[xmlsec] Loading a DER-encoded certificate

I used to write code when systems did not like 8bit which was used for 
parity check.
In most cases, this problem is gone by now but I still see such problems 
time to time
(for example, you noticed one today --> fopen("rb") :) ). I have never 
had problems
with reading PEM files and this is the main reasons why I prefer base64 
encoded PEM files :)

Well, if you can wait a couple days I can write a function for reading 
DER certificates by myself
(and include it in xmlsec). Or you can do it yourself, it's a 30 minutes 
exercise :)
