sideband: report unhandled incomplete sideband messages as bugs
It was pretty tricky to verify that incomplete sideband messages are
handled correctly by the `recv_sideband()`/`demultiplex_sideband()`
code: they have to be flushed out at the end of the loop in
`recv_sideband()`, but the actual flushing is done by the
`demultiplex_sideband()` function (which therefore has to know somehow
that the loop will be done after it returns).
To catch future bugs where incomplete sideband messages might not be
shown by mistake, let's catch that condition and report a bug.
