This is done because at the time of writing cargo-unleash does not fully
support partial workspace publishing and mixes both local and crates.io
versions of the packages, leading to errors in the release check workflow.

* 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

* Improve fn write docs

* Renamed state to phantom

* Fix typo

* Happy new year

Updates the copyright years and fixes wrong license headers.

* 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

* review: Remove superflous .into()

* Make it possible to calculate the storage as often as you want

So, until now each Substrate based blockchain has calculated the storage
root once, at the end of the block. Now there is Frontier that wants to
calculate some intermediate storage root. However this failed on block
import. The problem with that was the extrinsics root. When building the
block we stored `Default::default()` as extrinsics root, because yeah,
we don't know the extrinsics root before finishing the block. At the end
this extrinsics root was then calculated. But on block import we passed
the already known extrinsics root. This was no problem, as we removed
this value at the end of the block. However when you all the storage
root in between, that changes the storage root between block building
and block import.

This pr changes this behavior. It removes the `ExtrinsicsRoot` storage
entry and also doesn't pass it anymore to `System::initialize`. By doing
it, we remove the difference in the storage and fix the storage root mismatch.

* Fix bug with incorrectly calculating the extrinscs root

* Review feedback

This is no longer necessary with storage transactions.

* fix docs

* Update frame/merkle-mountain-range/src/lib.rs

* manual rename

* renamse in README.md

* fix template

* rename Trait to Config

* add test asserting using Trait is still valid.

* fix ui tests

* pallet-contracts: Fix seal_restore_to to output proper module errors

Those errors where part of the decl_error for some time but where
never actually returned. This allows proper debugging of failed
restorations. Previously, any error did return the misleading
`ContractTrapped`.

* Bind UncheckedFrom<T::Hash> + AsRef<[u8]> everywhere

This allows us to make assumptions about the AccoutId
that are necessary for testing and in order to benchmark
the module properly.

This also groups free standing functions into inherent functions
in order to minimize the places where the new bounds need to
be specified.

* Rework contract address determination

* Do not allow override by runtime author
* Instantiate gained a new parameter "salt"

This change is done now in expecation of the upcoming code rent
which needs to change the instantiation dispatchable and
host function anyways.

The situation in where we have only something that is like CREATE2
makes it impossible for UIs to help the user to create an arbitrary
amount of instantiations from the same code.

With this change we have the same functionality as ethereum with
a CREATE and CREATE2 instantation semantic.

* Remove TrieIdGenerator

The new trait bounds allows us to remove this workaround
from the configuration trait.

* Remove default parameters for config trait

It should be solely the responsiblity to determine proper values for
these parameter. As a matter of fact most runtime weren't using these
values anyways.

* Fix tests for new account id type

Because of the new bounds on the trait tests can't get away by using
u64 as accound id. Replacing the 8 byte value by a 32 byte value
creates out quite a bit of code churn.

* Fix benchmarks

The benchmarks need adaption to the new instantiate semantics.

* Fix compile errors caused by adding new trait bounds
* Fix compile errors caused by renaming storage and rent functions
* Adapt host functions and dispatchables to the new salt
* Add tests for instantiate host functions (was not possible before)

* Add benchmark results

* Adapt to the new WeightInfo

The new benchmarks add a new parameter for salt "s" to the instantiate weights
that needs to be applied.

* Fix deploying_wasm_contract_should_work integration test

This test is adapted to use the new instantiate signature.
