Allow to assign multiple certificates to a single private ke

[scop]

many certificates can be issued on a single public key.

portecle makes a strong association of one public with
one private key.

When for example exporting to a pfx that association is
taken.

Attached an example where a second certificate with the
same modulus and exponent is present.

RFEs:
1) upon certificate import detect certificates with the
same public key
2) upon certificate import detect the corresponding
private key
3) allow establish a flexible 1:n relation between the
private key and its corresponding certificates
