<kvm.h> is self-sufficient again. Moved typedefs and forward struct declarations out of __BEGIN_DECLS/ __END_DECLS. Don't comment out the prototype for kvm_uread(). This was a 4 year old kludge for previous breakage of self-sufficiency. The prototypwe was broken instead. Fixed bitrot (const poisoning) in the type of kvm_uread(). Fixed order of the declaration of kvm_uread().
