createEnvBlock currently allocates multiple times: at least one to
convert the slice of strings into a NULL separated slice of bytes, and
then again to encode it as UTF-16. The logic to do so is also quite
complex.
This CL simplifies the logic by allocating only once by encoding the
slice of strings into UTF-16 directly using utf16.AppendRune.

In CL 197062, many errors related to go.sum were changed from base.Fatal
to error returns. The malformed go.sum error was lost in the process.
Currently, when go encounters a malformed go.sum file, go will read the
well-formed part of the file and then silently ignore the rest.
The motivation behind moving away from base.Fatal was to make the errors
show up in -json output. Simply propagating the malformed go.sum error
would not achieve this:
- For an argument-less 'go mod download -json' with a go>=1.17 module,
a malformed go.sum causes an error during LoadModGraph already, before
go ever starts downloading modules and printing their JSON.
- In other cases, a malformed go.sum would be reported as Error for one
of the modules (presumably the one which gets downloaded first) but
none of the others.
- In either case, 'go mod download' manages to download enough data to
succeed on a re-run, making the error look intermittent.
Switch the error back to a Fatal one, but give 'go mod tidy' an
exception to let it fix broken go.sum files.

CL 525556 started using timeRE regexp to match time output from JSON
handler, and relaxed it to allow arbitrary (rather than fixed 3 digit)
precision.
What it missed is in JSON handler the fractional part is omitted
entirely (together with the decimal dot) when the nanoseconds field is
0.
As a result, there are occasional CI failures in js/wasm (which, I guess,
has better chances to return zero nanoseconds).
To fix the flaky test, let's use two different regular expressions,
tailored to text and JSON.

In CL 475375 the Go command started to generate the "preferlinkext"
token file for "strange/dangerous" compiler flags. This serves as a hint
to the Go linker whether to call the external linker or not.
Permit compiler flags used by bazel and bazelbuild/rules_go during
compilation of cgo code to not prefer external linking. This restores
the behavior of previous versions of Go.
As a side effect, it also allows these flags to appear
in #cgo directives in source code. We don't know of any cases
where that is actually useful, but it appears to be harmless
and simplifies the implementation of the internal linking change.

When parsing patterns and matching, split the path into segments at
slashes, then unescape each segment.
This behaves as most people would expect:
- The pattern "/%61" matches the paths "/a" and "/%61".
- The pattern "/%7B" matches the path "/{". (If we did not unescape
patterns, there would be no way to write that pattern: because "/{"
is a parse error because it is an invalid wildcard.)
- The pattern "/user/{u}" matches "/user/john%2Fdoe" with u set to
"john/doe".
- The unexpected redirections of #21955 will not occur.
A later CL will restore the old behavior behind a GODEBUG setting.

When reviewing https://go-review.googlesource.com/c/go/+/522435,
Cherry Mui cherryyz@google.com noticed that the implementation of
StructOf was broken, and produced junk if an interface was embedded
into a struct. For example, StructOf messed up the calling convention
for methods of the embedded interface:
> The main problem is that the method wrappers created by reflect.MakeFunc
> expects to be called with a closure calling convention, with a closure
> context passed in the context register. But methods are called with
> a different calling convention, without setting the closure register,
> because (besides this case) all methods are top level functions.
> So there is no way to pass that makefunc closure context.
It is curious that StructOf did not break in go 1.17 which introduced
the regabi. I've tried to run the following example program, and it
fails even in 1.7 which introduced StructOf.
As the embedding of interfaces has been broken since forever,
let us not perpetuate the complexity that this feature brings,
and just remove the support for embedding altogether.
The test program:
package main
import (
"fmt"
"reflect"
)
type I interface {
F()
}
type T int
func (t T) F() { println(t) }
func main() {
var i I
t := reflect.StructOf([]reflect.StructField{
{
Anonymous: true,
Name: "I",
Type: reflect.TypeOf(&i).Elem(),
},
})
v := reflect.New(t).Elem()
v.Field(0).Set(reflect.ValueOf(T(42)))
fmt.Println(v)
v.Interface().(interface{ F() }).F() // fatal error
}

After CL 528817, *sigctxt.fault of all arches return uintptr, so
there is no need to convert 'c.fault()' to uintptr anymore.

Windows APIs are normally not arch-specific, so it's better to
implement them in Go instead of assembly.
It was previously implemented in assembly because it was the only way
to support calls without a valid g. This CL defines a new function,
stdcall_no_g, that can be used in such cases.
While here, I've also replaced the use of the deprecated syscall
NtWaitForSingleObject with WaitForSingleObject. The former may
give the illusion of being more accurate, as it takes a higher
resolution timeout, but it's not. Windows time resolution is 15.6ms,
and can be as high as 1ms when using a high resolution timer, which
WaitForSingleObject supports.

Also explicitly look up user "nobody" (or "gopher" on the Go builders)
if running as root, instead of hard-coding UID/GID 99.

No test case because the problem can only happen for invalid data. Let
the fuzzer find cases like this.

1. Remove the use of fmt.Sprintf from t.Fatal.
2. Check for errors from initFromJSON.
3. Move 'overlay=0' to a separate cleanup function, for clarity.
