By default the extra section is merged with array_merge() and duplicate
keys are ignored. When enabled this allows to merge the arrays recursively
using the following rule: Integer keys are merged, while array values are
replaced where the later values overwrite the former.
This is useful especially for the extra section when plugins use larger
structures like a 'patches' key with the packages as sub-keys and the
patches as values.
When 'replace' mode is activated the order of array merges is exchanged.
