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.
Move all syscall declarations under solana_program::syscalls. If the target
supports static syscalls (sbfv2), then actually define them statically to avoid
dynamic relocations.
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.

* Move a computation to where it's actually needed in is_writable(), which speeds up the code.
* Simplified a bool expr, even though it's a little less clear now
* Reorganize to make demote_program_id explicit again
* Remove the unnecessary let; replace it with a comment
* try different comment style
* Used cargo fmt that time
* Made demote_program_id its own function, for clarity
