This is the first round of TODOs created based on relnote todo output.
There are many entries that need to be documented, expanded, reworded,
and this change makes progress on setting that up.
For this cycle, relnote todo implemented a simple heuristic of finding
CLs that mention accepted proposals (see issue 62376, or comment
https://go.dev/issue/62376#issuecomment-2101086794 specifically).
The "Items that don't need to be mentioned in Go 1.23 release notes but
are picked up by relnote todo." section in todo.md contains an attempt
at reviewing that list. The large number of items needed to be reviewed
made it impractical to spend much time on any individual one.
For #65614.

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.

The atomic And/Or operators were added by the CL 528797,
the compiler does not intrinsify them, this CL does it for
arm64.
Also, for the existing atomicAnd/Or operations, the updated
value are not used, but at that time we need a register to
temporarily hold it. Now that we have v.RegTmp, the new value
is not needed anymore. This CL changes it.
The other change is that the existing operations don't use their
result, but now we need the old value and not the new value for
the result.
And this CL alias all of the And/Or operations into sync/atomic
package.

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.

The current implementation doesn't resolve as per spec RFC 3986 the case
where the base URL has an opaque value, and the reference doesn't have
either a scheme, authority or path. Currently, this specific case falls
back to the "abs_path" or "rel_path" cases, where the final path results
of the base_path being resolved relatively to the reference's, but since
the opaque value is stored independently, it needs a case of its own.
The algorith for resolving references is defined in RFC 3986 section 5.2.2:

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.)

As of https://go.dev/cl/586796, the runtime/metrics view of internal
mutex contention is sampled at 1 per gTrackingPeriod, rather than either
1 (immediately prior to CL 586796) or the more frequent of
gTrackingPeriod or the mutex profiling rate (Go 1.22). Thus, we no
longer have a real lower bound on the amount of contention that
runtime/metrics will report. Relax the test's expectations again.

Preserving an ordering wherein spans are always named before their
constituents makes parsing much more straightforward.

They were still referencing the old internal/trace/v2 packages, and
gotraceeventstats had an extra layer of cmd directory (not sure why,
maybe it was always like that).
