p-ATA tracking issue

[grod220]

Task breakdown to deploying p-ata, a pinocchio-based Associated Token Account program.

CreateAccountAllowPrefund

CreateAccountAllowPrefund is a system program instruction that permits account creation when the target account already has lamports (prefunded). It is a dependency for p-ata.

• SIMD-0312: add CreateAccountAllowPrefund system instruction anza-xyz/solana-sdk#352
• add CreateAccountAllowPrefund, feature-gated anza-xyz/agave#9647
• Rekey create_account_allow_prefund feature anza-xyz/agave#9805
• programs/system: Rename payer to from anza-xyz/agave#10658
• feature-set: Rekey create-account-allow-prefund anza-xyz/agave#10708
• add CreateAccountAllowPrefund builder anza-xyz/pinocchio#307
• Confirm stable Agave lib release containing create_account_allow_prefund (currently in v4.0.0-alpha.0)
• Mollusk update. Currently it's pinning solana-system-interface = "2.0".

p-ATA

• Core PR to supersede: (Replaced) p-ata #102
• Update solana-program-test tests to mollusk (with helper harness) #131
• Scaffold pinocchio crates #197
• p-ata: Idempotent w/ existing ATA #200
• Implement RecoverNested ix migration
• Evaluate optimizations:
  • bump hint
  • token_account_len len hint
  • optional rent account
  • inline parsing of known Token-2022 mint extensions to avoid GetAccountDataSize CPI
  • p-ata: create flow pt. 2 + sizing #204
• token-2022: Add TLV extension state infrastructure and initial extension structs anza-xyz/pinocchio#349
• Update to agave/mollusk/pinocchio 4.0 lib versions
• Fuzzing: review febo's and joe's guides.
• Add p-ata instruction creators to the interface crate #137
• SIMD published
• Fresh benchmarks
• SIMD-0418: Enable Loader v2 to v3 Program Migrations solana-foundation/solana-improvement-documents#418
• Formal verification (?)
• Security audit + remediation
• Devnet -> Testnet -> Mainnet activation
• Docs follow up Document security hazards of system_interface::instruction::create_account anza-xyz/solana-sdk#416
