* Make host functions return TrapReason This avoids the need to manually store any trap reasons to the `Runtime` from the host function. This adds the following benefits: * It properly composes with the upcoming chain extensions * Missing to set a trap value is now a compile error * Add chain extension The chain extension is a way for the contract author to add new host functions for contracts to call. * Add tests for chain extensions * Fix regression in set_rent.wat fixture Not all offsets where properly updated when changing the fixtures for the new salt on instantiate. * Pre-charge a weight amount based off the specified length * Improve fn write docs * Renamed state to phantom * Fix typo
