Import of segment model

This merge request offers implementation of the segment-based shadow memory model for E-ACSL.

The initial import (via commit 7544180fe1ff948e7c553cf483a31464fb17510e) has been combined with safe locations feature, which is required for seamless integration of the segment model to the present state of E-ACSL. Note, this merge request is essentially the same as the latest MR from my private fork of E-ACSL.

Fix wrong compile flags in debug mode during compilation of instrumented executables

Change __e_acsl_heap_size  to __e_acsl_heap_allocation_size
