69e75c8581 runtime: properly frame panic values in tracebacks
This CL causes the printing of panic values to ensure that all
newlines in the output are immediately followed by a tab, so
that there is no way for a maliciously crafted panic value to
fool a program attempting to parse the traceback into thinking
that the panic value is in fact a goroutine stack.

a63907808d net/http: add field Cookie.Quoted bool
The current implementation of the http package strips double quotes
from the cookie-value during parsing, resulting in the serialized
cookie not including them. This patch addresses this limitation by
introducing a new field to track whether the original value was
enclosed in quotes.

Additionally, the internal representation of a cookie in the cookiejar
package has been adjusted to align with the new representation.

The syntax of cookies is outlined in RFC 6265 Section 4.1.1:
https://datatracker.ietf.org/doc/html/rfc6265\#section-4.1.1

84fbdf01ff cmd/go: use cache for PGO preprocessing
This is the final CL in the series adding PGO preprocessing support to
cmd/go. Now that the tool is hooked up, we integrate with the build
cache to cache the result.

This is fairly straightforward. One difference is that the compile and
link do caching through updateBuildID. However, preprocessed PGO files
don't have a build ID, so it doesn't make much sense to hack our way
through that function when it is simple to just add to the cache
ourselves.

As as aside, we could add a build ID to the preproccessed file format,
though it is not clear if it is worthwhile. The one place a build ID
could be used is in buildActionID, which currently compute the file hash
of the preprocessed profile. With a build ID it could simply read the
build ID. This would save one complete read of the file per build
(cmd/go caches the hash), but each compile process also reads the entire
file, so this is a small change overall.

Fixes #58102.

f1d60500bc cmd/go/internal/test: add 'tests' vet check to 'go test' suite
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.

Also, reflect the change in go test help message.

+ release note

Fixes golang/go#44251

1e433915ce cmd/link,debug/elf: mark Go binaries with no branch target CFI on openbsd
OpenBSD enables Indirect Branch Tracking (IBT) on amd64 and Branch Target
Identification (BTI) on arm64, where hardware permits. Since Go generated
binaries do not currently support IBT or BTI, temporarily mark them with
PT_OPENBSD_NOBTCFI which prevents branch target CFI from being enforced
on execution. This should be removed as soon asn IBT and BTI support are
available.

b09ac10bad os: don't normalize volumes to drive letters in os.Readlink
This CL updates os.Readlink so it no longer tries to normalize volumes
to drive letters, which was not always even possible.

This behavior is controlled by the `winreadlinkvolume` setting.
For Go 1.23, it defaults to `winreadlinkvolume=1`.
Previous versions default to `winreadlinkvolume=0`.

Fixes #63703.

7986e26a39 os: don't treat mount points as symbolic links
This CL changes the behavior of os.Lstat to stop setting the
os.ModeSymlink type mode bit for mount points on Windows. As a result,
filepath.EvalSymlinks no longer evaluates mount points, which was the
cause of many inconsistencies and bugs.

Additionally, os.Lstat starts setting the os.ModeIrregular type mode bit
for all reparse tags on Windows, except for those that are explicitly
supported by the os package, which, since this CL, doesn't include mount
points. This helps to identify files that need special handling outside
of the os package.

This behavior is controlled by the `winsymlink` GODEBUG setting.
For Go 1.23, it defaults to `winsymlink=1`.
Previous versions default to `winsymlink=0`.

e596e88318 path/filepath: add Localize
Add the Localize function, which takes an io/fs slash-separated path
and returns an operating system path.

Localize returns an error if the path cannot be represented on
the current platform.

Replace internal/safefile.FromFS with Localize,
which serves the same purpose as this function.

The internal/safefile package remains separate from path/filepath
to avoid a dependency cycle with the os package.

0e7c9846c4 cmd: don't require build tags in relnote pathnames
Due to a bug in golang.org/x/build/relnote, API features affecting
specific builds would need to include those build tags in relnote
pathnames.

This CL vendors in the fixed golang.org/x/build. (That caused other
modules to be vendored in as well.)

It also renames the syscall relnote file to remove the build tags
from its pathname.

For #64169.
