* Fix output of wrongly outputted error

The "Tombstoned a contract that is below the subsistence threshold: {:?}" was
triggered when too few balance was provided. It was a false alarm.

* Fix return of wrong code_len

* Split up `NotCallable` into more fine grained errors

* Fix typos in docs

* RentNotPayed -> RentNotPaid

* Fix typo: payed -> paid

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).

use of multiple prefix. Like one to store how much value has been
inserted, etc...

* Fix max_size using hasher information

hasher now expose `max_len` which allows to computes their maximum len.
For hasher without concatenation, it is the size of the hash part,
for hasher with concatenation, it is the size of the hash part + max
encoded len of the key.

* Remove grandpa StoredPendingChange shim

* Unused import

* emit a custom section from impl_runtime_apis!

This change emits a custom section from the impl_runtime_apis! proc macro.

Each implemented API will result to emitting a link section `runtime_apis`.
During linking all sections with this name will be concatenated and
placed into the final wasm binary under the same name.

* Introduce `runtime_version` proc macro

This macro takes an existing `RuntimeVersion` const declaration, parses
it and emits the version information in form of a linking section.
Ultimately such a linking section will result into a custom wasm
section.

* requiring users to maintain an unchecked invariant is unsafe

* relax trait restrictions on BoundedVec<T, S>

A normal `Vec<T>` can do many things without any particular trait
bounds on `T`. This commit relaxes the bounds on `BoundedVec<T, S>`
to give it similar capabilities.

* contracts: Add default implementation for Executable::occupied_storage()

* contracts: Refactor the exec module

* Let runtime specify the backing type of the call stack

This removes the need for a runtime check of the specified
`MaxDepth`. We can now garantuee that we don't need to
allocate when a new call frame is pushed.
