net/http/httputil: always deep copy the Request.Header map in ReverseProxy

We used to do it sometimes as an optimization, but the optimization is
flawed: in all non-contrived cases we need to deep clone the map
anyway. So do it always, which both simplifies the code but also fixes
the X-Forward-For value leaking to the caller's Request, as well as
modifications from the optional Director func.

Fixes #18327

runtime: drain local runq when dedicated mark worker runs

When the dedicated mark worker runs, the scheduler won't run on that P
again until GC runs out of mark work. As a result, any goroutines in
that P's local run queue are stranded until another P steals them. In
a normally operating system this may take a long time, and in a 100%
busy system, the scheduler never attempts to steal from another P.

Fix this by draining the local run queue into the global run queue if
the dedicated mark worker has run for long enough. We don't do this
immediately upon scheduling the dedicated mark worker in order to
avoid destroying locality if the mark worker runs for a short time.
Instead, the scheduler delays draining the run queue until the mark
worker gets its first preemption request (and otherwise ignores the
preemption request).

Fixes #20011.

encoding/ascii85: make bigtest big again

ascii85_test.go contains a variable called bigtest that is used as
test data for TestDecoderBuffering and TestEncoderBuffering.  The
variable is initialised to a copy of the last element of the pairs
slice.  When the variable was first added the last element of this
slice contained a sizable test case, 342 encoded characters.  However,
https://golang.org/cl/5970078 added a new element to the end of the pairs
slice without updating bigtest.  As the new element contained only 1 byte
of encoded data bigtest became very small test.  This commit fixes the
problem by resetting bigtest to its original value and making its
initialisation independent of the layout of pairs.  All the unit tests
still pass.

syscall: use CLONE_VFORK safely

Currently, CLONE_VFORK is used without much regard to the stack. This
is dangerous, because anything the child does to the stack is visible
to the parent. For example, if the compiler were to reuse named stack
slots (which it currently doesn't do), it would be easy for the child
running in the same stack frame as the parent to corrupt local
variables that the parent then depended on. We're not sure of anything
specific going wrong in this code right now, but it is at best a
ticking time bomb.

CLONE_VFORK can only safely be used if we ensure the child does not
execute in any of the active stack frames of the parent. This commit
implements this by arranging for the parent to return immediately from
the frame the child will operate in, and for the child to never return
to the frame the parent will operate in.

Fixes #20732.

testing: harmonize handling of prefix-matched benchmarks

If you have BenchmarkX1 with sub-benchmark Y
and you have BenchmarkX2 with no sub-benchmarks,
then

go test -bench=X/Y

runs BenchmarkX1 once with b.N=1 (to find out about Y)
and then not again, because it has sub-benchmarks,
but arguably also because we're interested in Y.

In contrast, it runs BenchmarkX2 in full, even though clearly
that is not relevant to the match X/Y. We do have to run X2
once with b.N=1 to probe for having X2/Y, but we should not
run it with larger b.N.

cmd/compile: permit Unicode spaces in (expanded) package paths

This doesn't change the existing restriction with disallows

It simply permits packages to be under a directory name that

Verified manually that it works. This could use a test, but the
change is trivial. We also can't use the existing test framework
(under test/) because the way those tests are run with test/run.go,

(the compilation is local).

net: handle spurious netpoll wakeups in connect

In some cases the netpoll code can cause a spurious wakeup. This is
normally harmless, as the woken up code simply retries the operation.
However, for connect, the test we were using to see whether the
connect had succeeded (setsockopt(SO_ERROR)) was not reliable in the
case of a spurious wakeup. Change to using a reliable test (getpeername).
On Darwin we used a different technique: a second call to connect;
change Darwin to use getpeername as well.

Return the result of getpeername to avoid having to call it twice.

First, this is only working for "go1", so it could be confusing.

encoding/json: don't marshal unexported embedded fields of non struct type

Marshal must process unexported embedded fields of struct type,
looking for exported fields in those structs. However, it must
not process unexported embedded fields of non-struct type.

For example, consider:

    type t1 struct {
        X int
    }
    type t2 int
    type T struct {
        t1
        t2
    }

When considering T, Marshal must process t1 to find t1.X.
Marshal must not process t2, but it was. Fix that.
