socket-handler: Use a global backlog buffer instead of per-client

Currently, we keep a backlog buffer for each connected client. This is a
waste, as it's storing the same data, just at different offsets.

This change uses a global buffer for the client backlog, with each
client tracking its current position in this buffer. We just make this
fixed-size, rather than trying to dynamically allocate.
