common/options: Set osd_client_message_cap to 256.

This seems like a reasonable default value based on testing results here:

Eventually we may want to rethink how the throttles and even how flow control
works, but this at least gives us some basic limits now ( a little higher than
the old value of 100 that we used for many years).
