use O_DIRECT for all ReadFileStream (#13324)
This PR also removes #13312 to ensure
that we can use a better mechanism to
handle page-cache, using O_DIRECT
even for Range GETs.

use fadvise to control Linux page-cache (#13312)
This PR brings two optimizations mainly
for page-cache build-up and how to avoid
getting OOM killed in the process. Although
these memories are reclaimable Linux is not
fast enough to reclaim them as needed on a
very busy system. fadvise is a system call
implemented in Linux to advise page-cache to
avoid overload as we get significant amount
of requests on the server.

- FADV_SEQUENTIAL tells that all I/O from now
  is going to be sequential, allowing for more
  resposive throughput.

- FADV_NOREUSE tells kernel to start removing
  things for this 'fd' from page-cache.

rename all remaining packages to internal/ (#12418)
This is to ensure that there are no projects
that try to import `minio/minio/pkg` into
their own repo. Any such common packages should
go to `https://github.com/minio/pkg`
