Fixes an issue where Response.Write writes out a Content-Length: -1

ContentLength was not previously set.

This was encountered when using httputil.DumpResponse
to write out the response from a server that responded to a PUT
request with no Content-Length header. The dumped output is
thus invalid.

Also clarifies the usage of Source and Addr fields.

d12b532265 time: use longer delta duration for TestAfterQueueing retries
The TestAfterQueueing test is inherently flaky because it relies on
independent kernel threads being scheduled within the "delta" duration
of each other.  Normally, delta is 100ms but during "short" testing,
it's reduced to 20ms.

On at least OpenBSD, the CPU scheduler operates in 10ms time slices,
so high system load (e.g., from running multiple Go unit tests in
parallel, as happens during all.bash) can occasionally cause >20ms
scheduling delays and result in test flaking.  This manifests as issue
9903, which is the currently the most common OpenBSD flake.

To mitigate this delay, only reduce the delta duration to 20ms for the
first attempt during short testing.  If this fails and the test is
reattempted, subsequent attempts instead use a full 100ms delta.

Fixes #9903.

4b78c9575d runtime: print stack of G during a signal
Sequence of operations:
- Go code does a systemstack call
- during the systemstack call, receive a signal
- signal requests a traceback of all goroutines

The orignal G is still marked as _Grunning, so the traceback code
refuses to print its stack.

Fix by allowing traceback of Gs whose caller is on the same M as G is.
G can't be modifying its stack if that is the case.

Fixes #10546

4d1ab2d8d1 runtime: re-enable TestNewProc0 on android/arm and fix heap corruption
The problem is not actually specific to android/arm. Linux/ARM's
runtime.clone set the stack pointer to child_stk-4 before calling
the fn. And then when fn returns, it tries to write to 4(R13) to
provide argument for runtime.exit, which is just beyond the allocated
child stack, and thus it will corrupt the heap randomly or trigger
segfault if that memory happens to be unmapped.

While we're at here, shorten the test polling interval to 0.1s to
speed up the test (it was only checking at 1s interval, which means
the test takes at least 1s).

Fixes #10548.

c26fc88d56 runtime/pprof: write heap statistics to heap profile always
The heap statistics were only written if asked for a profile with debug > 0,
but that also prints a stack trace for each profile line, which is comparatively
much noisier. The statistics are short enough and separate enough
(they only appear at the end) and useful enough that we can print them
always.

This means that people using -test.memprofile in tests will get a memory
profile with statistics included now. Pprof won't care, but if people care to
look, the numbers will be there.

This avoids the need for hacks like using -memprofilerate=1 to find
the number of allocations.

c526f3ac10 runtime: tail call into memeq/cmp body implementations
There's no need to call/ret to the body implementation.
It can write the result to the right place.  Just jump to
it and have it return to our caller.

Old:
  call body implementation
  compute result
  put result in a register
  return
  write register to result location
  return

New:
  load address of result location into a register
  jump to body implementation
  compute result
  write result to passed-in address
  return

It's a bit tricky on 386 because there is no free register
with which to pass the result location.  Free up a register
by keeping around blen-alen instead of both alen and blen.

d942737f8a crypto/x509: allow parsing of certificates with unknown critical extensions.
Previously, unknown critical extensions were a parse error. However, for
some cases one wishes to parse and use a certificate that may contain
these extensions. For example, when using a certificate in a TLS server:
it's the client's concern whether it understands the critical extensions
but the server still wishes to parse SNI values out of the certificate
etc.

This change moves the rejection of unknown critical extensions from
ParseCertificate to Certificate.Verify. The former will now record the
OIDs of unknown critical extensions in the Certificate and the latter
will fail to verify certificates with them. If a user of this package
wishes to handle any unknown critical extensions themselves, they can
extract the extensions from Certificate.Extensions, process them and
remove known OIDs from Certificate.UnknownCriticalExtensions.

Fixes #10459

63caec5dee runtime: eliminate one heapBitsForObject from scanobject
scanobject with ptrmask!=nil is only ever called with the base
pointer of a heap object. Currently, scanobject calls
heapBitsForObject, which goes to a great deal of trouble to check
that the pointer points into the heap and to find the base of the
object it points to, both of which are completely unnecessary in
this case.

Replace this call to heapBitsForObject with much simpler logic to
fetch the span and compute the heap bits.

2a73559023 cmd/internal/gc: emit typedmemmove write barrier from sgen
Emitting it here instead of rewriting the tree earlier sets us up
to generate an inline check, like we do for single pointers.
But even without the inline check, generating at this level lets
us generate significantly more efficient code, probably due to
having fewer temporaries and less complex high-level code
for the compiler to churn through.

Revcomp is worse, almost certainly due to register pressure.

653d56075d cmd/internal/gc: inline writeBarrierEnabled check before calling writebarrierptr
I believe the benchmarks that get slower are under register pressure,
and not making the call unconditionally makes the pressure worse,
and the register allocator doesn't do a great job. But part of the point
of this sequence is to get the write barriers out of the way so I can work
on the register allocator, so that's okay.

2050f57141 runtime: change unused argument in fat write barriers from pointer to scalar
The argument is unused, only present for alignment of the
following argument. The compiler today always passes a zero
but I'd rather not write anything there during the call sequence,
so mark it as a scalar so the garbage collector won't look at it.

As expected, no significant performance change.

6c328efc4c cmd/internal/gc: accept comma-separated list of name=value for -d
This should obviously have no performance impact.
Listing numbers just as a sanity check for the benchmark
comparison program: it should (and does) find nothing
to report.
