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.).
