Robb Manes 90066af62e Calculate device major/minor using bitshift
Previously, devices with a major/minor number >256 would fail to be
detected.  Switch to using bitwise conversion (similar to
sys/sysmacros in C).

volume: add support for non-volatile upperdir,workdir for overlay volumes
Often users want their overlayed volumes to be `non-volatile` in nature
that means that same `upper` dir can be re-used by one or more
containers but overall of nature of volumes still have to be `overlay`
so work done is still on a overlay not on the actual volume.

Following PR adds support for more advanced options i.e custom `workdir`
and `upperdir` for overlayed volumes. So that users can re-use `workdir`
and `upperdir` across new containers as well.

Usage
```console

$ podman run -it -v myvol:/data:O,upperdir=/path/persistant/upper,workdir=/path/persistant/work alpine sh

Allow users to add host user accounts to /etc/passwd
Some containers require certain user account(s) to exist within the

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.

```
According to the Docker docs, the consistency option should be ignored on Linux.

the possible values are 'cached', 'delegated', and 'consistent', but they should be ignored equally.

This is a widely used option in scripts run by developer machines, as this makes file I/O less horribly slow on MacOS.

Matthew Heon ab88632835 Use Libpod tmpdir for pause path
Previously, we always computed pause path from the Rootless
runtime directory. Problem: this does not match the behavior of
Libpod when the directory changes. Libpod will continue to use
the previous directory, cached in the database; Pause pidfiles
will swap to the new path. This is problematic when the directory
needs to exist to write the pidfile, and Libpod is what creates
the directory.

There are two potential solutions - allow the pause pidfile to
move and just make the directory when we want to write it, or use
the cached Libpod paths for a guaranteed location. This patch
does the second, because it seems safer - we will never miss a
previously-existing pidfile because the location is now
consistent.

Fixes #8539

Podman is committed to inclusivity, a core value of open source. Historically, there have been technology terms that are problematic and divisive, and should be changed. We are currently taking time to audit our repository in order to eliminate such terminology, and replace it with more inclusive terms. We are starting where we can, with our own code, comments, and documentation. However, such terms may be used in dependencies, and must be used in our repositories at the current moment for compatibility. Podman will change these terms in our repo as soon as new and better terminology is available to us via our dependencies.

libpod: fix --userns=keep-id with big UIDs
when creating a keep-id namespace, we split the original user
namespace in:

inner ns | outer ns  | size:
0        | 1         | ID
ID       | 0         | 1
ID+1     | ID+1      | availableIds - ID

When the user ID is bigger than the number of available
subuids/subgids we fail to create the user namespace because the first
slice is bigger than the available number of IDs and the third one has
a negative size.

Fix it by not using more than the available number of IDs in the first
slice and creating the third one only if there are other IDs left.

When the user ID is bigger than the number of additional IDs, there
will be a gap between the two mappings so the IDs between the maximum
additional ID and the user ID won't be present inside of the
namespace.

Ed Santiago 40f55ca3fe signal parsing - better input validation
The helper function we use for signal name mapping does not
check for negative numbers nor invalid (too-high) ones. This
can yield unexpected error messages:

   # podman kill -s -1 foo
   ERRO[0000] unknown signal "18446744073709551615"

This PR introduces a small wrapper for it that:

  1) Strips off a leading dash, allowing '-1' or '-HUP'
     as valid inputs; and
  2) Rejects numbers <1 or >64 (SIGRTMAX)

Also adds a test suite checking signal handling as well as
ensuring that invalid signals are rejected by the command line.

Fixes: #4746

Jonathan Dieter b3014c1c69 Return empty runtime directory if we're not rootless
Currently, we return a runtime directory of the form
`/run/user/<uid>`, even when running as root.  Depending on configuration,
that directory may be deleted when the user logs out, which is quite
awkward when the container is started as a systemd service and then
someone logs in and out as root.

This patch fixes the problem by returning an empty runtime directory if the
container is being started by root.  The runtime should automatically use
the default runtime directory (`/run/crun` when crun is used), which should
be accessible to root.

Tested in Fedora 31 by running containers under both root and a regular
user.  State for root containers is stored in `/run/crun`, while state for
rootless containers is in `/run/user/<uid>/crun`.

Matthew Heon 001d06d7f6 Completely rework --change parsing
The way we were trying to parse was very broken. I originally
attempted to use Buildah's Dockerfile parser here, but dealing
with it (and convincing it to accept only a limited subset, and
only one instruction at a time) was challenging, so I rewrote a
subset of Dockerfile parsing. This should handle most common
cases well, though there are definitely unhandled edge cases for
ENV and LABEL.

Matthew Heon 5bdd97f77f Set base mount options for bind mounts from base system
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.

Matthew Heon 02264d597f Add support for 'exec', 'suid', 'dev' mount flags
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.
