Kevent feature request for aio_sendfile().


Suparna Bhattacharya (IBM) has requested new feature in the asynchronous file sending syscall - header pointer, which will be put into socket queue before file's data.
Although Linux syscall overhead is extremely small compared to other Unix systems, it is still not zero, so since I already "optimized" (i.e. removed) open() call in aio_sendfile_path(), I think things will not became worse if I will put there header pointer and length too.
I plan to release new kevent version after M-on-N threading model implementation with this feature implemented.
