    Bastian Köcher authored
    * Move module metadata from json string to custom metadata
    
    * Revisit the metadata structures
    
    1. Move the structures into the metadata crate.
    2. Switch to using Cow/MaybeOwnedArray to support Encode/Decode
    
    * Adapt to new metadata structures
    
    * Convert event json metadata to new metadata structures
    
    * Convert storage json metadata to new metadata structures
    
    * Convert runtime metadata from json to new metadata structs
    
    * Implements new metadata structures in client and runtime
    
    * Fixes errors on `no_std`
    
    * Fixes errors after rebasing master
    
    * Do not use `Cow` anymore in metadata
    
    Also replace `String` with our own type definition `StringBuf`.
    This fixes compilation on `no_std`.
    
    * Wrap `RuntimeMetadata` in `RuntimeMetadataVersioned` to support versioning
    
    * Move metadata into `srml` and make core unaware of the implementation
