Filtering on analysis callstacks

This module creates and manages the "Values" panel on the lower notebook of the GUI. It mainly displays the values computed by the analysis for selected expressions and lvalues, and thus depends on the value abstractions used for the analysis. It is able to display different values by callstacks in a table, in accordance with the callstacks focused by the user (handled in gui_callstacks_filters.ml).

This module defines an abstraction to evaluate various things across multiple callstacks. Currently, l-values, NULL, expressions, term-lvalues, terms and predicates can be evaluated
