add go.mod and go.sum

[JAicewizard]

add support for go modules.

We think we should wait until go modules are more official before we investigate further.

[jkellz-dev]

Modules is pretty official at this point. Any chance this is being revisited?

[mimoo]

yep, can confirm, totally broken with go modules

[hyphenlee]

any update for go modules?

[ergoz]

i have a pain with paths for gogofast and etc at this moment with go modules

On windows it will be something like this to make it work:

protoc -I=./protobuf \
    -I=. \
    -I=$GOPATH/src \
    -I=$GOPATH/pkg/mod/github.com/gogo/protobuf@v1.3.0 \
    --gogofast_out=./structs/gogofast \
    gogo.proto

this path i should fix every time gogo release updates

It would be amazing if this were go module aware and prevent me from having to find the right module/version path to include.

@ergoz My work around was to use go list -f '{{ .Dir }}' -m github.com/gogo/protobuf to determine the path to the right version of gogo/protobuf.
