There are some basic tests in the packages implementing the hashes,
but this one is meant to be comprehensive for the standard library
as a whole.
Most importantly, it locks in the current representations and makes
sure that they do not change from release to release (and also, as a
result, that future releases can parse the representations generated
by older releases).
The crypto/* MarshalBinary implementations are being changed
in this CL to write only d.x[:d.nx] to the encoding, with zeros for
the remainder of the slice d.x[d.nx:]. The old encoding wrote the
whole d.x, but that exposed an internal detail: whether d.x is
cleared after a full buffer is accumulated, and also whether d.x was
used at all for previous blocks (consider 1-byte writes vs 1024-byte writes).
The new encoding writes only what the decoder needs to know,
nothing more.
In fact the old encodings were arguably also a security hole,
because they exposed data written even before the most recent
call to the Reset method, data that clearly has no impact on the
current hash and clearly should not be exposed. The leakage
is clearly visible in the old crypto/sha1 golden test tables also
being modified in this CL.

This change updates runtime.semasleep to no longer call

relative to the monotonic clock, so the nanotime is never called.
(This requires updating to a newer version of the lwp_park system
call, which is safe, because Go 1.10 will require the unreleased
NetBSD 8+ anyway)
Additionally, this change makes the nanotime function use the
monotonic clock for netbsd/arm, which was forgotten from
https://golang.org/cl/81135 which updated netbsd/amd64 and netbsd/386.
Because semasleep previously depended on nanotime, the past few days

The full truth seems too complicated to write in this method's doc, so
I'm going with a simple half truth.
The full truth is that Fd returns the descriptor in blocking mode,
because that is historically how it worked, and existing programs
would be surprised if the descriptor is suddenly non-blocking. On Unix
systems whether a file is non-blocking or not is a property of the
underlying file description, not of a particular file descriptor, so
changing the returned descriptor to blocking mode also changes the
existing File to blocking mode. Blocking mode works fine, althoug I/O
operations now take up a thread. SetDeadline and friends rely on the
runtime poller, and the runtime poller only works if the descriptor is
non-blocking. So it's correct that calling Fd disables SetDeadline.
The other half of the truth is that if the program is willing to work
with a non-blocking descriptor, it could call
syscall.SetNonblock(descriptor, true) to change the descriptor, and
the original File, to non-blocking mode. At that point SetDeadline
would start working again. I tried to write that in a way that is
short and comprehensible but failed. Since deadlines mostly work on
pipes, and there isn't much reason to call Fd on a pipe, and few
people use SetDeadline, I decided to punt.

The number of threads in syscall presented by execution tracer's
trace view includes not only the threads calling system calls on behalf
of user created goroutines, but also those running on behalf of system
goroutines.
When the number of such system goroutines was small, the graph was
useful when examining where a program was saturating the CPU.
But as more and more system goroutines are invloved the graph became
less useful for the purpose - for example, after golang.org/cl/34784,
the timer goroutines dominate in the graph with large P
because the runtime creates per-P timer goroutines.
This change excludes the threads in syscall on behalf of runtime (system
goroutines) from the visualization. Alternatively, I could visualize the
count of such threads in a separate counter but in the same graph.
Given that many other debug endpoints (e.g. /debug/pprof/goroutine) hide
the system goroutines, including them in the same graph can confuse users.

Currently, when we minit on a thread that already has an alternate
signal stack (e.g., because the M was an extram being used for a cgo
callback, or to handle a signal on a C thread, or because the
platform's libc always allocates a signal stack like on Android), we
simply drop the Go-allocated gsignal stack on the floor.
This is a problem for Ms on the extram list because those Ms may later
be reused for a different thread that may not have its own alternate
signal stack. On tip, this manifests as a crash in sigaltstack because
we clear the gsignal stack bounds in unminit and later try to use
those cleared bounds when we re-minit that M. On 1.9 and earlier, we
didn't clear the bounds, so this manifests as running more than one
signal handler on the same signal stack, which could lead to arbitrary
memory corruption.
This CL fixes this problem by saving the Go-allocated gsignal stack in
a new field in the m struct when overwriting it with a system-provided
signal stack, and then restoring the original gsignal stack in
unminit.
This CL is designed to be easy to back-port to 1.9. It won't quite
cherry-pick cleanly, but it should be sufficient to simply ignore the
change in mexit (which didn't exist in 1.9).
