	Nettle's des functions.

	* New name mangling, to reduce the risk of link collisions. All
	functions (except memxor) now use a nettle_ or _nettle prefix when
	seen by the linker. For most functions, the header file that
	declares a function also use #define to provide a shorter more
	readable name without the prefix.
