removes lazy-static thread-pool from sigverify-shreds (#30787)
Instead the thread-pool is passed explicitly from higher in the call
stack so that
https://github.com/solana-labs/solana/pull/30786
can use the same thread-pool for shred deduplication.

removes the merkle root from shreds binary (#29427)
https://github.com/solana-labs/solana/pull/29445
makes it unnecessary to embed merkle roots into shreds binary. This
commit removes the merkle root from shreds binary.

This adds 20 bytes to shreds capacity to store more data.
Additionally since we no longer need to truncate the merkle root, the
signature would be on the full 32 bytes of hash as opposed to the
truncated one.

Also signature verification would now effectively verify merkle proof as
well, so we no longer need to verify merkle proof in the sanitize
implementation.

recovers merkle roots from shreds binary in {verify,sign}_shreds_gpu (#29445)
{verify,sign}_shreds_gpu need to point to offsets within the packets for
the signed data. For merkle shreds this signed data is the merkle root
of the erasure batch and this would necessitate embedding the merkle
roots in the shreds payload.
However this is wasteful and reduces shreds capacity to store data
because the merkle root can already be recovered from the encoded merkle
proof.

Instead of pointing to offsets within the shreds payload, this commit
recovers merkle roots from the merkle proofs and stores them in an
allocated buffer. {verify,sign}_shreds_gpu would then point to offsets
within this new buffer for the respective signed data.

This would unblock us from removing merkle roots from shreds payload
which would save capacity to send more data with each shred.

with empty data. This preserves invariants verified in tests regardless
of data size.

removes raw indexing into packet data (#25554)
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.

behzad nouri 81231a89b9 adds support for different variants of ShredCode and ShredData
The commit implements two new types:
    pub enum ShredCode {
        Legacy(legacy::ShredCode),
    }
    pub enum ShredData {
        Legacy(legacy::ShredData),
    }

Following commits will extend these types by adding merkle variants:
    pub enum ShredCode {
        Legacy(legacy::ShredCode),
        Merkle(merkle::ShredCode),
    }
    pub enum ShredData {
        Legacy(legacy::ShredData),
        Merkle(merkle::ShredData),
    }

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.

Make PacketBatch packets vector non-public (#25413)
Upcoming changes to PacketBatch to support variable sized packets will
modify the internals of PacketBatch. So, this change removes usage of
the internal packet struct and instead uses accessors (which are
currently just wrappers of Vector functions but will change down the
road).

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.

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]>:
