David Gibson 0b5136c7ce Make error message matching in 030-run.bats less fragile
Amongst other things 030-run.bats checks for sensible error messages when
attempting a "podman run" with a non-existent or inaccessible path.  It
checks for these messages, which come from the low-level runtime, in a lot
of detail, including separate versions for runc and crun.  This is fragile
in several ways:
  * It's likely to fail if using a runtime other than crun or runc
  * It relies on detecting whether the runtime is crun vs. runc using the
    path, which could fail if the binary has been named something unusual
  * It will break if crun or runc ever alter their error message (even if
    it's just changing case)

This replaces the checked versions with a much more accepting regex which
will work for both the runc and crun messages, while still looking for the
essential pieces.  This isn't guaranteed to work with other runtimes, but
it's much more likely to.

support advanced network configuration via cli
Rework the --network parse logic to support multiple networks with
specific network configuration settings.
--network can now be set multiple times. For bridge network mode the
following options have been added:
  - **alias=name**: Add network-scoped alias for the container.
  - **ip=IPv4**: Specify a static ipv4 address for this container.
  - **ip=IPv6**: Specify a static ipv6 address for this container.
  - **mac=MAC**: Specify a static mac address address for this container.
  - **interface_name**: Specify a name for the created network interface inside the container.

So now you can set --network bridge:ip=10.88.0.10,mac=44:33:22:11:00:99
for the default bridge network as well as for network names.
This is better than using --ip because we can set the ip per network
without any confusion which network the ip address should be assigned
to.
The --ip, --mac-address and --network-alias options are still supported
but --ip or --mac-address can only be set when only one network is set.
This limitation already existed previously.

The ability to specify a custom network interface name is new

libpod: fix race when closing STDIN
There is a race where `conn.Close()` was called before `conn.CloseWrite()`.
In this case `CloseWrite` will fail and an useless error is printed. To
fix this we move the the `CloseWrite()` call to the same goroutine to
remove the race. This ensures that `CloseWrite()` is called before
`Close()` and never afterwards.
Also fixed podman-remote run where the STDIN was never was closed.
This is causing flakes in CI testing.

Ed Santiago bf94ebf423 System tests: tighten 'is' operator
Fix day-one sloppiness: when I first wrote this framework
it compared strings using 'expr', not '=', to be more
forgiving of extra cruft in output. This was a bad decision.
It means that warnings or additional text are ignored:

    is "all is ok, NOT!"  "all is ok"  <-- this would pass

Solution: tighten up the 'is' check. Use '=' (direct
compare) first. If it fails, look for wild cards ('*')
or character classes ('[') in the expect string. If
so, and only then, use 'expr'. And, thanks to a clever
suggestion from Luap99, include '(using expr)' in the
error message when we do so; this could make it easier
for a developer to understand a string mismatch.

This change exposes a lot of instances in which we weren't
doing proper comparisons. Fix those. Thankfully, there
weren't as many as I'd feared.

Also, and completely unrelated, add '-T' flag to bats
helper, for showing timing results. (I will open this
as a separate PR if requested. I too find it offensive
to jumble together unrelated commits.)

Valentin Rothberg 0f7d54b026 migrate Podman to containers/common/libimage
Migrate the Podman code base over to `common/libimage` which replaces
`libpod/image` and a lot of glue code entirely.

Note that I tried to leave bread crumbs for changed tests.

Miscellaneous changes:

 * Some errors yield different messages which required to alter some
   tests.

 * I fixed some pre-existing issues in the code.  Others were marked as
   `//TODO`s to prevent the PR from exploding.

 * The `NamesHistory` of an image is returned as is from the storage.
   Previously, we did some filtering which I think is undesirable.
   Instead we should return the data as stored in the storage.

 * Touched handlers use the ABI interfaces where possible.

 * Local image resolution: previously Podman would match "foo" on
   "myfoo".  This behaviour has been changed and Podman will now
   only match on repository boundaries such that "foo" would match
   "my/foo" but not "myfoo".  I consider the old behaviour to be a
   bug, at the very least an exotic corner case.

 * Futhermore, "foo:none" does *not* resolve to a local image "foo"
   without tag anymore.  It's a hill I am (almost) willing to die on.

 * `image prune` prints the IDs of pruned images.  Previously, in some
   cases, the names were printed instead.  The API clearly states ID,
   so we should stick to it.

 * Compat endpoint image removal with _force_ deletes the entire not
   only the specified tag.

Valentin Rothberg 821ef6486a fix logic when not creating a workdir
When resolving the workdir of a container, we may need to create unless
the user set it explicitly on the command line.  Otherwise, we just do a

Valentin Rothberg 0f668aa085 workdir presence checks
A container's workdir can be specified via the CLI via `--workdir` and
via an image config with the CLI having precedence.

Since images have a tendency to specify workdirs without necessarily
shipping the paths with the root FS, make sure that Podman creates the
workdir.  When specified via the CLI, do not create the path, but check
for its existence and return a human-friendly error.

NOTE: `crun` is performing a similar check that would yield exit code
127.  With this change, however, Podman performs the check and yields
exit code 126.  Since this is specific to `crun`, I do not consider it
to be a breaking change of Podman.

Podman often reports OCI Runtime does not exist, even if it does
When the OCI Runtime tries to set certain settings in cgroups
it can get the error "no such file or directory",  the wrapper
ends up reporting a bogus error like:

{"cause":"OCI runtime command not found error","message":"open io.max: No such file or directory: OCI runtime command not found error","response":500}
