crypto: move built-in D3DES implementation into crypto/

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.
