all: make copyright headers consistent with one space after period This is a subset of https://golang.org/cl/20022 with only the copyright header lines, so the next CL will be smaller and more reviewable. Go policy has been single space after periods in comments for some time. The copyright header template at: https://golang.org/doc/contribute.html#copyright also uses a single space. Make them all consistent.

[dev.cc] cmd/internal/obj: convert liblink C to Go This CL adds the real cmd/internal/obj packages. Collectively they correspond to the liblink library. The conversion was done using rsc.io/c2go's run script at rsc.io/c2go repo version 706fac7. This is not the final conversion, just the first working draft. There will be more updates, but this works well enough to use with go tool objwriter and pass all.bash.

cmd/internal/obj, cmd/link, runtime: increase stack limit to accommodate larger frames on ppc64x Larger stack frames mean nosplit functions use more stack and so the limit needs to increase. The change to test/nosplit.go is a bit ugly but I can't really think of a way to make it nicer.
