Big changes for curve flexibility. For details see HISTORY.txt.
Very experimental Ed480-Ridinghood support is now in. It's not fully optimized, but in general the current build is 8-15% slower than Goldilocks. It only works on arch_x86_64, though arch_ref64 support ought to be easy. Support on other arches will be trickier, which is of course why I chose Goldilocks over Ridinghood in the first place. Next up, E-521. Hopefully. The code is starting to get spread out over a lot of files. Some are per field*arch, some per field, some per curve, some global. It's hard to do much about this, though, with a rather ugly .c.inc system. There's currently no way to make a Ridinghood eBAT. In fact, I haven't tested eBAT support in this commit. I also haven't tested NEON, but at least ARCH_32 works on Intel.
