TestSignalTrace can take a bit longer to run on some
ppc64{,le} machines. I was only able to reproduce the
timeout reliably on a POWER8/ppc64le ubuntu 16.04 host.
Bump the timeout to 5 seconds. This should be more than
sufficient for a test which occasionally takes a bit
longer to run on these builders.

If we're testing through dist, we're testing the implementation of Go,
so we're interested in any package failing with potential runtime
issues. In these cases, we'd like to have as much relevant detail as
possible, but currently runtime stack frames and goroutines are
suppressed due to the default GOTRACEBACK setting.
So, try to set GOTRACEBACK to system if it's unset. Check if it's unset
first so we don't override the user asking for a lower or higher level.
This change was brought up in the context of #45916, since there's an
apparent deadlock (or something!) in the runtime that appears when
running other code, but it's difficult to see exactly where it's
blocked. However, this change is very generally useful.
This change also runs scripted tests with GOTRACEBACK=system, upgrading
from GOTRACEBACK=all. Often, script tests can trigger failures deep in
the runtime in interesting ways because they start many individual Go
processes, so being able to identify points of interest in the runtime
is quite useful.
For #45916.

At this time, the golang.org/s/release process arranges such that the
api/go1.n.txt file is created when a Go 1.N Beta 1 release is being cut.
The API check is currently configured so that tests don't fail visibly
even if api/go1.n.txt becomes a subset of the actual API additions in
the upcoming Go 1.N release as long as 'go version' has "devel" in it.
The first time that 'go version' output drops the "devel" substring
during testing is after the release-branch.go1.N branch is created
as part of the process to cut a Go 1.N Release Candidate 1 release.
The month or so between Beta 1 and RC 1 is well into the freeze and
deliberate API changes are rare and very intentional. There seems to
be agreement that it's healthy to make the API check stricter during
that time period. Doing so will ensure that api/go1.n.txt cannot get
stale after creation without anyone noticing, and may catch CLs that
don't have the intended diff on the API.
This CL changes behavior to be simple and clear: from the moment
an api/go1.n.txt file corresponding to the current Go version in
development is added to the tree, silent API additions stop being
permitted.
This CL also moves the magical "override the value of -allow_new flag
if runtime.Version() contains 'devel' string" behavior from cmd/api
command to the run.go script that calls it, making the CLI of cmd/api
itself less surprising.

When creating programs with large text sections on ppc64le,
trampolines are needed for calls that are too far; however
they are not created if the code is generated such that the TOC
register r2 is initialized and maintained in the code because
then the external linker can create the trampolines. Previously
the function DynlinkingGo was used to determine this but in the
case where plugins are used, this could return true even though
r2 is not valid.
To fix this problem I've added a new function r2Valid which returns

It seems like getgrouplist is supported since Solaris 11.3 (released in
2016):
https://docs.oracle.com/cd/E86824_01/html/E54766/getgrouplist-3c.html
Use it to implement (*User).GroupIds on solaris, like on other Unix
platforms.
Unfortunately it looks like getgrouplist was added to illumos only
fairly recently, see
f2c438c505
Thus, don't use it on GOOS=illumos for now.

Previously calling fmt.Sprintf("%#v", t) on a time.Time value would
yield a result like:
time.Time{wall:0x0, ext:63724924180, loc:(*time.Location)(nil)}
which does not compile when embedded in a Go program, and does not
tell you what value is represented at a glance.
This change adds a GoString method that returns much more legible
output:
"time.Date(2009, time.February, 5, 5, 0, 57, 12345600, time.UTC)"
which gives you more information about the time.Time and also can be
usefully embedded in a Go program without additional work.
Update Quote() to hex escape non-ASCII characters (copying logic
from strconv), which makes it safer to embed them in the output of
GoString().
Fixes#39034.

Currently, when ABI wrappers are used, we don't use ABI aliases.
One exception is shared linkage. When loading a shared library, if
a symbol has only one ABI, and the name is not mangled, we don't
know what ABI it is, so we have to use ABI aliases.
This CL makes it always mangle ABIInternal function name in shared
linkage, so we know what ABI to choose when loading a shared
library. And we now can fully stop using ABI aliases when ABI
wrappers are used.

This is a port of CL 315729 to go/types, adjusted for the slightly
different test set-up in go/types.
Added a TODO to reconcile these differences.
