Michael Pratt 704f9610f3 Require pread/pwrite for splice file offsets
If there is an offset, the file must support pread/pwrite. See
fs/splice.c:do_splice.

Adin Scannell 9cdae51fec Add basic plumbing for splice and stub implementation.
This does not actually implement an efficient splice or sendfile. Rather, it
adds a generic plumbing to the file internals so that this can be added. All
file implementations use the stub fileutil.NoSplice implementation, which
causes sendfile and splice to fall back to an internal copy.

A basic splice system call interface is added, along with a test.
