prevents rent paying accounts creation going forward. However a rent
paying account can linger on for ever if it is continually topped up but
stays below the rent-exempt minimum.
This can prevent eliminating accounts-rewrites and the problematic
rent_epoch field in accounts.

prevents rent paying account creation going forward. As a result
rent_epoch field for rent exempt accounts is redundant, and advancing
this field will incur expensive account rewrites and cause discrepancy
between accounts-db and cached vote/stake accounts.
This commit adds a feature which upon activation preserves rent_epoch
field for rent exempt accounts so that the field is frozen and is no
longer advanced.
This partially reverts commit 47e62add5b.
Adding back the feature-id so that the master branch can successfully
run ledger-tool across epoch-boundary which enabled the feature.
Note that #25963 backport did not remove the feature-id.

separated durable nonce and blockhash domains, which will stop double
execution going forward. However it is possible that a durable
transaction has *already* been executed once as a normal transaction and
it is now a valid durable transaction. #25744 cannot stop such
transactions to be re-executed until the nonce accounts are advanced.
This commit adds a new nonce version indicating that the nonce is moved
out of the blockhash domain, and permanently disables durable
transactions for legacy nonces which are in the blockhash domain.
* Award one credit per dequeued vote when processing VoteStateUpdate instruction,

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.
Packets are at the boundary of the system where, vast majority of the
time, they are received from an untrusted source. Raw indexing into the
data buffer can open attack vectors if the offsets are invalid.
Validating offsets beforehand is verbose and error prone.
The commit updates Packet::data() api to take a SliceIndex and always to
return an Option. The call-sites are so forced to explicitly handle the
case where the offsets are invalid.
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.
Bytes past Packet.meta.size are not valid to read from.
The commit makes the buffer field private and instead provides two
methods:
* Packet::data() which returns an immutable reference to the underlying
buffer up to Packet.meta.size. The rest of the buffer is not valid to
read from.
* Packet::buffer_mut() which returns a mutable reference to the entirety
of the underlying buffer to write into. The caller is responsible to
update Packet.meta.size after writing to the buffer.
* Removes the offset InstructionContext::get_number_of_program_accounts() from InstructionAccount::index_in_caller.
* Removes unreachable SyscallError::InvalidLength in orig_data_lens.get().
* Introduces result return types to get_data_mut(), set_data() and set_data_length() of BorrowedAccount.
* Introduces result return types to set_owner(), set_lamports() and set_executable() of BorrowedAccount.

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.
