- 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
Which applies to the in token amount of swaps only.
Charging a deposit fee on flash loans was a bad idea:
- It incentivizes flash loan users to make the deposit a separate
instruction, defeating the purpose.
- For swaps, it makes traders pay a loan origination fee in in-token and
a deposit fee in out-token, leading to more complex bookkeeping and ui
display.
Instead, charge a fee on the in-token for all flash loans explicitly
marked as swaps only.
* Serum3 open orders: Fix health overestimation (#716)
When bids or asks crossed the oracle price, the serum3 health would be
overestimated before.
The health code has no access to the open order quantites or prices and
used to assume all orders are at oracle price.
Now we track an account's max bid and min ask in each market and use that
as a worst-case price. The tracking isn't perfect for technical reasons
(compute cost, no notifications on fill) but produces an upper bound on
bids (lower bound on asks) that is sufficient to make health not
overestimate.
The tracked price is reset every time the serum3 open orders on a book
side are completely cleared.

- The AccountExpand instruction can now shrink accounts by reducing
the number of token/perp/serum/tcs/perp oo slots.
- A new AccountSizeMigration instruction can permissionlessly shrink
accounts that are too large and migrate them to the v3 layout.
- Rename the new "swap fee" to "deposit fee" and let it apply to all
deposits, not just for Swap-type flash loans.
- But don't apply it to withdrawals (effectively giving rebates!)

Result of audit feedback
Tcs orders always store prices in a fixed "sell per buy" style, but users
can create them in either price direction. When they look at them later,
the ui needs to know what their preferred style is for this order.
- Update in_use_count to u16
- Pass banks to TCS cancel instruction
- Increase the in_use_count when a tcs is created and decrease on
trigger/cancel
(cherry picked from commit 5dd5c507f2)
To have more precision when storing user supplied prices and ensure that
the rounding that will occur will be tiny compared to the user-provided
precision.
Users can request token swaps to happen when the oracle price
is within a price band. Once the price is right, an executor can
trigger the swap. The executors are rewarded with a premium
over the oracle price.
This allows limit and stop loss orders on arbitrary spot pairs.
The PR comes with basic ts support and adjustments to the liquidator,
to execute available token conditional swaps.

This changes perp market margining to no longer assume all pnl is in USD
while settlement is in USDC. Instead, a configurable settle token is used for
pnl and settlement, defaulting to USDC.
There is no difference while the USDC price is forced to $1 and the init and liab
weights are 1. But with this patch, it becomes possible to change that.
For now it is not recommended to use a token other than USDC or USDT (or
another USD targeting stable token) for perp settlement.
The patch also updates all insurance vault use to be aware that the insurance
fund is not in USD but in USDC and apply the USDC price before payouts.
To do this, the previous PerpLiqNegativePnlOrBankruptcy was replaced by
a new PerpLiqNegativePnlOrBankruptcyV2 instruction.
