a939bb9439 fmt: revert "don't pad strings with zeros"
This reverts CL 555776 (commit 704401ffa0).
Scores of tests break inside Google, and there was a test for the old behavior,
so clearly we thought it was correct at one point.

An example of code that broke inside Google is:

	func (pn ProjectNumber) PaddedHexString() string {
		return fmt.Sprintf("%016s", strconv.FormatInt(int64(pn), 16))
	}

Here is another example:

	// IPv4toISO create ISO address base on a given IPv4 address.
	func IPv4toISO(v4 string) (string, error) {
		if net.ParseIP(v4).To4() == nil {
			return "", fmt.Errorf("invalid IPv4 address")
		}
		s := strings.Split(v4, ".")
		var ss string
		for _, n := range s {
			ss = ss + fmt.Sprintf("%03s", n)
		}
		if len(ss) != 12 {
			return "", fmt.Errorf("invalid IPv4 address")
		}
		return fmt.Sprint("49.0001." + ss[0:4] + "." + ss[4:8] + "." + ss[8:12] + ".00"), nil
	}

This is doing the weird but apparently standard conversion from
IPv4 to ISO ISIS Area 1 (see for example [1]).

Here is an example from github.com/netbirdio/netbird:

	func generateNewToken() (string, string, error) {
		secret, err := b.Random(PATSecretLength)
		if err != nil {
			return "", "", err
		}

		checksum := crc32.ChecksumIEEE([]byte(secret))
		encodedChecksum := base62.Encode(checksum)
		paddedChecksum := fmt.Sprintf("%06s", encodedChecksum)
		plainToken := PATPrefix + secret + paddedChecksum
		hashedToken := sha256.Sum256([]byte(plainToken))
		encodedHashedToken := b64.StdEncoding.EncodeToString(hashedToken[:])
		return encodedHashedToken, plainToken, nil
	}

base62.Encode returns a string no leading zeros; the %06s adds leading zeros.

Are there other ways to write these examples? Yes.
Has all this code worked until now? Also yes.

The change to this behavior observed that right padding doesn't
add zeros, only left padding, but that makes sense: in numbers
without decimal points, zeros on the left preserve the value
while zeros on the right change it.

Since we agree that this case is probably not important either way,
preserve the long-time behavior of %0s.

Will document it in a followup CL: this is a clean revert.

Reopen #56486.

ae457e811d net/textproto: reject HTTP requests with empty header keys
According to RFC 7230, empty field names in HTTP header are invalid.
However, there are no specific instructions for developers to deal
with that kind of case in the specification. CL 11242 chose to skip
it and do nothing about it, which now seems like a bad idea because
it has led `net/http` to behave inconsistently with the most widely-used
HTTP implementations: Apache, Nginx, Node with llhttp, H2O, Lighttpd, etc.
in the case of empty header keys.

There is a very small chance that this CL will break a few existing HTTP clients.

Fixes #65244

While here, remove unnecessary uses of types2.Unalias, and add a
missing one in recvBase to handle:

    type T int
    type A = T
    func (*A) m() {}

65f056d07a runtime: avoid new linkname for goroutine profiles
CL 464349 added a new linkname to provide gcount to runtime/pprof to
avoid a STW when estimating the goroutine profile allocation size.

However, adding a linkname here isn't necessary for a few reasons:

1. We already export gcount via NumGoroutines. I completely forgot about
   this during review.
2. aktau suggested that goroutineProfileWithLabelsConcurrent return
   gcount as a fast path estimate when the input is empty.

The second point keeps the code cleaner overall, so I've done that.

For #54014.

0c64be46ac runtime: disable use of runnext on wasm
When readying a goroutine, the scheduler typically places the readied
goroutine in pp.runnext, which will typically be the next goroutine to
run in the schedule.

In order to prevent a set of ping-pong goroutines from simply switching
back and forth via runnext and starving the rest of the run queue, a
goroutine scheduled via runnext shares a time slice (pp.schedtick) with
the previous goroutine.

sysmon detects "long-running goroutines", which really means Ps using
the same pp.schedtick for too long, and preempts them to allow the rest
of the run queue to run. Thus this avoids starvation via runnext.

However, wasm has no threads, and thus no sysmon. Without sysmon to
preempt, the possibility for starvation returns. Avoid this by disabling
runnext entirely on wasm. This means that readied goroutines always go
on the end of the run queue and thus cannot starve via runnext.

Note that this CL doesn't do anything about single long-running
goroutines. Without sysmon to preempt them, a single goroutine that
fails to yield will starve the run queue indefinitely.

For #65178.

5dceddfe7c runtime: use channels in gcBgMarkStartWorkers
gcBgMarkStartWorkers currently starts workers one at a time, using a
note to communicate readiness back from the worker.

However, this is a pretty standard goroutine, so we can just use a
channel to communicate between the goroutines.

In addition to being conceptually simpler, using channels has the
additional advantage of coordinating with the scheduler. Notes use OS
locks and sleep the entire thread, requiring other threads to run the
other goroutines. Waiting on a channel allows the scheduler to directly
run another goroutine. When the worker sends to the channel, the
scheduler can use runnext to run gcBgMarkStartWorker immediately,
reducing latency.

We could additionally batch start all workers and then wait only once,
however this would defeate runnext switching between the workers and
gcBgMarkStartWorkers, so in a heavily loaded system, we expect the
direct switches to reduce latency.

8e02e7b26a go/types, types2: use existing case-insensitive lookup (remove TODO)
Rather than implementing a new, less complete mechanism to check
if a selector exists with different capitalization, use the
existing mechanism in lookupFieldOrMethodImpl by making it
available for internal use.

Pass foldCase parameter all the way trough to Object.sameId and
thus make it consistently available where Object.sameId is used.

From sameId, factor out samePkg functionality into stand-alone
predicate.

Do better case distinction when reporting an error for an undefined
selector expression.

Cleanup.

09ed9a6585 cmd/compile: implement float min/max in hardware for riscv64
CL 514596 adds float min/max for amd64, this CL adds it for riscv64.

The behavior of the RISC-V FMIN/FMAX instructions almost match Go's
requirements.

However according to RISCV spec 8.3 "NaN Generation and Propagation"
>> if at least one input is a signaling NaN, or if both inputs are quiet
>> NaNs, the result is the canonical NaN. If one operand is a quiet NaN
>> and the other is not a NaN, the result is the non-NaN operand.

Go using quiet NaN as NaN and according to Go spec
>> if any argument is a NaN, the result is a NaN

This requires the float min/max implementation to check whether one
of operand is qNaN before float mix/max actually execute.

This CL also fix a typo in minmax test.

93f0c0b25e internal/testenv: allow "-noopt" anywhere in builder name in test
testenv's TestHasGoBuild test is supposed to allow noopt builders to not
have go build, but the pattern match is failing on the LUCI builders
where a test shard might have an additional "-test_only" suffix in the
builder name. Furthermore, in the LUCI world, "run mods" (the builder
type suffixes) are supposed to be well-defined and composable, so it
doesn't make sense to restrict "-noopt" to the builder suffix anyway.

This change modifies the test to allow "-noopt" to appear anywhere in
the builder name when checking if it's running on a noopt builder.
