[coreboot] Upgrade the 12 years old LZMA libraries - should we do it?

[Ivan Ivanov]

I have noticed that both coreboot and seabios are using the very old
versions of LZMA SDK. If we will upgrade our LZMA libraries from the
outdated-by-12-years 4.42 to the current version 18.04 , speed and
compression ratio should improve and maybe a few bugs will be fixed.
Do you think it should be done, or you are OK with using such an
outdated version?

Best regards,
