Subject: [PATCH] src/server.c: increase max client buffer size to 1 MiB

Allows slow clients to better deal with large amounts of events
coming in from labwc like from high refresh rate mice. Without
this patch, the client is likely to get disconnected because the
labwc side client write buffer is full.
