[core] multiple decryption keys support

This commit complements the support for multiple signing certificate
support in the metadata files. The use-case is still key roll-over.

The structure LassoServerPrivateData was changed to accomodate multiple
decryption keys, and so:

 xmlSecKey *encryption_private_key

became:

 GList *encryption_private_keys

All uses of this key were replaced by a loop over this list, terminating
with the first key to be able to decrypt the content.

The private key passed to lasso_server_new() or
lasso_server_new_from_buffers() is first added to the list of decryption
keys. Any other call to
lasso_server_set_encryption_private_key_with_password() or
lasso_server_set_encryption_private_key() will add a new key to the
list.
