e53d10dc04 doc: mark range-over-func as documented
The language change for the accepted range-over-func proposal #61405
was documented in CL 590616. Remove the corresponding 'TODO' entry.

Also improve formatting slightly, and switch to preferred relative
links. They'll work better in the long term and in more contexts.

While here, also simplify the suggested line to preview release notes
locally: setting the -content='' flag explicitly is no longer required
as of CL 589936.

For #65614.

b658265012 net/http: use default HTTP/2 frame scheduler
Use the default frame scheduler (currently round-robin)
rather than overriding the default with the priority scheduler.

The priority scheduler is slow, known buggy, and implements
a deprecated stream prioritization mechanism. The default
changed in x/net about a year ago, but we missed that net/http
is overriding that default.

Fixes #67706

cc95d85fe4 cmd/compile: remove quoting in favor of clearer prose in error messages
In an attempt to address issue #65790 (confusing error messages),
quoting of names was introduced for some (but not all) names used
in error messages.

That CL solved the issue at hand at the cost of extra punctuation
(the quotes) plus some inconsistency (not all names were quoted).

This CL removes the quoting again in favor or adding a qualifying noun
(such as "name", "label", "package", "built-in" etc.) before a user-
specified name where needed.

For instance, instead of

        invalid argument to `max'

we now say

        invalid argument to built-in max

There's still a chance for confusion. For instance, before an error
might have been

        `sadly' not exported by package X

and now it would be

        name sadly not exported by package X

but adverbs (such as "sadly") seem unlikely names in programs.

This change touches a lot of files but only affects error messages.

Fixes #67685.

Reason for revert: This is part of a patch series that changed the

regression on applications where that is (or became) the bottleneck.

Reason for revert: This is part of a patch series that changed the
handling of contended lock2/unlock2 calls, reducing the maximum
throughput of contended runtime.mutex values, and causing a performance
regression on applications where that is (or became) the bottleneck.

Reason for revert: This is part of a patch series that changed the
handling of contended lock2/unlock2 calls, reducing the maximum
throughput of contended runtime.mutex values, and causing a performance
regression on applications where that is (or became) the bottleneck.

This test verifies that the semantics of the mutex profile for
runtime.mutex values matches that of sync.Mutex values. Without the rest
of the patch series, this test would correctly identify that Go 1.22's
semantics are incorrect (issue #66999).

787414ca48 cmd/cgo/internal/swig: force use of lld for LTO tests on the builders
For whatever reason, on the builders, when using /usr/bin/ld (the
default linker) with -flto we end up with problems. Specifically, the
linker seems to require LLVMgold.so and can't find it. I'm not really
sure why, but what definitely seems to work is forcing use of lld, which
ships with our clang installation on the builders.

Just enforce this on the builders for now; I've actually had very few
problems running this locally (and I think I'm also mixing and matching
linkers and toolchains too...), so it may be related to the version of
clang we're testing with.

This change, along with CL 589295, should fully fix the clang builders.

Fixes #67698.

cad3ed207f cmd/cgo/internal/swig,cmd/go: reenable swig tests on 386
CL 588938 skipped the tests because they were broken to unblock the
builders, but we're fairly certain the reason they were failing is
because we're missing g++-multilib. This change is intended to land once
CL 589175 is deployed.

fa08befb25 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.

a3a584e4ab 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.

Updates #52745.
