[PATCH v2 1/1] libdw: check that DWARF strings are null-terminated

It is expected from libdw to return strings that are null-terminated to avoid overflowing ELF data. * Add calculation of a safe prefix inside string sections, where any string will be null-terminated. * Check if offset overflows the safe prefix in dwarf_formstring. Signed-off-by: Aleksei Vetro
