This allows the security council to say "users can't create new borrows
against this token/perp anymore". In some emergency situations this can
help reduce risk exposure.
For example, if the price of a wrapped asset permanently depegs from
its underlying or there is a successful long-term attack on an oracle,
this (and reduce-only) would significantly reduce exploitability until
the DAO's decision for how to resolve the issue goes through.
* 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
To do that, split up the Accounts objects and the instruction
implementations.
GPL code is only used when the "enable-gpl" feature is enabled. That
means compiling the program or running tests need explicit feature
activation now.
Due to the safety features in v4, the init health can differ from maint
health a lot more than it used to in v3. This is because of stable-price
adjusted oracle prices used in init health, and the weight scaling based
on total deposits and borrows used in init health.
The effect is that once an account becomes liquidatable, it could be
liquidated a lot until it reaches init>=0.
The original idea of liquidating until init>=0 was just to provide some
buffer, such that liquidated accounts wouldn't immediately become
liquidatable again.
This patch decouples the buffer idea explicit from init health by
creating a new LiquidationEnd health type. Liquidation proceeds until
the LiquidationEnd health becomes positive.

Previously liquidation would overestimate the amount required, because
it used the oracle price for computing the health gain from
liquidation.
Now it uses the correct (stable price adjusted) price for figuring out
the amount of liquidation required, while still executing at
fee-adjusted oracle price.
- don't store internal order ids: unneeded
- provide the maker client order id for user correlation
- store fees as f32 to waste fewer bytes
- new FillLogV2
- 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
Speeds up the linking step, needs way less disk space for test binaries
and executes tests significantly faster.
Test execution went from 35s -> 29s for me and compilation improved a
lot.

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.

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.

The new instruction allows the liqor to take over negative pnl (limited
by liqee settle health and settle limits) before applying the bankruptcy
logic.
It's likely for perp pnl to oscillate and be settled in positive and
negative direction repeatedly. If the user's USDC balance is <= 0, every
settlement of negative pnl will increase borrows and cause loan
origination fees.
Over time the fees accumulated this way could be significant. Skipping
loan origination fees for borrows created from perp settlement avoids
that.
This gives us better compatibility with released anchor versions.
Instead of using AccountLoaderDynamic<MangoAccount>, we now use
a standard AccountLoader<MangoAccountFixed>. This will generally work
(except for load_init(), which is dangerous).
A new trait, MangoAccountLoader, provides load_full(), load_full_mut()
etc on the AccountLoader<MangoAccountFixed> to create accessor structs
that can read and write to the dynamic part of the mango account data.
While the flag is true, deposits that don't bring the account health
over the init threshold are forbidden. This makes it impossible for
users to drag out liquidation by continuously depositing tiny amounts.
Liquidation and perp pnl settlement may not bring spot amounts to
exactly zero. Having a small spot amount < 1 native token can otherwise
make the liquidation get stuck and not move one to the next phase.
* Client: Rework max_swap function
Determining the amounts at which the health function changes slope
becomes too difficult when serum3 open orders come in.
Instead, generally find the function's maximum and then work with that.

Liquidator, liqtest and rust client fixes
- Make rust MangoClient fully async
- Update and improve liquidation test setup scripts
- Update liquidator to use versioned transactions
- Update liquidator to use mango and jupiter account lookup tables
- Use jupiter v4 api to get versioned transactions
Perp liquidation is still not fully good. See discussion aboult perp_liq_pnl_with_token.
* dont do checks force close flag is used explicitly
