7a11ed5a77 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.

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

60bfa305a8 Add ONBUILD support to --change
Return types had to change a bit for this, but since we can wrap
the old v1.ImageConfig, changes are overall not particularly bad.

At present, I believe this only works with commit, not import.
This matches how things were before we changed to the new parsing
so I think this is fine.

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.

This requires updating all import paths throughout, and a matching

I can't figure out the reason for go.mod tracking

((go mod graph) lists it as a direct dependency of libpod, but
(go list -json -m all) lists it as an indirect dependency),
but at least looking at the vendor subdirectory, it doesn't seem
to be actually used in the built binaries.
