internal/lsp: introduce snippet builder object

*snippet.Builder helps you construct lsp completion snippet strings.
It handles escaping for you, and it gives a convenient interface for
writing nested placeholders.

Note that the builder does not support snippet "variables" or
associated features. They add a lot of complexity and don't seem very
useful at this point (plus they aren't supported in many editors).

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.
