runtime: introduce GOTRACEBACK=single, now the default
Abandon (but still support) the old numbering system.
GOTRACEBACK=none is old 0
GOTRACEBACK=single is the new behavior
GOTRACEBACK=all is old 1
GOTRACEBACK=system is old 2
GOTRACEBACK=crash is unchanged
See doc comment change in runtime1.go for details.
Filed #13107 to decide whether to change default back to GOTRACEBACK=all for Go 1.6 release.
If you run into programs where printing only the current goroutine omits
needed information, please add details in a comment on that issue.
Fixes #12366.
