Renaming ecma_Object_t::u_Attributes to u.

Renaming ecma_CompletionValue_t:: completion_type to type, completion_value to value. Introducing ECMA_TARGET_ID_RESERVED value of ecma_CompletionValue_t::target when it is unused. Adding ecma_Reference_t type for ECMA-reference. Introducing some constructors and helpers for ecma-values. Introducing ecma_FindNamedProperty helper. Removing ecma_SyntacticReference_t type. Implementing ecma operation GetIdentifierReference. Stubs and partial implementation for GetValue, SetValue, lexical environment operations (HasBinding, etc.).
