23a1914d7e Optimize SelectionList::update in the case where changes are backward 
This case arise on undo, reverse sorted changes that are not overlapping.

49ab0c101a Use forward iteration on selections, and take advantage of it when updating 
SelectionList::update now is optimized for the common case where changes
are sorted, the algorithm is O(m*n) with m the number of sorted ranges
in the changes. In the common case, m should be very small.

f49bec8021 Go back to Buffer::Change based implementation for SelectionList::update 
However take into account the ordering of selections in insert and erase
methods, so that we update selection position cheaply.

b2621ca140 Move insert/erase methods from normal.cc to member functions in SelectionList 
It does look like the Editor class is attempting a sneaky comeback...

2c52b8bca6 Add initial (and probably buggy) compute_modifications code 
compute_modifications compiles a list of buffer change into
a list of Modifications that can be used for updating BufferCoord

4e280977a2 Iterate in reversed order on selections when modifing buffer 
This way, update only needs to be called once everything is done
as we always modify after the next selection to be used.

cfd7ee049a move selection updating code out of selection, to DynamicSelectionList 
this avoids a lot of unnecessary (add|remove)_change_listener as
creating temporary Selections do not call that anymore.

Use can choose between a SelectionList which or a DynamicSelectionList
depending on wethear the buffer will be modified or not during the
selections lifetime.

e4b872abd2 remove ModificationListener and use a list of iterators to update instead 
This permits to fix a bug in BufferIterator::upgrade, replaced by
BufferIterator::on_insert and BufferIterator::on_erase. ModificationListener
was only used to updating iterators anyway.

0ba7c7286d Store buffer content in a list of lines 
Instead of a big std::string, buffer now store it's content in a
list of lines. In order to achieve O(log(n)) random access, lines
contains both their content and their offset since the start of
the file, making binary search usable.

BufferIterator now have a LineAndColumn coordinate into the buffer
instead of an offset so that access is still O(1).
