Remove openssl imports from public header files

Currently, protocol.h includes openssl/curve25519.h, meaning code which
wishes to link against a roughtime library must also have the OpenSSL/
BoringSSL source available. That's an unneeded dependency.

This CL introduces three new symbols for the Ed25519 public key, private
key, and signature lengths need in the headers and adds static asserts
in protocol.cc to pin them to the libcrypto values.
