Always allow getheaders from whitelisted peers

laanwj · laanwj · commit 40b77d450dff · 2015-11-09T14:28:49.000+01:00
Process `getheaders` messages from whitelisted peers even if we are in initial block download. Whitelisted peers can always use a node as a block source. Also log a debug message when the request is ignored, for troubleshooting. Fixes #6971.
