On Windows, ERROR_MORE_DATA is not really an error. It means there's more data on the pipe, and it can be read in a subsequent call. Despite this, we've been treating as an error at the named pipe library level, and then working around it in consumers that need to allow those errors. This CL does a couple things: * Switches PipeConnection to ignore ERROR_MORE_DATA and return a successful read. * Remove all handling of ERROR_MORE_DATA in other parts of CrosVM. * Documents that Unix's version of ERROR_MORE_DATA (as implemented by us) is destructive and requires special handling.
