Old behavior: 10 consecutive EPIPE errors on any descriptor cause the
program to exit with a SIGPIPE signal.
New behavior: an EPIPE error on file descriptors 1 or 2 cause the
program to raise a SIGPIPE signal. If os/signal.Notify was not used to
catch SIGPIPE signals, this will cause the program to exit with SIGPIPE.
An EPIPE error on a file descriptor other than 1 or 2 will simply be
returned from Write.
Fixes#11845.
Update #9896.

This CL changes the source file information in the
standard library's .a files to say "$GOROOT/src/runtime/chan.go"
(with a literal "$GOROOT") instead of spelling out the actual directory.
The linker then substitutes the actual $GOROOT (or $GOROOT_FINAL)
as appropriate.
If people download a binary distribution to an alternate location,
following the instructions at https://golang.org/doc/install#install,
the code before this CL would end up with source paths pointing to
/usr/local/go no matter where the actual sources were.
Now the source paths for built binaries will point to the actual sources
(hopefully).
The source line information in distributed binaries is not affected:
those will still say /usr/local/go. But binaries people build themselves
(their own programs, not the go distribution programs) will be correct.
Fixing this path also fixes the lookup of the runtime-gdb.py file.
Fixes#5533.

Following the parallelization of some tests, a race condition can
occur in testcarchive, testshared and testcshared.
In some cases, it can result in the go env GOROOT command returning
corrupted data, which are then passed to a rm command.
Make the shell script more robust by not trusting the result of
the go env GOROOT command. It does not really fix the issue, but
at least prevent the entire repository to be deleted.

Rebuilding everything is the wrong default.
This CL updates the build script, but the builders may

rebuild using the test command (I doubt it).

Currently goroutineheader goes through some convolutions to *almost*
print the scan state of a G. However, the code path that would print
the scan state of the G refers to gStatusStrings where it almost
certainly meant to refer to gScanStatusStrings (which is unused), so
it winds up printing the regular status string without the scan state
either way. Furthermore, if the G is in _Gwaiting, we override the
status string and lose where this would indicate the scan state if it
worked.
This commit fixes this so the runtime prints the scan state. However,
rather than using a parallel list of status strings, this simply adds
a conditional print if the scan bit is set. This lets us remove the
string list, prints the scan state even in _Gwaiting, and lets us
strip off the scan bit at the beginning of the function, which
simplifies the rest of it.

If non-Go code calls sigaltstack before a signal is received, use
sigaltstack to determine the current signal stack and set the gsignal
stack to use it. This makes the Go runtime more robust in the face of
non-Go code. We still can't handle a disabled signal stack or a signal
triggered with SA_ONSTACK clear, but we now give clear errors for those
cases.

different type than the first argument. The second argument is the user

I base this on

not to mention actual testing.
While I was at it I removed a useless memclr in setsig, a relic of the C
