The CRC implementation imported from libgcrypt 1.5.3 is arguably non-free, due to being encumbered by the restrictive Internet Society licence on RFCs (see e.g. https://wiki.debian.org/NonFreeIETFDocuments). Fortunately, libgcrypt has since replaced it with a version that is both reportedly better-optimised and doesn't suffer from this encumbrance. The ideal solution would be to update to a new version of libgcrypt, and I spent some time trying to do that. However, util/import_gcry.py requires complex modifications to cope with the new version, and I stalled part-way through; furthermore, GRUB's libgcrypt tree already contains some backports of upstream changes. Rather than allowing the perfect to be the enemy of the good, I think it's best to backport this single change to at least sort out the licensing situation. Doing so won't make things any harder for a future wholesale upgrade. This commit is mostly a straightforward backport of https://git.gnupg.org/cgi-bin/gitweb.cgi?p=libgcrypt.git;a=commitdiff;h=06e122baa3321483a47bbf82fd2a4540becfa0c9, but I also imported bufhelp.h from libgcrypt 1.7.0 (newer versions required further changes elsewhere). I've tested that "hashsum -h crc32" still produces correct output for a variety of files on both i386-pc and x86_64-emu targets.
