discovery: pass pushop to _nowarnheads

Previously, we passed only enough information to _nowarnheads to perform the old
calculation. However, extensions may want to use more information in this
calculation. Now that pushop is extensible, extensions will often want access
to the additional fields they have added to the pushop, so pass that through.

Specifically, the remotenames extension will use this information to allow
pushing new heads that are bookmarked without requiring --force.

aren't changed), even if none of mode, size and timestamp of them
isn't changed on the filesystem (see also issue4583).
