Switch the command line client, and its tests, away from the hardcoded
30-second timeout and to a newly-added custom request.
Inconveniently for us, the jsonrpc2 package only serializes requests,
not replies. (Notifications are requests for this purpose.) So, for a
flow like this:
diagnoseFiles -->
<-- publishDiagnostics
<-- publishDiagnostics
diagnoseFiles <-- (reply)
...there's actually no guarantee that the incoming requests will be
processed before the reply comes in -- it gets to jump the
serialization. The only way to guarantee previous notifications have
been processed is to send another request. I didn't feel like adding
nonstandard notification support, so I just send a fake diagnostic.
Error handling for untyped JSON is hideous so for now we just panic.
Nobody else should be calling these, or if they do it's at their own
risk.
