Joe Sylve df2b2eb63d runtime: improve last ditch signal forwarding for Unix libraries
The current runtime attempts to forward signals generated by non-Go
code to the original signal handler.  If it can't call the original
handler directly, it currently attempts to re-raise the signal after
resetting the handler.  In this case, the original context is lost.

This fix prevents that problem by simply returning from the go signal
handler after resetting the original handler.  It only does this when
the original handler is the system default handler, which in all cases
is known to not recover.  The signal is not reset, so it is retriggered
and the original handler takes over with the proper context.

Fixes #14899

Go is the work of hundreds of contributors. We appreciate your help!

Binary Distribution Notes

If you have just untarred a binary Go distribution, you need to set the environment variable $GOROOT to the full path of the go directory (the one containing this file). You can omit the variable if you unpack it into /usr/local/go, or if you rebuild from sources by running all.bash (see doc/install-source.html). You should also add the Go binary directory $GOROOT/bin to your shell's path.

For example, if you extracted the tar file into $HOME/go, you might put the following in your .profile:

export GOROOT=$HOME/go
export PATH=$PATH:$GOROOT/bin

See https://golang.org/doc/install or doc/install.html for more details.
