a7dcfa6133 cmd/internal/objfile: make lookupFunc an alias type
In the x/arch repo, CL 45098 introduced SymLookup type, replacing
the unnamed function type for lookup functions. This affects the
signature of x86asm.GoSyntax. In particular, it cannot convert
one named type, namely lookupFunc, to the other without an
explicit cast. Make lookupFunc unnamed to fix.

9ec0c7abe1 archive/tar: use placeholder name for global PAX records
Several usages of tar (reasonably) just use the Header.FileInfo
to determine the type of the header. However, the os.FileMode type
is not expressive enough to represent "files" that are not files
at all, but some form of metadata.

Thus, Header{Typeflag: TypeXGlobalHeader}.FileInfo().Mode().IsRegular()
reports true, even though the expected result may have been false.

To reduce (not eliminate) the possibility of failure for such usages,
use the placeholder filename from the global PAX headers.
Thus, in the event the user did not handle special "meta" headers
specifically, they will just be written to disk as a regular file.

As an example use case, the "git archive --format=tgz" command produces
an archive where the first "file" is a global PAX header with the
name "global_pax_header". For users that do not explicitly check
the Header.Typeflag field to ignore such headers, they may end up
extracting a file named "global_pax_header". While it is a bogus file,
it at least does not stop the extraction process.

d85a3535fe archive/zip: preserve old FileHeader.ModTime behavior
In order to avoid a regression where the date of the ModTime method
changed behavior, simply preserve the old behavior of determining
the date based on the legacy fields.

This ensures that anyone relying on ModTime before Go1.10 will have
the exact same behavior as before.
New users should use FileHeader.Modified instead.

We keep the UTC coersion logic in SetModTime since some users
manually compute timezone offsets in order to have precise control
over the MS-DOS time field.

18ae4c834b net/http: panic on invalid WriteHeader status code
Panic if an http Handler does:

    rw.WriteHeader(0)

... or other invalid values. (for a forgiving range of valid)

I previously made it kinda work in https://golang.org/cl/19130 but
there's no good way to fake it in HTTP/2, and we want HTTP/1 and
HTTP/2 behavior to be the same, regardless of what programs do.
Currently HTTP/2 omitted the :status header altogether, which was a
protocol violation. In fixing that, I found CL 19130 added a test
about bogus WriteHeader values with the comment:

  // This might change at some point, but not yet in Go 1.6.

This now changes. Time to be strict.

1c69384da4 net/textproto: reject all headers with a leading space
Previously, golang.org/cl/75350 updated ReadMIMEHeader to ignore the
first header line when it begins with a leading space, as in the
following example:

GET / HTTP/1.1
  Host: foo.com
Accept-Encoding: gzip

However, golang.org/cl/75350 changed ReadMIMEHeader's behavior for the
following example: before the CL it returned an error, but after the
CL it ignored the first line.

GET / HTTP/1.1
  Host foo.com
Accept-Encoding: gzip

This change updates ReadMIMEHeader to always fail when the first header
line starts with a space. During the discussion for golang.org/cl/75350,
we realized we had three competing needs:

1. HTTP clients should accept malformed response headers when possible
   (ignoring the malformed lines).

2. HTTP servers should reject all malformed request headers.

3. The net/textproto package is used by multiple protocols (most notably,
   HTTP and SMTP) which have slightly different parsing semantics. This
   complicates changes to net/textproto.

We weren't sure how to best fix net/textproto without an API change, but
it is too late for API changes in Go 1.10. We decided to ignore initial
lines that begin with spaces, thinking that would have the least impact on
existing users -- malformed headers would continue to parse, but the
initial lines would be ignored. Instead, golang.org/cl/75350 actually
changed ReadMIMEHeader to succeed in cases where it previously failed
(as in the above example).

Reconsidering the above two examples, there does not seem to be a good
argument to silently ignore ` Host: foo.com` but fail on ` Host foo.com`.
Hence, this change fails for *all* headers where the initial line begins
with a space.

3c7e491ba8 go/types: add debugging code to detect use of incomplete interfaces
The comment for phase 2 of checker.interfaceType (typexpr.go:517)
requires that embedded interfaces be complete for correctness of
the algorithm.

Yet, the very next comment (typexpr.go:530) states that underlying
embedded interfaces may in fact be incomplete.

This is in fact the case and the underlying bug in issue #18395.

This change makes sure that new interface types are marked complete
when finished (per the implicit definition in Interface.Complete,
type.go:302). It also adds a check, enabled in debug mode only, to
detect the use of incomplete embedded interfaces during construction
of a new interface. In debug mode, this check fails for the testcase
in the issue (and several others).

This change has no noticeable impact with debug mode disabled.

For #18395.

802a8f88a3 math/cmplx: use signed zero to correct branch cuts
Branch cuts for the elementary complex functions along real or imaginary axes
should be resolved in floating point calculations by one-sided continuity with
signed zero as described in:

"Branch Cuts for Complex Elementary Functions or Much Ado About Nothing's Sign Bit"
W. Kahan

Available at: https://people.freebsd.org/~das/kahan86branch.pdf

And as described in the C99 standard which is claimed as the original cephes source.

Sqrt did not return the correct branch when imag(x) == 0. The branch is now
determined by sign(imag(x)).  This incorrect branch choice was affecting the behavior
of the Trigonometric/Hyperbolic functions that use Sqrt in intermediate calculations.

Asin, Asinh and Atan had spurious domain checks, whereas the functions should be valid
over the whole complex plane with appropriate branch cuts.

Fixes #6888

be589f8d2b runtime: fix final stack split in exitsyscall
exitsyscall should be recursively nosplit, but we don't have a way to
annotate that right now (see #21314). There's exactly one remaining
place where this is violated right now: exitsyscall -> casgstatus ->
print. The other prints in casgstatus are wrapped in systemstack
calls. This fixes the remaining print.

Updates #21431 (in theory could fix it, but that would just indicate
that we have a different G status-related crash and we've *never* seen
that failure on the dashboard.)
