This fixes the issue with our copy_stream where non-pipe
descriptors with the O_NONBLOCK flag set were not handled
correctly. Like IO.copy_stream in Ruby 1.9, our
IO::Splice.copy_stream will _always_ block until IO is available
(or raise if there are errors).
IO::Splice.copy_stream now closes all file descriptors that were
opened within the method, reducing pressure on the garbage
There are also new singleton convenience methods:
* IO::Splice.full - blocks and splices the full amount
* IO::Splice.partial - blocks until something is spliceable
They are used internally to implement IO::Splice.copy_stream,
but may also be useful to end users.
