Add Swift binding

bump ABI version

Before commit 5e78398c (Added ABI Version Number, and properly handle
it for Linux and Darwin) the library was installed as `libargon2.so`,
though the soname was `libargon2.so.0`. Actually installing a package
with that file makes `ldconfig` create a symbolic link matching the
soname. That file does not  belong to the package and is not managed by
the package manager.

Building a package from current git master results in the library file
`libargon2.so.0` being included in the package. That conflicts with the
file formerly created by `ldconfig`.

So bump the ABI version for a conflict-free transition to current code.

Remove dependency of inttypes.h

Add AVX-512F optimizations

Not to be confused with the ruby binding :)

Don't include 'clean' target in 'make all' to fix parallel builds

add support for fine-grained memory setting

Allow null character in password for cli tool

correct spelling mistake

Fixed comment t_cost value according to t_cost value in code

Fix up documentation for argon2i_hash_raw

Add link to another python binding: porridge

So far the only python binding that enables keyed hashing.

It doesn't allocate the memory at @hash!
