Subject: [PATCH 1/5] lib: tweak northbound gRPC default timeout
Don't let open sockets hang for too long. This will fix an issue where a
improperly coded client (e.g. socat) could exaust the amount of open
file descriptors.

Subject: [PATCH 5/5] lib: grpc: fix handling of "empty" yang type
- rather than coerce `const char *` to std:string&, just pass the
C ptr, as that's what is used anyway.
