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
Adds LockupKind::Constant, extends the reset_lockup instruction and
adds the internal_transfer instruction to allow working with constant
maturity lockups.
- 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.
