The io.Writer contract requires that Write writes all available
bytes and does not return short writes. This causes errors with
io.Copy, since our own Write interface does not have this same
contract.

sendfile can be called for a big range and it can require significant
amount of time to process it, so we need to handle task interrupts in
this system call.

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.

RootFromContext can return a dirent with reference taken, or nil. We must call
DecRef if (and only if) a real dirent is returned.

FIOASYNC and friends are used to send signals when a file is ready for IO.
This may or may not be needed by Nginx. While Nginx does use it, it is unclear
if the code that uses it has any effect.
