- Rename to perp_liq_base_or_positive_pnl and perp_liq_negative_pnl_or_bankruptcy
- Deal with situations where overall asset weight is zero and base position reduction
would not improve liqee health
- Add ability for liqors to take over positive unsettled pnl if that improves liqee health
This replaces the previous distinction between trusted and untrusted
markets, they are equivalent to setting the asset weights to 1 or 0
instead.
This way, we can weigh positive pnl in the trusted case at less than 1
which is more correct from a risk point of view and allows for more
flexibility when it comes to liquidation.
