Title: Survive compilation with more GCC warnings enabled

To import this code into Tor, I need to survive warnings about
implicitly narrowing 64-bit to 32-bit types, warnings about not being
able to declare variables in the middle of C89 blocks, and warnings
about not having a prototype for curve25519_donna() before defining
it.

This patch doesn't actually enable more warnings; it just makes the
code survive them.
