Reduce the telemetry proposal template to make it easier to file
telemetry proposals. At a high level, the proposal is just a request to
merge a specific configuration change, so a free text rationale as well
as proposed CL link should suffice. The proposal committee can make sure
that all concerns about new uploading are addressed.
Also, fix links to the chartconfig package documentation, as well as the
config.txt file, and reference the new go.dev/doc/telemetry.

This CL modifies the download behavior when downloading a toolchain for 1.21+. Previously, Go would attempt to download 1.X when upgrading the toolchain which would cause the download to fail for 1.21+ since 1.X is an invalid toolchain. We will attempt to download 1.X.0 since that's likely what the user intended.
Additionally, we will also now provide a better error message when the
user provides a language version instead of a toolchain version for
1.21+.

The darwin linker allows setting the LTO library with the -lto_library
flag. This wasn't caught by our "safe linker flags" check because it
was covered by the -lx flag used for linking libraries. This change
adds a specific check for excluded flags which otherwise satisfy our
existing checks.
Loading a mallicious LTO library would allow an attacker to cause the
linker to execute abritrary code when "go build" was called.

If a signal lands on a non-Go thread, and Go code doesn't want to
handle it, currently we re-raise the signal in the signal handler
after uninstalling our handler, so the C code can handle it.
But if there is no C signal handler and the signal is ignored,
there is no need to re-raise the signal. Just ignore it. This
avoids uninstalling and reinstalling our handler, which, for some
reason, changes errno when TSAN is used. And TSAN does not like
errno being changed in the signal handler.
Not really sure if this is the bset of complete fix, but it does
fix the immediate problem, and it seems a reasonable thing to do
by itself.
Test case is CL 581722.

Unfortunately, LLVM TSAN decided to remove OpenBSD support, which
means that the syso files cannot currently be regenerated (see #52090).
The race_openbsd.syso contains a reference to the syscall symbol,
which has been removed from OpenBSD's libc in 7.5. As such, this
means that the race detector no longer works on openbsd/amd64 (at
least until LLVM TSAN support is reinstated for OpenBSD).

The routing tree used for matching ServeMux patterns used the
key "*" to hold a child node for a multi-segment wildcard.
The problem is that "*" is a valid path segment, which confused
the matching algorithm: it would fetch the multi wildcard child
when looking for the literal child for "*".
Eschew clever encodings. Use a separate field in the node to
represent the multi wildcard child.
Fixes#67067.
