3db848abec mcp: implement a concurrency model for calls
Implement the concurrency model described in #26: notifications are
synchronous, but calls are asynchronous (except for 'initialize'). To
achieve this, implement jsonrpc2.Async(ctx) to signal asynchronous
handling. This is simpler to use than returning ErrAsyncResponse and
calling Respond, and since this is an internal detail we don't need to
worry too much about whether it's idiomatic.

Add tests that verify both features, for both client and server.

Also:
- replace req.ID.IsValid with req.IsCall
- remove the methodHandler type as we can just use MethodHandler

Fixes #26

47e1b0be9d x/tools: modernize interface{} -> any
Produced with a patched version of modernize containing only
the efaceany pass:

$ go run ./gopls/internal/analysis/modernize/cmd/modernize/main.go -test -fix ./... ./gopls/...

This is very safe and forms the bulk of the modernize diff,
isolating the other changes for ease of review.

280ef9a723 internal/lsp/lsprpc: update binder tests to handle forwarding
Update the new binder tests to run both with a standalone server, and
with a forwarding chain.

Make a few superficial improvements along the way as well.

0c89f898b7 internal/jsonrpc2_v2: initialize async before binding
The lsprpc package needs to wait on the newly bound connection to
perform some tear-down, so it must be safe to call conn.Wait from Bind.

Achieve this by switching async from an init pattern to a constructor.
This means moving async fields to pointers, but since they weren't safe
to use prior to initialization anyway this feels correct.

b619c1cc78 internal/lsp/lsprpc: partial integration of the jsonrpc_v2 library
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.
