App Engine even though is Linux, does not allow referencing the syscall package. Thus I reorganised the udp*.go files a little to make this work. As best I can the functionality is unchanged, and all this continues to compiles on darwin, linux, windows, plan9 and appengine. Namely: * Moved all Linux specific code from udp.go into udp_linux.go (e.g setUDPSocketOptions) * Deleted udp_plan9.go which was almost a copy of udp.go. * Added build tags to stop appengine using the linux build, and instead using the udp_other.go.
