There was a memory problem in the encryption using snow_3g_f8,
so AMF/MME crashed.
To solve this problem, we used the snow-3g encryption library
created as below.
https://github.com/rcatolino/libressl-snow3g
However, it seems that this library cannot be used to create
integrity hash like snow_3g_f8.
So, we decided to keep both snow-3g libraries for the time being.
1. lib/crypt/snow3g* : for INTEGRITY (NIA1, EIA1)
2. lib/crypt/openssl/snow3g* : for ENCRYPTION (NEA1, EEA1)
