction on the tracer, because the tracer otherwise prevents
preemption, avoids allocation, and avoids write barriers. However, the
stack can grow from within the tracer. This leads to
tracing-during-tracing which can result in lost buffers and broken event
streams. (There's a debug mode to get a nice error message, but it's
disabled by default.)
This change resolves the problem by skipping writing out these new
events. This results in the new events sometimes being broken (alloc
without a free, free without an alloc) but for now that's OK. Before the
freeze begins we just want to fix broken tests; tools interpreting these
events will be totally in-house to begin with, and if they have to be a
little bit smarter about missing information, that's OK. In the future
we'll have a more robust fix for this, but it appears that it's going to
require making the tracer fully reentrant. (This is not too hard; either
we force flushing all buffers when going reentrant (which is actually
somewhat subtle with respect to event ordering) or we isolate down just
the actual event writing to be atomic with respect to stack growth. Both
are just bigger changes on shared codepaths that are scary to land this
late in the release cycle.)

cmd/compile: keep closure pointer live for range body closures
For range-over-function, the compiler generates a hidden closure
for the range body, and call the iterator function with the hidden
closure as the yield parameter. For debuggers, if it stops inside
the range body (hidden closure), it needs some way to find the
outer function (that contains the range statement), to access the
variables that are in scope. To do this, we keep the closure
pointer live on stack with a special name ".closureptr", so the
debugger can look for this name and find the closure pointer. In
the usual case, the closure is a struct defined in the outer
frame, so following the pointer it will find the frame. We do this
in SSA generation, so if the range func is inlined and there is no
actual closure, we don't generate any extra code. In the case that
there is an actual closure, it's just a single store to the stack,
so the overhead is still small.

crypto/tls: improved 0-RTT QUIC API
Add synchronous management of stored sessions to QUICConn.

as part of its regular event loop processing.
Fixes #63691
