pjw fef9eaa9e4 x/tools/gopls: convert to the august, 2019 version of the LSP protocol
The latest version of the LSP protocol introduces a number of changes.
It is now possible to indicate partial results and progress. request.ts
had to construct some new types (at the end of tsclient.go and tsserver,go)
to avoid using a struct for a formal parameter type.  Also,
instead of using the same type for many RPCs, most RPCs now have their own
types.
