Refactor handling of input files
We now try much harder to avoid opening input file more than once by
reusing the file descriptor in more cases.
We no longer call posix_fadvise() with POSIX_FADV_NOREUSE under Linux,
since it's still not implemented there.
We now only call posix_fadvise() with POSIX_FADV_DONTNEED under Linux,
and we do it right before we close the file descriptor.
(cherry picked from commit 67717d56f346af445a7df3781438e11a42ab504e)
