diffutil: provide a generic diffutil implementation

this allows to compare two lists and generate a list of insertions and deletion
from the old list to the new one.

This is useful to UI frontends to preform partial updates of their view when
data change on the backend.

qt: use diff util algorithm to perform partial update of the model

this allows to submit to the view only the changes made on the model when the
database changes instead of invalidating and resetting the whole view.

data cache is changed from a windowed view over the data, to a model where data
is loaded from the start and loaded by chunk (append to the cache), when data is
invalidated the data is reloaded in background and the difference (insertions
and deletions) are propagated to the view.

qt: allow to move or remove range of items from the cache

this would allow to move or update elements in "a priori" before getting the
notification from the database

qt: allow to detect moves in MLList cache

This remains is disabled by default, The extra cost isn't really worth it as
move operations originated from the database are very rare, move operations from
the user are usually handled "a priori".
