Previous commit separates durable nonce and blockhash domains with a
feature gate. A 2nd feature added in this commit enables durable nonce
at least one epoch after the 1st feature.
By the time 2nd feature is activated, some nonce accounts will have an
old blockhash, but no nonce account can have a recent blockhash.
As a result no transaction (durable or normal) can be executed twice.
AdvanceNonceAccount instruction updates nonce to blockhash. This makes it
possible that a durable transaction is executed twice both as a normal
transaction and a nonce transaction if it uses blockhash (as opposed to nonce)
for its recent_blockhash field.
The commit prevents this double execution by separating nonce and blockhash
domains; when advancing nonce account, blockhash is hashed with a fixed string.
As a result a blockhash cannot be a valid nonce value; and if transaction was
once executed as a normal transaction it cannot be re-executed as a durable
transaction again and vice-versa.
Indices for code and data shreds of the same slot overlap; and so they
will have the same random number generator seed when shuffling cluster
nodes for turbine broadcast.
This results in the same propagation path for code and data shreds of
the same index and effectively smaller sample size for re-transmitter
nodes. For example a 32:32 batch (32 code + 32 data shreds), is
retransmitted through _at most_ 32 unique nodes, whereas ideally we want
~64 unique re-transmitters.
This commit adds shred-type to seed function so that code and data
sherds of the same (slot, index) will (most likely) have different
propagation paths.

Most nodes in the cluster receive the same shred from two different
nodes: parent, and the first node of their neighborhood:
https://github.com/solana-labs/solana/blob/a8c695ba5/core/src/cluster_nodes.rs#L178-L197
Because of the erasure codings, half of the shreds are already
redundant. So this redundant propagation path will only add extra
overhead.
Additionally the very first node of the broadcast tree has 2x fanout
(i.e. 400 nodes) which adds too much load at one node.
This commit simplifies the broadcast tree by dropping the redundant
propagation path and removing the 2x fanout at root node.
* Moves stack_height of the instruction_trace into InstructionContext.
* Uses nesting_level instead of stack_height internally in transaction_context.rs
* Uses the instruction_trace instead of the instruction_context_stack internally.
* Adds feature gate: record_instruction_in_transaction_context_push.
* 10461 Reject close of vote accounts unless it earned no credits in the previous epoch. This is checked by comparing current epoch (from clock sysvar) with the most recent epoch with credits in vote state.
* Fixup typo
* Add new feature
* Add new TransactionError
* Add framework for checking account state before and after transaction processing
* Fail transactions that leave new rent-paying accounts
* Only check rent-state of writable tx accounts
* Review comments: combine process_result success behavior; log and metrics before feature activation
* Fix tests that assume rent-exempt accounts are okay
* Remove test no longer relevant
* Remove native/sysvar special case
