virtio, vhost: new device, fixes, speedups

Browse source 
This includes the new virtio crypto device, and fixes all over the
 place.  In particular enabling endian-ness checks for sparse builds
 found some bugs which this fixes.  And it appears that everyone is in
 agreement that disabling endian-ness sparse checks shouldn't be
 necessary any longer.
 
 So this enables them for everyone, and drops __CHECK_ENDIAN__
 and __bitwise__ APIs.
 
 IRQ handling in virtio has been refactored somewhat, the
 larger switch to IRQ_SHARED will have to wait as
 it proved too aggressive.
