Add CFB mode support. CFB uses segment size = block size.

I'm getting late into this discussion, but it seems that samba (which uses nettle and gnutls), could benefit from an 8-bit CFB mode as well. They are already implementing it on top of nettle, and it is being used on the newer samba versions:

Hmm, interesting. It looks like they miss CFB8 and CMAC. However from the first glance I could not understand, do they reference nettle/ GNUTLS as code reference, or are they using them as crypto backends? Skimming over WAF scripts did not give me the answer.
I can (re-)post CFB8 if that will be helpful to Samba (or other parties). CMAC also sounds like and interesting topic.
