This change separates the different behaviors of server.go by the categories defined in the spec. This allows us to differentiate more easily between the language features and the text synchronization code. I also renamed the "Symbols" function to "Symbol", which fits with the specification (https://microsoft.github.io/language-server-protocol/specification#workspace_symbol), and makes clearer the distinction between DocumentSymbols and Symbol.
