[xmlsec] MS Crypto API support

[Aleksey Sanin]

Olger,

I've created "include/xmlsec/skeleton" and "src/skeleton" folders with
minimal set of functions that needs to be implemented by an xmlsec-<crypto>
library. I would appreciate if you can try to use these skeleton files
and report any problem you encounter.

Thank you in advance,
Aleksey
