Due to the fact that roles may be instantiated with different sets of
params (multiple inclusions of the same role or via role dependencies),
simply tracking notified handlers by name does not work. This patch
changes the way we track handler notifications by using the handler
object itself instead of just the name, allowing for multiple internal
instances. Normally this would be bad, but we also modify the way we
search for handlers by first looking at the notifying tasks dependency
chain (ensuring that roles find their own handlers first) and then at
the main list of handlers, using the first match it finds.
This patch also modifies the way we setup the internal list of handlers,
which should allow us to correctly identify if a notified handler exists
more easily.

This makes it so that table columns break by word instead of in between words. It also sets the minimum width of a column in the table to 100px, and makes tables horizontally scrollable on small screen sizes.
This makes Ansible no longer set LC_ALL for remote systems. It is up to
the individual modules to set LC_ALL if they need it for screenscraping
the output from a program.
This is the 2.2 followup for #15138
Problem: When setting the file permissions on the remote server for
unprivileged users ansible expects that a chown will fail for unprivileged
users. For some systems (e.g. HP-UX) this is not the case.
Solution: Change the order how ansible sets the remote permissions.
* If the remote_user sudo's to an unprivileged user then we attempt to
grant the unprivileged user access via file system acls.
* If granting file system acls fails we try to change the owner of the
file with chown which only works in case the remote_user is privileged
or the remote systems allows chown calls by unprivileged users (e.g.
HP-UX)
* If the chown fails we can set the file to be world readable so that
the second unprivileged user can read the file. Since this could allow
other users to get access to private information we only do this
ansible is configured with "allow_world_readable_tmpfiles" in the
ansible.cfg
When the PYTHONPATH is an empty string python will treat it as though
the cwd is in the PYTHONPATH. This can be undesirable. So make sure we
delete PYTHONPATH from the environment altgether in this case.

- Reduce image size by skipping weak package references.
- Consolidate and sort packages to install.
- Improve consistency between versions.
- Combine yum/dnf install and clean to avoid unwanted caching.
- Don't update existing packages from base image unnecessarily.
