commit b2dddd3389a8005a7e93bc21b2932156899e1aac
Author: Mark Wielaard <mark@klomp.org>

unstrip: Check symbol strings are terminated.
A corrupt ELF file could contain a .strtab section that wasn't
properly zero terminated. If so we could add a non-terminated string
to the dwelf_strtab functions, which could then crash because they
would read past the .strtab section data.
