Robert Watson 89e9e6e7c5 In sendfile(), use the vn_rdwr() helper function, rather than manually 
constructing a struct aio and invoking VOP_READ() directly.  This cleans
up the code a little, but also has the advantage of making sure almost
all vnode read/write access in the kernel goes through the helper
function, meaning that instrumentation of that helper function can impact
almost all relevant read/write operations.  In this case, it permits us
to put MAC hooks into vn_rdwr() and not modify uipc_syscalls.c (yet).

In general, if helper vn_*() functions exist, they should be used in
preference to direct VOP's in system call service code.
