Avi Kivity 39db54a758 Merge "Use seastar::with_file_close_on_failure in commitlog" from Benny ...

"
`close_on_failure` was committed to seastar so use
the library version.

This requires making the lambda function passed to
it nothrow move constructible, so this series also
makes db::commitlog::descriptor move constructor noexcept
and changes allocate_segment_ex and segment::segment
to get a descriptor by value rather than by reference.

Test: unit(dev), commitlog_test(debug)
"

  commitlog: descriptor: make nothrow move constructible
