Hana Kim 6d0d39b2ca bind: format generated go code before comparing with golden files
bind_test.go compares the generated Go files against golden files
checked in the repository. The bind package formats some of the
generated Go files, so any changes in the go formatter can break
the tests.

This change makes the test more robust by applying formatting based
on the currently used go version. Since a golden file often
includes multiple go files generated by the bind, the `gofmt`
function splits the golden file using the gobindPreamble marker
and then run format.Source for each chunk. In order to ease the
golden file splitting, this CL also moves the gobindPreamble
to the beginning of each generated file consistently.

It turned out bind omits formatting for some go files (generated
for reverse binding). That needs to be fixed but it is a much
bigger fix. Thus, in this CL, we apply the formatting on the
bind's output as well.

This CL also updates the gobindPreamble to follow the style guide
for generated code. https://golang.org/s/generatedcode

Fixes golang/go#34619
