...safer, too: the big change is using 'mapfile' to split
multiline strings; this preserves empty lines, making it
easy to see spurious (or missing) blank lines in output.
Another change is to indent the expected-output string
consistently, for readability.
Then, to handle \r (CR) and other control characters, use
bash %q to format special chars. But %q makes\ it\ hard\ to
read\ lines\ with\ spaces, so strip off those backslashes.
This makes assert() much larger and uglier, but this is
code that shouldn't be touched often.
Finally, because these are big changes to critical code,
write a complicated regression test suite for assert().

The main helpers.bash file is rather bloated and it's difficult to
find stuff there. Move networking functions to their own helper
file.
While at it, apply a consistent style, and rearrange logically
related functions into sections.

Using bash /dev/tcp/ pseudo-device files to probe for bound ports has
indeed the advantage of simplicity, but comes with a few drawbacks:
- it will actually send data to unsuspecting services that might be
running in the same network namespace as the tests, possibly
causing unwanted interactions
- it doesn't allow for UDP probing
- it makes it impossible to clearly distinguish between different
address bindings
Replace that approach with a new helper, port_is_bound(), that uses
procfs entries at /proc/net to detect bound ports, without the need
for active probing.
We can now implement optional parameters in callers, to check if a
port if free for binding to a given address, including any IPv4
(0.0.0.0) or any IPv6 (::0) address, and for a given protocol, TCP
or UDP.
Extend random_free_port() and random_free_port_range() to support
that.
The implementation of one function in the file
test/system/helpers.bash, namely ipv6_to_procfs(), and the
implementation of the corresponding own test, delimited by the
markers "# BEGIN ipv6_to_procfs" and "# END ipv6_to_procfs" in the
file test/system/helpers.c was provided, on the public forum at:
https://github.com/containers/podman/pull/16141

include them in this code submission.

The parse_table() helper has until now dumbly split lines
on every single '|' character. This prevents us from running
simple tests such as 'cgroupManager: (systemd|cgroupfs)'.
We now use an ugly but robust sed expression to split
on '|' but *only* when surrounded by spaces and/or beginning
or end of line. This is safe because, for readability, all
tables already keep the '|' symbols well separated from
table content.
Add tests. And, the whole reason behind this, add
an actual real test for cgroupManager and cgroupVersion.

It's not possible to run any of the scripts on distributions which do
have `bash` not in `/bin`. This is being fixed by using `/usr/bin/env
bash` instead.

Tests for #7094, in which symlinks in a volume would
cause chown errors and nonrunnable containers.
Tests for environment variable precedence, now
include --env-host and proxy settings
Fix a bug caught by covscan in helpers.t ('source'
path would fail if path included spaces).
Fix podman-run man page: it was incorrect in stating
precedence between in-image environment and --env-host.
Fixes: #7099

- Issue #6735 : problem with multiple namespaces; confirms
combinations of --userns=keep-id, --privileged, --user=XX
- Issue #6829 : --userns=keep-id will add a /etc/passwd entry
- Issue #6593 : podman exec, with --userns=keep-id, errors
(test is currently skipped because issue remains live)
...and, addendum: add new helper function, remove_same_dev_warning.
Some CI systems issue a warning on podman run --privileged:
WARNING: The same type, major and minor should not be used for multiple devices.
We already had special-case code to ignore than in the SELinux
test, but now we're seeing it in the new run tests I added, so
I've refactored the "ignore this warning" code and written
tests for the removal code.

Initial attempt at writing a framework for podman system tests.
The idea is to define a useful set of primitives that will
make it easy to write actual tests and to interpret results
of failing ones.
This is a proof-of-concept right now; only a small number of
tests, by no means comprehensive. I am requesting review in
order to find showstopper problems: reasons why this approach
cannot work. Should there be none, we can work toward running
these as gating tests for Fedora and RHEL8.
