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.

* Vendor `fixed` crate to have checked math in release mode
* remove all cm!()
* drop superfluous parens
* drop use of checked_math crate
* manual removal of redundant checked_* functions
- 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 includes trade pnl, funding and fees. Tracking this makes it easier
for uis to display a consistent position overall pnl value that doesn't
decrease by settling.

- Don't return result as I80F48, f64 is more honest
- Allow access to avg entry price per base lot without division
- Reset break even price when position changes sign
- Fix occasionally-failing fast division test
- Fix sign of break even price -- it can now be negative if the
position has broken even.
Since Bank can't expand the existing OracleConfig, add a new one to Bank
and (temporarily!) copy over the old value to the new one in
TokenUpdateIndexAndRate.
Add some reserved space to OracleConfig to make this easier in the
future.
Breaks the PerpMarket and PerpPosition layouts
This introduces the ability to use oracle peg orders on perp markets.
This PR has significant non-backwards compatible changes, for example all
order trees are now in a single account instead of separate.
* Perp instruction logging
* Onchain funding calculation
* perp_spot_transfers field on perp positions
* Logging on register token, perp market
* Additional fields on update token index logging
* maker and taker volume fields on perp position
* Onchain interest calculation
* Fix to TokenBalanceLog for token_liq_bankruptcy (was previously using liqee liab position for liqor liab position).
* Log cumulative interest when token position is deactivated.
Direct access to base_position_lots and quote_position_native is not
allowed anymore.
Fixes an issue where quote_lots were used instead of quote_native, and
also takes fees into account for the entry price.
- Clarification of close_order vs close_all_orders
- Remove of get_ prefixes
- Remove find_min/find_max/find_min_max, duplicated with
min_leaf/max_leaf
- Loan origination fees: The previous approach of tracking the reserved
amount did not work because OutEvents will also reduce the reserved
amount. This means we can't know if it was an OutEvent-cancel or an
order execution that caused the reduction.
Instead, we now track the amount of borrows that was made (without
applying origination fees) in place order. Whenever we try to settle
and the amount of tokens on the oo account is less than the potential
borrows, we can be certain that the borrow has actualized.
- Place order is no longer automatically followed by a settle.
This can reduce compute use when people want to place multiple orders
in sequence. Now they can use the HealthRegion instructions to place
their orders, settle once at the end, and then have health checked.
- Vault check: Place order previously rejected valid orders because it
didn't consider that there could be free tokens on the oo account.
- Tests: Some infrastructure for less verbose serum testing.
