d49d7e8d4f pwhash: don't enforce the same limits for argon2i and argon2id 
Fixes #606

Also, keep enforcing a minimum number of iterations to create argon2i
hashes, but relax that restriction for verification, as it can be
useful to migrate from hashes made using other libraries.

2542367c2d secretstream: set the initial counter to 1 
Avoids using the first block for two different purposes, and will be more
consistent with the AES-based version.

This breaks backwards compatibility, but better do it now that most distro are
still shipping < 1.0.14, that no applications seem to be already using that new
API, and that there will be an update to the library major due to the aes128ctr
removal.

0af31aeb26 Fill the max output buffer size in sodium_bin2base64() 
Unlike hex encoding, due to optional padding, computing the correct size is
not straightforward. Ensuring that the string ends with `\0` is fine, but
if the size is not exact, some unrelated data might be send around by the
application. So, zero it to be safe.

to detect this and ignore tests depending on working signal handlers.

1fd6a4bfc2 Replace which with command for portability (#542) 
The `which` command is not part of the posix standard and not available
in some environments.  The `command` command is part of the posix
standard and well supported.

See https://unix.stackexchange.com/q/85249 for a discussion about the
use of `command` instead of `which`.

If a system had `libtool` but not `which`, the build process would issue
an erroneous error stating:

    libtool is required, but wasn't found on this system

Switching to `command` corrects this problem.

70c2796ae5 + crypto_kdf high-level API 
This is a common need, and people end up reimplementing HKDF.

So, add a crypto_kdf() API similiar to libhydrogen's. The later has a
higher limit for the output length using BLAKE2X if required.

We can implement the same strategy later in libsodium if needed.

e0150faf56 Always zero the argon2 output buffer prior to doing anything 
This is consistent with what we are doing with scrypt.
On error/misuse, the buffer is zeroed; this may prevent bugs with
reused/invalid buffers.
