Access to special accounts with dynamically-updated data.

Sysvars are special accounts that contain dynamically-updated data about the network cluster, the blockchain history, and the executing transaction. Each sysvar is defined in its own crate. The clock, epoch_schedule, instructions, and rent sysvars are most useful to on-chain programs.

All sysvar accounts are owned by the account identified by clone_solana_sysvar::ID.

For more details see the Solana documentation on sysvars.
