* org.eclipse.cdt.codan.extension/src/org/eclipse/cdt/codan/extension/ExecutionStateClause.java: New file.
* org.eclipse.cdt.codan.extension/src/org/eclipse/cdt/codan/extension/PropertyState.java: Take optional name arg.
* org.eclipse.cdt.codan.extension/src/org/eclipse/cdt/codan/extension/SymbolicState.java: New copy method.
* org.eclipse.cdt.codan.extension/src/org/eclipse/cdt/codan/extension/VariableAssignmentVisitor.java: New file.
* org.eclipse.cdt.codan.extension/src/org/eclipse/cdt/codan/extension/checkers/CloseOpenedFilesChecker.java: See commit message.
* org.eclipse.cdt.codan.extension/src/org/eclipse/cdt/codan/extension/checkers/FunctionNameParser.java: Use IASTNode.
