Ensure that all members of LinearView and HexEditor are initialized

Most members were initialized within the constructor, but a couple were
only initialized later and could in some cases be accessed before being
initialized.

Members of types without default constructors are now initialized via
default member initializers unless they're initialized in the class's
member initializer list.
