The replaced code is licensed as GPLv2 only unlike the rest of libosmocore which is
GPLv2+
The replacement is adopted from Nettle cryptographic library:

All the files are taken as is with exception of aes-internal.h which was
significantly reduced.
Of course personally I would prefer just to link to Nettle but during the discussing
over irc and ML there's been strong voices against introducing extra dependencies.
