Add Chacha20-Poly1305, AES128-GCM and AES256-GCM support (#93)
* Add Chacha20-Poly1305 authenticated encryption
* Add general AEAD approach.
* Add [email protected] algo using LibTomCrypt chacha and
poly1305 routines.
Chacha20-Poly1305 is generally faster than AES256 on CPU w/o dedicated
AES instructions, having the same key size.
Compiling in will add ~5,5kB to binary size on x86-64.

* Add AES128-GCM and AES256-GCM authenticated encryption
* Add general AES-GCM mode.
* Add [email protected] and [email protected] algo using
LibTomCrypt gcm routines.
AES-GCM is combination of AES CTR mode and GHASH, slower than AES-CTR on
CPU w/o dedicated AES/GHASH instructions therefore disabled by default.
Compiling in will add ~6kB to binary size on x86-64.
