So far, virStreamInData() is effectively a wrapper over virFDStreamInData() which means it deals with files which can be rewind

(lseek()-ed) to whatever position we need. And in fact, that's what virFDStreamInData() does - it makes sure that the FD is left unchanged in terms of position in the file. Skipping the hole happens soon after - in daemonStreamHandleRead() when virStreamSendHole() is called. But this is about to change. Soon we will have another implementation where we won't be dealing with FDs but virNetMessage queue and it will be handy to pop message at the beginning of the queue. Implement and document this new behavior. Signed-off-by: Michal Privoznik <mpriv...@redhat.com>
