Add an opaque pointer for vhost IOTLB. And introduce
vhost_iotlb_add_range_ctx() to accept it.

Trivial change for the vhost_iotlb_del_range() documentation,
fixing the function name in the comment block.
Discovered with `make C=2 M=drivers/vhost`:
../drivers/vhost/iotlb.c:92: warning: expecting prototype for vring_iotlb_del_range(). Prototype was for vhost_iotlb_del_range() instead

Fix documentation to match actual function prototypes
"end" used instead of "last". Fix that.

This patch factors out IOTLB into a dedicated module in order to be
reused by other modules like vringh. User may choose to enable the
automatic retiring by specifying VHOST_IOTLB_FLAG_RETIRE flag to fit
for the case of vhost device IOTLB implementation.
