[tor-relays] hardware accelerated crypto

[Joshua Datko]

I was looking into this for the BeagleBone black [1], which has
on-chip accelerators for AES, SHA (1 I think), and md5.  The TI
processor also has a HWRNG.  My belief was that by using the cryptodev
kernel module [2] I could get this working, but I ran in some issues
building the kernel and then I was caught up in other things.

I'm not sure if my approach was flawed or what, but maybe it helps someone here.
