libSceXml technical debt

Known export names; ABI prototypes unverified

• 107 of the 150 sce::Xml exports in Export.cpp are present in the PS5 3.20 libSceXml export inventory from PS5-3.20_Libs. Each is named after the mangled symbol the verified NID name database gives for its NID, and the NID of that name matches. Their prototypes and behavior are not established; these 107 use the existing no-parameter import-resolution convention and throw through NotImplemented_nid_no_patch. The declarations do not claim an ABI or behavior.

Value types and handle constructors

• The String, SimpleData, SerializeParameter, NodeId and Node value operations and the handle constructors (libSceXml) - follow libSceXml.sprx of firmware 13.60, read from disassembly, not measured on a console. NodeId::operator void* returns null for every NodeId, and the NodeId constructor and copies leave its padding bytes untouched. The handle constructors only clear the implementation pointer. Exports that read the objects initialize builds still throw, because nothing creates those objects yet: AttributeList getLength and isAvailable, Document::resetStatus, the DocumentBuilder and Sax::Parser setters, Node(NodeId), and Node getNodeType, hasChildNodes, hasAttributes and getOwnerDocument. Node::getAttributes and getChildNodes are a bare return in the module, and the deleting MemAllocator destructor is ud2, so they still throw too.
