Fix garbage handling in DMI strings
Previously we tried to replace garbage characters with <space> directly in
the read-only memory-mapped SMBIOS area(!). This could never have
worked for any DMI strings with garbage and results in a segfault on
machines with such strings.
Thanks to Brian Rak (Supermicro X10SLE-F) and John Pohlman (HP XW9400)
for reporting this issue.
With this patch the strings are duplicated within dmi_string() already,
just before we sanitize them. Also, the limit variable used everywhere
points to the first invalid byte address. Refine respective checks
Corresponding to flashrom svn r1824.
