* perp: auto close perp market account when needing to open a new one with no slot available
* rust_client: do not send health accounts when deactivating a perp position (not needed on program side)
* rust_client: add perp place order command
Previously serum3_place_order would fail when deposit limits were
exhausted on the payer token side. Now the failure only happens when
payer tokens need to be borrowed.

Previously, we tried to keep track of "other" and "trade" realized pnl.
An issue occured when a perp base position went to zero: the way we
computed the trade pnl included potential non-trade unsettled pnl.
That caused follow-up trouble because the value could change sign and
reset the settle limit for trade pnl.
This change aims to simplify in some ways:
- explicitly talk about oneshot-settleable pnl (fees, funding,
liquidation) and recurring-settleable pnl (materialization of settle
limit derived from the stable value of the base position when reducing
the base position)
- instead of directly tracking realized settleable amounts (which
doesn't really work), just decrease the recurring settleable amount
when it exceeds the remaining unsettled pnl
- get rid of the directionality to avoid bugs of that kind
- stop tracking unsettled-realized trade pnl (it was wrong before, and
no client uses it) - we already track position-lifetime realized trade
pnl

The liqor liquidation fee and platform liquidation fee for the asset and
liab token are both payed by the liqee.
The platform liquidation fee is added to the Bank's
collected_fees_native and tracked in collected_liquidation_fees.

- require borrows <= deposits, even if vaults have more tokens
- change min_vault_to_deposits_ratio to be about max utilization

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.
