- require borrows <= deposits, even if vaults have more tokens
- change min_vault_to_deposits_ratio to be about max utilization
Reviewed and audited as part of the v0.21.1 release, original

Previously, freeing would be impossible if a canceling fill or out event
was already in-flight - then the order would no longer be on the
orderbook.
Now, FillEvent and OutEvent store the order id and can check if the open
order slot on the account has been reused already. That allows canceling
orders to always free up the user slot immediately.
- since there's no borrowing or asset weight, don't put staleness or
confidence restrictions on the oracle
- disable the tcs fees, they are not enabled anywhere yet
- limit deposits (via deposit, flash loan, tcs)
- limit potential deposits via openbook settle
by restricting placable orders via potential_serum_tokens
- introduce Serum3PlaceOrderV2 for this purpose
- account for new limits in liquidator, max_swap
- track min bid, max ask
- track maximal token outflow from oo
- add serum3_place_order_v2 with mutable receiver bank
- placing openbook orders is restricted to a certain distance from the
oracle

- token_edit can set it up to gradually scale to new target values
- security admin can abort an ongoing change via token_edit
- all health computations are now time dependent and get the weight
based on it
- when the change is done, the keeper "cleans up" and moves the new
values into the default fields
- Only ever give an incentive when pnl is at least 1% of the position
value. That way large positions (like $100k in SOL-PERP) don't get
settled on 0.1% price fluctuations. The price now needs to change by
1% for settlement to occur.
- For low health incentives, cap the percentual incentive at 2x the flat
settle fee. We want to give the settler incentive to use these first,
but the settler doesn't take on risk, so the reward doesn't need to be
large.
Many instructions now return PreparedInstructions instead of a direct
Instruction or Vec<Instruction>. That way they can keep track of the
expected cu cost of the instructions for the compute limit instruction
that gets added once all instructions are made.
