Align on a single CMake style. We currently write a mix of "if (FOO)" and "if(FOO)". While the former looks more like a usual language, CMake believes everything, even "if" and "else", is just a really really funny function call (a "command"). We should pick something for consistency. Upstream CMake writes "if(FOO)", so go with that one.

Add NEON implementation of curve25519. Nexus 7 goes from 1002.8 ops/sec to 4704.8 at a cost of 10KB of code. (It'll actually save code if built with -mfpu=neon because then the generic version can be discarded by the compiler.)

Include 'asm' in the name of X25519 asm sources. Some build systems don't like two targets with the same base name and the curve25519 code had x25519-x86_64.[Sc].

Add SPAKE2 over Ed25519. SPAKE2 is a password-authenticated key exchange. This implementation is over the twisted Edwards curve Ed25519, and uses SHA-512 as the hash primitive.
