internal/lsp/lsprpc: partial integration of the jsonrpc_v2 library

Browse source 
Update the protocol package to allow wrapping the jsonrpc2 API, and add
wrappers for v1 and v2 of the API, so that we may switch between them.

Add simple bindings for the lsprpc package for jsonrpc2_v2 package, and
get them working well enough to pass a version TestClientLogging test.
This seemed like a reasonable checkpoint.

Also add some type safety to client closing: all LSP clients must
implement io.Closer.
