For read-only containers set to create tmpfs filesystems over
/run and other common destinations, we were incorrectly setting
mount options, resulting in duplicate mount options.

If I mount, say, /usr/bin into my container - I expect to be able
to run the executables in that mount. Unconditionally applying
noexec would be a bad idea.
Before my patches to change mount options and allow exec/dev/suid
being set explicitly, we inferred the mount options from where on
the base system the mount originated, and the options it had
there. Implement the same functionality for the new option
handling.
There's a lot of performance left on the table here, but I don't
know that this is ever going to take enough time to make it worth
optimizing.

We already process the options on all tmpfs filesystems during
final addition of mounts to the spec. We don't need to do it
before that in parseVolumes.

Previously, we explicitly set noexec/nosuid/nodev on every mount,
with no ability to disable them. The 'mount' command on Linux
will accept their inverses without complaint, though - 'noexec'
is counteracted by 'exec', 'nosuid' by 'suid', etc. Add support
for passing these options at the command line to disable our
explicit forcing of security options.
This also cleans up mount option handling significantly. We are
still parsing options in more than one place, which isn't good,
but option parsing for bind and tmpfs mounts has been unified.

The initial implementation was far more complicated than necessary.
Strip out the complexities in favor of a simpler and more direct
approach.

This will require a 'podman system renumber' after being applied
to get lock numbers for existing volumes.
Add the DB backend code for rewriting volume configs and use it
for updating lock numbers as part of 'system renumber'.

Decompose() returns an error defined in CNI which has been removed
upstream because it had no in-tree (eg in CNI) users.

when performing an image build over a varlink connection, we should
clean up tmp files that are a result of sending the file to the host and
untarring it for the build.

Specifically pertaining to executing tests in google cloud, there are
default, pre-allocated class-a subnetworks for each region (data-center).
Each includes a gateway using a `.1` LSB and all are routable from other
regions in google cloud via these gateways.
Because the default CNI configuration also utilizes class-a subnetworks,
this creates the possibility for IPv4 address-space clashes. Since the
default regional cloud subnets are pre-defined/known, preventing clashes
can be accomplished by seeding these subnets in a dummy CNI configuration.
The default behavior of podman is to grab the highest priority CNI
configuration. Name the dummy config. appropriate so it always loads
last. Also name the bridge itself with an obvious name `do-not-use`,
such that any related testing errors should be easier to debug.
Also:
* Minor cleanup of `install_test_configs()`
* Move install_test_configs in `setup_environment.sh` to after possible
run of `remove_packaged_podman_files()` because that also strips out
`/etc/cni/net.d/87-podman-bridge.conflist`.

podman cp has had some unexpected bugs, and still has
some surprising behavior. It looks like this part of
the code is fragile. Add tests to try to prevent
future breakages.
Note that two of the new tests are disabled (skipped)
until #3829 gets fixed.

Both Podman and CRI-O set up CNI bridges with the name 'cni0'. If
both our CNI conflist and the CRI-O conflist are installed,
whoever runs first will win - that is, they will configure the
bridge, and everyone will use it. Problem: the CRI-O CNI config
conflicts with ours and results in containers with no networking.
Solution: rename our bridge so we don't conflict with CRI-O.
At the same time, hit our IPAM configuration. The current version
was an older format in danger of deprecation. The new format is
documented at [1].
Finally, fix indentation for the entire file.

Update the CNI configuration instructions to line up with
the changes introduced in #3868. Also do a bit less documentation
of the configuration and point to the GitHub project so we won't
get out of sync in the future.
