To prepare for a generic internal cipher API, move the built-in D3DES implementation into the crypto/ directory. This is not in fact a normal D3DES implementation, it is D3DES with double & triple length modes removed, and the key bytes in reversed bit order. IOW it is crippled specifically for the "benefit" of RFB, so call the new files desrfb.c instead of d3des.c to make it clear that it isn't a generally useful impl. Signed-off-by: Daniel P.
