0427fa42ee Rename enif_crypto_ to enacl_crypto_ 
This is a better name which spits stuff appropriately.

We don't pollute the enif_ namespace.

The name of the generichash function was wrong, so it was not possible to find it when
loading the NIF.

b7533d3b9c Release resources under failure 
sign and generichash failed to release their resources under failure.

This can lead to subtle memory leaks in the very unlikely event
we can't initialize.

1121321573 Generic hash state needs to be 64-byte aligned 
At least according to:
  https://libsodium.gitbook.io/doc/hashing/generic_hashing

We noticed crashes when it was not 16-byte aligned - probably is
architecture dependent. This makes the safe choice and always 64-byte
align it.

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.

bf4d61680c Change size_t variables to unsigned int's. 
These variables are being initialized via calls to `enif_get_uint`,
so it's safer to declare them as unsigned int's rather than size_t's.
Their being used in calls to `enif_alloc_binary`, which takes a size_t
as its size.
However, the resulting ErlNifBinary keeps its size as an unsigned int,
so asking for a size that's an unsigned int should be safe.

This would be problematic in the case where sizeof(size_t) <
sizeof(unsigned), which would mean we're getting fewer bytes allocated
than expected.
Perhaps an explicit check for, for example, `hashSize > MAX_SIZE` would
be good here?
