This should hopefully make it easier to distinguish it from
std::io::IoSliceMut.

IoSliceMut doesn't currently provide a way to access the fields of the
internal iovec. Additionally, the as_iobuf() method returns a copy of
the iovec rather than a reference, which can cause hard to diagnose
issues.
Replace the as_iobuf() method with implementations of the AsRef and
AsMut traits. This should also make it easier to hide these impls behind
a `#[cfg(unix)]` in the future.

Pointers in rust don't implement Send or Sync and so any struct that
contains a raw pointer doesn't implement those traits either. However,
there's nothing inherently unsafe about sending a pointer across thread
boundaries. The only unsafety comes from actually de-referencing the
pointer, which already requires an unsafe block.
Explicitly implement Send + Sync for IoSliceMut since the iovec
internally holds a *mut c_void, which prevents those traits from being
auto-implemented. Send + Sync is also implemented by
std::io::IoSliceMut, which is almost exactly the same as our IoSliceMut,
so that can provide some additional reassurance that this is safe.
Also add a missing copyright header in the file.

Fix following warnings so that cargo clippy passes under sys_utils:
* new_without_default
* wrong_self_convention
* or_fun_call
* comparison_chain
Note that we still have warnings on other targets such as --tests.

Switches from using libc::iovec directly to using our own IoSliceMut.
This also renames IntoIovec to IntoIobuf, along with the associated
methods. Effectively this pushes conversion into iovec closer to
where it is used.
