The client code was using time.Now() (wall time) to determine whether
the cause of a non-nil error meant that a timeout had occured. But on
Windows, the clock used for timers (time.After, time.Sleep, etc) is
much more accurate than the time.Now clock, which doesn't update
often.
But it turns out that as of the recent https://golang.org/cl/32478 we
already have the answer available easily. It just wasn't in scope.
Instead of passing this information along by decorating the errors
(risky this late in Go 1.8, especially with #15935 unresolved), just
passing along the "didTimeout" func internally for now. We can remove
that later in Go 1.9 if we overhaul Transport errors.
Fixes#18287 (I hope)

Now that we try to handle qualifiers correctly (as of CL 33325), don't
strip them from a void* pointer. Otherwise we break a case like "const
void**", as the "const" qualifier is dropped and the resulting
"void**" triggers a warning from the C compiler.

The check for duplicate struct field tags introduced in CL 16704
triggers a panic when an anonymous struct field with a duplicate name
is encountered. For such a field, the names slice of the ast.Field is
nil but accessed regardless to generate the warning message.
Additionally, the check produces false positives for XML tags in some
cases:
- When fields are encoded as XML attributes, a warning is produced when
an attribute reuses a name previously used for an element.
Example:
type Foo struct {
First int `xml:"a"`
NoDup int `xml:"a,attr"` // warning about reuse of "a"
}
- When XMLName is used to set the name of the enclosing struct element,
it is treated as a regular struct field.
Example:
type Bar struct {
XMLName xml.Name `xml:"a"`
NoDup int `xml:"a"` // warning about reuse of "a"
}
This commit addresses all three issues. The panic is avoided by using
the type name instead of the field name for anonymous struct fields when
generating the warning message. An additional namespace for checking XML
attribute names separately from element names is introduced. Lastly,
fields named XMLName are excluded from the check for duplicate tags.

Change the openbsd runtime to use the current sys_kill and sys_thrkill
system calls.
Prior to OpenBSD 5.9 the sys_kill system call could be used with both
processes and threads. In OpenBSD 5.9 this functionality was split into
a sys_kill system call for processes (with a new syscall number) and a
sys_thrkill system call for threads. The original/legacy system call was
retained in OpenBSD 5.9 and OpenBSD 6.0, however has been removed and
will not exist in the upcoming OpenBSD 6.1 release.
Note: This change is needed to make Go work on OpenBSD 6.1 (to be
released in May 2017) and should be included in the Go 1.8 release.
This change also drops support for OpenBSD 5.8, which is already an
unsupported OpenBSD release.

The pclntable contains pointers to functions. If the function symbol
is exported in a plugin, and there is a matching symbol in the host
binary, then the pclntable of a plugin ends up pointing at the
function in the host module.
This doesn't work because the traceback code expects the pointer to
be in the same module space as the PC value.
So don't export functions that might overlap with the host binary.
This way the pointer stays in its module.

This rolls back https://golang.org/cl/27117 partly, softening it so it
only retries POST/PUT/DELETE etc requests where there's no Body (nil
or NoBody). This is a little useless, since most idempotent requests
have a body (except maybe DELETE), but it's late in the Go 1.8 release
cycle and I want to do the proper fix.
The proper fix will look like what we did for http2 and only retrying
the request if Request.GetBody is defined, and then creating a new request
for the next attempt. See https://golang.org/cl/33971 for the http2 fix.

The combination of two prior CLs can cause panics:
* CL/17873: make chained multiReader Read more efficient
* CL/28533: make MultiReader nil exhausted Readers for earlier GC
The first CL allows MultiReader to "inherit" another MultiReader's list of Readers
for efficiency reasons. This is problematic when combined with the
later CL since that can set prior Readers in that list to nil for GC reasons.
This causes panics when two MultiReaders are used together (even synchronously).
To fix this, rather than setting consumed Readers as nil, we set them with
a special eofReader that always returns EOF.
