Christian Kamm 22b4923ef2 Address all math issues reported by soteria
None of these should have been a real issue.

Christian Kamm 40708e80ef Fix underflow in voting computation
The vote power computation was broken for lockups that start very far
in the future.

- Fix the underflow itself
- Disallow lockups that start more than 100 years in the future
- Error if the lockup-scaled voting power is bigger than the maximum
  lockup voting power

Christian Kamm 49e137eb51 Add constant-maturity lockup
Adds LockupKind::Constant, extends the reset_lockup instruction and
adds the internal_transfer instruction to allow working with constant
maturity lockups.

Christian Kamm 9a5182d317 Fix a bug where start_ts could become > end_ts
Previously period_current() could exceed periods_total().

Christian Kamm decdd1230c Address unaligned references, add padding
- Make Registrar zero-copy. While it was using borsh for serialization,
  the array of voting mint configs couldn't be serialized without
  unaligned references.
- Reorganize all zero_copy fields such that switching to repr(C) would
  not make a difference. (just for safety in case that happens)
- Add static asserts on the sizes of all account structs, so any changes
  are visible very early.
- Add padding to structs that didn't have it yet.

Christian Kamm e8b0a1f50a Fix vote power computation for monthly vesting
- The vote power decay now has second resolution.
- Monthly and daily vesting behave exactly like multiple cliff locked
  deposits.
- In particular, monthly vesting deposits lock-up power decays during
  the month, making it smooth over time.
- Gain vote power even if start_ts is in the future (shouldn't happen)

Christian Kamm b91f9ba595 Pass deposit_entry_index to create_deposit_entry()
This allows create_deposit_entry() and deposit() to be in the same
transaction.
