Avoid spamming the GUI in multipv search

Browse Source 
Send the PV lines to GUI only once at the end of the
PV search loop or just in case of long searches.

We need to sync also sending of "currmove" info to
avoid sending info on current move without first
informing the GUI on the PV line we are searching on.

No functional change.
