This function transfroms the given TEventList into a TEntryList.
NOTE, that this function loads all tree headers, because the entry numbers in the TEventList are global and have to be recomputed, taking into account the number of entries in each tree.
The new TEntryList is owned by the TChain and gets deleted when the chain is deleted. This TEntryList is returned by GetEntryList() function, and after GetEntryList() function is called, the TEntryList is not owned by the chain any more and will not be deleted with it.
