listen: Turn off CLIENT_MAX_WAIT_SECS
...
The idea behind this feature was to avoid the client thread in a listen
server getting stuck forever if the mirroring thread in the source died.
However, it breaks any sane implementation of max_Bps in that thread,
and there are lingering concerns over how it might operate under normal
conditions anyway.
Specifically, if iterating over the bitmap takes a long time, or even just
reading the requisite 8MB from the disc in order to send it, then the
5-second timeout could be hit, causing mirroring to fail unnecessarily.

Add a trivial read buffer to flexnbd-proxy.
...
Since the vast majority (something like 94% on boot) are sequential small
reads, and since network latency is a major factor in determining how fast the
exposed device appears to the client, it makes sense for us to try to minimise
the number of network requests where we safely can.
This patch implements the simplest possible read cache in flexnbd-proxy. When
it receives a read request, if it's a small request then flexnbd-proxy will
double the length of data requested. On receiving the data from the upstream
server, flexnbd-proxy will return the first half to the downstream as normal,
and stash the second half in a buffer. If the very next request is a read, and
the offset and length match those of what we have stored, that second request
will be satisfied from the buffer without going out over the network.
The cache is invalidated by any non-read request, or by a disconnection.
