59f9097d5c Hand-conversion and audit phase of memcmp transition
Here I looked at the results of the automated conversion and cleaned
them up as follows:

   If there was a tor_memcmp or tor_memeq that was in fact "safe"[*] I
   changed it to a fast_memcmp or fast_memeq.

   Otherwise if there was a tor_memcmp that could turn into a
   tor_memneq or tor_memeq, I converted it.

This wants close attention.

[*] I'm erring on the side of caution here, and leaving some things
as tor_memcmp that could in my opinion use the data-dependent
fast_memcmp variant.

4b19730c82 Add a data-independent variant of memcmp and a d-i memeq function.
The tor_memcmp code is by Robert Ransom, and the tor_memeq code is
by me.  Both incorporate some ideas from DJB's stuff.
