Add -forceibdcomplete and use IBD to allow all-peer headers-sync.

Browse source 
This uses IsInitialBlockDownload to enable headers-fetching from
all peers (in addition to the existing recent-headers-tip check).
It also adds a hidden flag which allows you to force IBD to false,
enabling download from all peers.
