[Rd] serial connection patch

[Matt Shotwell]

Oh, I just put that there for the bit about "WITHOUT ANY WARRANTY" :). I
am satisfied with GPLv2 and have updated the license notice to reflect a
change from GPLv3 to GPLv2 or later.

A copyright transfer gives some legal clarification, but is only really required in case the R Foundation wants to (dual-) relicense under a GPL incompatible license, or need to be able to legally defend users' code against infringement. The former is highly unlikely, and it would require major disentanglement in other areas anyway, and I don't see contributions of this order of magnitude as a target of legal dispute either.
