Podman adds a few environment variables by default, and
currently there is no way to get rid of them from your container.
This option will allow you to specify which defaults you don't
want.
--unsetenv-all will remove all default environment variables.
Default environment variables can come from podman builtin,
containers.conf or from the container image.

Add new CI check to confirm that links and references
in SEE ALSO sections are properly formatted and that
links are valid (at least in theory: we do no actual
URL fetching to test for 404).
The check is piggybacked into existing xref-helpmsgs-manpages
script. It could conceivably be more elegant to write a
separate tool for this purpose, but I don't wish to duplicate
the logic for finding and reading markdown files.
Script identified various problems, which I fix in this PR:
. missing '**' (asterisks) around some references, or '**'
in the wrong place.
. links pointing to github.com/.../tree/ instead of /blob/
(github redirects those automatically, but I like
consistency)
. a few copy-paste errors, e.g. subgid linking to subuid.

Podman has, for a long time, had an internal concept of
dependency management, used mainly to ensure that pod infra
containers are started before any other container in the pod. We
also have the ability to recursively start these dependencies,
which we use to ensure that `podman start` on a container in a
pod will not fail because the infra container is stopped. We have
not, however, exposed these via the command line until now.
Add a `--requires` flag to `podman run` and `podman create` to
allow users to manually specify dependency containers. These
containers must be running before the container will start. Also,
make recursive starting with `podman start` default so we can
start these containers and their dependencies easily.
