leads to slightly incorrect error codes. The caller may get a:
errors.New("os: process already finished")

There is currently no way to ignore signals using the os/signal package.
It is possible to catch a signal and do nothing but this is not the same
as ignoring it. The new function Ignore allows a set of signals to be
ignored. The new function Reset allows the initial handlers for a set of
signals to be restored.
Fixes#5572

This is an alternative to http://golang.org/cl/4150,
and is motivated by a review comment on that CL.
testKillProcess() tries to build and run the Go equivalent
for "sleep 1". This doesn't work for testing cross compilers
since the Go compiler is not available on the targets. This
change embeds the "sleep 1" functionality within the "os.test"
binary itself.

Reverts https://golang.org/cl/119530044 (OS X 10.10 Yosemite beta
14A299l workaround), since it was fixed in the final Yosemite release.
I verified that the C program http://swtch.com/~rsc/readdirbug.c
passes on Yosemite.
Adds a new test to the os package too, to verify that reading a
regular file as a directory fails.
Fixes#9789 (ReadDir: no error if dirname is a file)

This change is an implementation of the signal
runtime and os/signal package on Plan 9.
Contrary to Unix, on Plan 9 a signal is called
a note and is represented by a string.
For this reason, the sigsend and signal_recv
functions had to be reimplemented specifically
for Plan 9.
In order to reuse most of the code and internal
interface of the os/signal package, the note
strings are mapped to integers.
Thanks to Russ Cox for the early review.

Since CL 3676, the TestMkdirAllAtSlash test
depends on syscall.EROFS, which isn't defined
on Plan 9.
This change works around this issue by
defining a system dependent isReadonlyError
function.

This is a followup to CL 3676.
Rather than silently returning from the test, a pass,
use the Skip facility to mark the test as skipped.

On some systems (e.g. ChromeOS), / is mounted read-only.
This results in error code syscall.EROFS, which I guess
is just as valid as syscall.EACCES for this test.

This change is a recreation of the CL written
by Nick Owens on http://golang.org/cl/150730043.
If the stat buffer is too short, the kernel
informs us by putting the 2-byte size in the
buffer, so we read that and try again.
This follows the same algorithm as /sys/src/libc/9sys/dirfstat.c.
Fixes#8781.
