25519 support in openssl about gamenetworkingsockets HOT 4 CLOSED

This is now implemented! It will automatically use OpenSSL if available, and fall back to building with the reference implementations in src/external/ if not.

Please take console and mobile platforms into consideration with these changes. I'm not sure what kind of restrictions they have over crypto but it may require using their crypto libraries? I do know they require it to varying degrees for basically all communication at this point.

Edit: Oh, the next tab I opened: #45 👍

Refactored some stuff, should be much more straightforward to do this now.

These functions would be relevant.
https://www.openssl.org/docs/man1.1.1/man3/EVP_PKEY_get_raw_private_key.html

This means we would require OpenSSL 1.1. (Or we could support older OpenSSL, using the existing Donna support? I kind of wanna delete all that code, though.)

Welp, I implemented all the functions in crypto_25519_openssl.cpp, but it's not working. EVP_PKEY_get_raw_public_key is failing. I need to actually step into OpenSSL, and I don't want to go through the work to get all that setup right now. I need to go back to actually shipping this in Steam.

If anybody else wants to poke at this, go for it!

I'll come back to this later.
