Modify merge to handle implications properly

This introduces an overhaul of the merging process as a
whole in order to properly handle implications (a diff
implied by another does not need merging in itself, we
only need to merge the implying), most notably for the UML
comparison support.

The same algorithm is now used to merge differences in a
batch (or to simply merge implications, results and
equivalences) and to display the impact analysis of a merge
in the user interface (what will be merged and what will be
rejected when I merge such or such difference).

Merge "Modify merge to handle implications properly"
Pre-merge from EMF logical merging

This also introduces an in-depth impact analysis facility
that allows EMF Compare to automatically pre-merge
everything that can be (i.e everything that is not in
conflict or does not depend on a conflict resolution). This
is notably used within the logical merging, but could also
be used for the "merge all non-conflicting" actions of the
user interface.

Prevents loading twice the same model in a NotLoadingResourceSet.

The previsous getResource(IStorage,boolean) method did not check if a
resource was already loaded. It may happen that the same resource was
created twice in the same ResourceSet (with the exact same uri).

This commit also changes the way IStorage are loaded in the resource
set. The IStorages are now loaded using their uris. The resource set is
aware of the resources that should be loaded from a IStorage.

Adds ResourceSetHook extension point.


This extension point aims to provide a way for external client to hook
some behavior into the ResourceSet used by EMF Compare (for example
register new factories).

[446739] Fixes obtaining the target feature in three-way merge of a move

We now make sure that the target feature is correctly determined. This
prevents a NullPointerException thrown during a three-way merge of a
move, in which the target containment feature is not available in the
type of the original containment feature.

[441172] Fix merge order of equivalent diffs for one-to-one opposites

When determining which one of the equivalent differences of one-to-one
eOpposites will be merged above the others, differences which result in
setting a feature value instead of unsetting a feature will be
preferred.

Includes testcases for both merge directions.

[448120] Adds FeatureMapChangeSpec with a useful toString() method

To ease debugging feature map changes, we introduce a new subclass
FeatureMapChangeSpec, corresponding to the already existing
ReferenceChangeSpec and AttributeChangeSpec, with a useful toString()
method providing all necessary information about a feature map change of
interest.

negative numbers...)
