verifies shred slot and parent in fetch stage ( #26225 )
...
Shred slot and parent are not verified until window-service where
resources are already wasted to sig-verify and deserialize shreds.
This commit moves above verification to earlier in the pipeline in fetch
stage.

removes shred wire layout specs from sigverify ( #25520 )
...
sigverify_shreds relies on wire layout specs of shreds:
https://github.com/solana-labs/solana/blob/0376ab41a/ledger/src/sigverify_shreds.rs#L39-L46
https://github.com/solana-labs/solana/blob/0376ab41a/ledger/src/sigverify_shreds.rs#L298-L305
In preparation of
https://github.com/solana-labs/solana/pull/25237
which adds a new shred variant with different layout and signed message,
this commit removes shred layout specification from sigverify and
instead encapsulate that in shred module.

limits read access into Packet data to Packet.meta.size ( #25484 )
...
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.

enforces that LAST_SHRED_IN_SLOT is also DATA_COMPLETE_SHRED ( #24892 )
...
A data shred cannot be LAST_SHRED_IN_SLOT if not also DATA_COMPLETE_SHRED.
So LAST_SHRED_IN_SLOT should also imply DATA_COMPLETE_SHRED:
https://github.com/solana-labs/solana/blob/74b586ae7/ledger/src/shredder.rs#L116-L117
https://github.com/solana-labs/solana/blob/74b586ae7/core/src/broadcast_stage/standard_broadcast_run.rs#L80-L81
However current shred constructs allow specifying a shred which is
LAST_SHRED_IN_SLOT but not DATA_COMPLETE_SHRED:
https://github.com/solana-labs/solana/blob/74b586ae7/ledger/src/shred.rs#L117-L118
https://github.com/solana-labs/solana/blob/74b586ae7/ledger/src/shred.rs#L272-L273
The commit updates ShredFlags so that if a shred is not
DATA_COMPLETE_SHRED it cannot be LAST_SHRED_IN_SLOT either.

replaces Shred::new_empty_coding with Shred::new_from_parity_shard ( #24749 )
...
Removing implementation details of shreds and payload offsets from
shredder, so that shredder does not need to mutate payload:
https://github.com/solana-labs/solana/blob/71ad12128/ledger/src/shred.rs#L968-L977
Also, Shred::new_from_data can simply obtain a slice as opposed to
Option<&[u8]>:
