Modeled on QByteArrayData/QStringData/QVectorData, the intent is to unify book-keeping structs for array-like data and enable sharing of code among them. As in those structures, size (and alloc) data member(s) specify the number of *typed* elements the array does (and can) hold. The size or alignment requirements of those objects is not tracked in this data structure and needs to be maintained by its users. Contrary to QByteArrayData and QStringData, QArrayData's offset member keeps a *byte* offset to the actual data array and is computed from the beginning of the struct. Shared-null and -empty functionality is provided by QArrayData and shared among all users. Planned features include setSharable (force deep copies), fromRawData (detached header and data allocations) and literals a la QStringLiteral (static immutable instances), thus covering the functionality needed for QByteArray, QString and QVector.
