Reject oversized messages on the sender side, keeping the
receiver side rejection intact. This should provide minimal
low-level plumbing for clients to attempt application level
corrective actions on the requestor side, if the high-level
protocol is designed with this in mind.

Use a dedicated, grpc Status-compatible error to wrap the
unique grpc status code, the size of the rejected message
and the maximum allowed size when a message is rejected
due to size limitations by the sending side.

Fix a race where an asynchronous server.Serve() invoked in a
a goroutine races with an almost immediate server.Shutdown().
If Shutdown() finishes its locked closing of listeners before
Serve() gets around to add the new one, Serve will sit stuck
forever in l.Accept(), unless the caller closes the listener
in addition to Shutdown().

This is probably almost impossible to trigger in real life,
but some of the unit tests, which run the server and client
in the same process, occasionally do trigger this. Then, if
the test tries to verify a final ErrServerClosed error from
Serve() after Shutdown() it gets stuck forever.

Implement configurable limits for the maximum accepted message
size of the wire protocol. The default limit can be overridden
using the WithClientWireMessageLimit() option for clients and
using the WithServerWireMessageLimit() option for servers. Add
exported constants for the minimum, maximum and default limits.

Adjust unit test to accomodate for altered internal interfaces.
Add unit tests to exercise the new message size limit options.
