e097918484As described in #272, there is really no reason for transports to be closed structs with constructors, since their state must be established by a call to Connect. Making them open structs simplifies their APIs, and means that all transports can be extended in the future: we don't have to create empty Options structs just for the purpose of future compatibility. For now, the related constructors and options structs are simply deprecated (with go:fix directives where possible). A future CL will remove them prior to the v1.0.0 release. For #272
