Version 0.8.0

Adds two new DWARF Frame interface functions which correct a mistake in an argument type used to return a value to the caller. The existing functions remain in place so no recompiling or relinking is required. Documentation explains how to use the existing functions (via a cast) so the existing versions can be used correctly.

More than 10 vulnerabilities were fixed. So even reading corrupt Elf/DWARF will not result in memory corruption or a crash.
