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.

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.

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.
* 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
This adds three new options to perp markets:
- a flat fee, that is paid for all perp settlements
- given that they exceed the configured min settle amount threshold to
be eligible for fees
- and a fractional fee, that only applies when the benefiting account
has low health and gradually becomes bigger as the account slides
towards liquidation
Perp settle pnl: Limit to maint spot health
We want to isolate perp markets. As such, it's not acceptable to convert
arbitrary perp losses into spot token borrows.
The safe amount for this conversion is given by the account's
maint health -- with all perp markets ignored.
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.
