Detailed Description

Each Child object stands for one DataSource (i.e. SingleUrl/CachedUrl) which the MakeImageDl starts as a "child download" of itself.

The Child maintains a private pointer to a DataSource. It also listens to what happens to the DataSource and informs the parent MakeImageDl e.g. of succeeded downloads.

Used to store additional information which the MakeImageDl needs, e.g. the filename in the cache.

The ctor and dtor automatically add/remove the Child in its master MakeImageDl's list of children. Careful, this class derives twice from IListBase, once via ChildListBase, once via Job::DataSource::IO.
