f580f6525b Streamline _open style calls 
Those now return {ok, Msg} or
{error, term()} so you are kind of
forced to match on them. This is
likely to help with correctnes.

7999d08e9d Streamlining of secret and _verify 
The secret key API is now streamlined.

Also, all verify-type functions are
now returning boolean() values.
This makes the API consistent.

e67619a403 Update the naming scheme of AEAD xchacha20... 
Since this AEAD construction variant is an IETF variant, reflect
this in the names of the functions.

This streamlines the API with the libsodium API.

7f857115bb Add aead IETF constructions 
Since the chacha20poly1305 constructions were the IETF variants,
we renamed those so they follow the official library better. While
here, we also fixed the argument order of the files.

bdb4719f6d Fix AEAD parameter order / naming. 
The order of parameters were in the wrong order. Make them equal
to the official order of libsodium.

While here, rename NONCEBYTES to NPUBBYTES so it reflects the
underlying names as well.

Add choice of ops and mem limits to pwhash_str 
It natively checks atoms, which is kinda messy, but it avoids having to
export the libsodium pwhash constants, which is nice.

edd95498d1 Fix pwhash_str* functions. 
The API for pwhash_str returns a cstring in the output buffer. These
are null terminated. However, we return the full buffer as a binary
back to Erlang. This means that we have a buffer with 0'es in the end.

The tests take this buffer and passes it back in as is. Hence all the
tests pass. However, it is conceivable that if we write said buffer to
disk somewhere, we are not going to write those 0's out.

When we then load the ASCII-armored Argon2 string into memory again,
it is not 0-terminated as a cstring should be, and this produces
errors all over the place.

The fix is twofold:

* Return the full buffer to Erlang, but use binary:split/2 to create a
  subbinary with the relevant part.
* Add a 0 in the end of ASCII Argon2 string before passing it to
  libsodium

Since we are looking at pwhashing, and Argon2, we expect the
computational problem to be memory bound. Thus, spending a bit more
work in memory is not going to have any considerable impact on the
speed of this system.

3b9bc848e9 Move functions around. Mark untested functionality. 
A lot of people who pushed functions they missed have not pushed any
kind of test cases for them. To make sure we have test coverage, I've
marked the functions we have under test and the functions we are still
missing tests for.
