* RentNotPayed -> RentNotPaid

It is OK to change the in-storage field name because:

1. The SCALE encoding is not based on names only on position.
2. The struct is not public (only to the crate).

* Prevent contracts from allocating a too large buffer

* Fix possible integer overflow

* Do not evict a contract from within a call stack

We don't want to trigger contract eviction automatically when
a contract is called. This is because those changes can be
reverted due to how storage transactions are used at the moment.
More Information:
https://github.com/paritytech/substrate/issues/6439#issuecomment-648754324

It can be re-introduced once the linked issue is resolved. In the meantime
`claim_surcharge` must be called to evict a contract.

* Lazily delete storage in on_initialize instead of when removing the contract

* Add missing documentation of new error

* Make Module::claim_surcharge public

It being the only dispatchable that is private is an oversight.

* review: Add final newline

* review: Simplify assert statement

* Add test that checks that partial remove of a contract works

* Premote warning to error

* Added missing docs for seal_terminate

* Lazy deletion should only take AVERAGE_ON_INITIALIZE_RATIO of the block

* Added informational about the lazy deletion throughput

* Avoid lazy deletion in case the block is already full

* Prevent queue decoding in case of an already full block

* Add test that checks that on_initialize honors block limits

* 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

Updates the copyright years and fixes wrong license headers.

* review: Remove superflous .into()
