* 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()
* 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.

* seal: Add capability to put uninstrumented code (for benchmarks)
Benchmarks should only measure the overhead of the API calls itself.
For that reason we want to run them without instrumentation.

Data used in events has storage implications for archive nodes.
Those need to keep the events in storage forever. For that reason
we want to limit the amount of storage that can be used inside events.

* seal: Change prefix "ext_" to "seal_" for contract callable functions
The word Ext is a overloaded term in the context of substrate. It usually
is a trait which abstracts away access to external resources usually in order
to mock them away for the purpose of tests. The contract module has its own
`Ext` trait in addition the the substrate `Ext` which makes things even more
confusing.
In order to differentiate the contract callable functions more clearly from
this `Ext` concept we rename them to use the "seal_" prefix instead.
This should change no behaviour at all. This is a pure renaming commit.

* with_nested_context no longer accepts an Option for trie
* Fix successful typo
* Rename InvalidContractCalled to NotCallable
* seal: Fix syntax that confuses rust-analyzer
* seal: Add benchmarks for Dispatchables
These are only the benchmarks for the dispatchables of
the pallet. Those are not listed in the Schedule because
we do not want to pull the Schedule from storage before
dispatching.
This OK because those costs are not related to actual contract
execution. Those costs (instruction costs, ext_* costs) will
be benchmarked seperatly and entered into the default Schedule.

With this patch forward this will be the only way for
a contract to destroy itself. This patch therefore changes
the semantics of all other contract initiated balance
transfers to fail if they would bring the caller below the
existential deposit.
* contracts: Add ext_transfer call
This call allows contracts to send balance to any account
contract or not. Previously, the only way to do that was
though ext_call.

* Make `decl_error!` errors usable
This pr implements support for returning errors of different pallets in
a pallet. These errors need to be declared with `decl_error!`.
The pr changes the following:
- Each dispatchable function now returns a `DispatchResult` which is an
alias for `Result<(), DispatchError>`.
- `DispatchError` is an enum that has 4 variants:
- `Other`: For storing string error messages
- `CannotLookup`: Variant that is returned when something returns a
`sp_runtime::LookupError`
- `BadOrigin`: Variant that is returned for any kind of bad origin
- `Module`: The error of a specific module. Contains the `index`,
`error` and the `message`. The index is the index of the module in
`construct_runtime!`. `error` is the index of the error in the error
enum declared by `decl_error!`. `message` is the message to the error
variant (this will not be encoded).
- `construct_runtime!` now creates a new struct `ModuleToIndex`. This
struct implements the trait `ModuleToIndex`.
- `frame_system::Trait` has a new associated type: `ModuleToIndex` that
expects the `ModuleToIndex` generated by `construct_runtime!`.
- All error strings returned in any module are being converted now to `DispatchError`.
- `BadOrigin` is the default error returned by any type that implements `EnsureOrigin`.
