godoc: display "go vet" errors before the output of a program

This change adds an option to run "go vet" for the playground program
and display errors before any output. To enable this, the playground
function has to be supplied with opts.enableVet set to true.
Vet check is performed only for succesfully run programs,
meaning that the "/compile" endpoint returned no errors.

This change highlights lines printed to stderr as errors (in red).

There is a corresponding change for the Playground: CL 100776.

Go Tools

This subrepository holds the source for various packages and tools that support the Go programming language.

Some of the tools, godoc and vet for example, are included in binary Go distributions.

Others, including the Go guru and the test coverage tool, can be fetched with go get.

Packages include a type-checker for Go and an implementation of the Static Single Assignment form (SSA) representation for Go programs.

Download/Install

The easiest way to install is to run go get -u golang.org/x/tools/.... You can also manually git clone the repository to $GOPATH/src/golang.org/x/tools.
