It makes no sense to forward it, SIGSTOP cannot be handled by
userspace (like SIGKILL) and it didn't do anything before so this just
makes it more explicit.

Instead of catching all signals and then ignoring them inside the loop
again just don't register them in Notify() to begin with.

This is part of a set of changes to port podman to the FreeBSD platform.
The pkg/signal parts are needed to enable ABI mode on FreeBSD. No tests
are needed here because it should be a functional no-op for linux.

There is no good way to recommend labels for podman container runlabel.
Add the missing max-size log option. These are the only documented
options so the completion should not suggest something different.
Add proper --stop-signal completion. It will now complete all supported
signal names both upper and lowercase depending on the user input. Also
it work with and without the SIG prefix.
Fixing the TODOs in this file are more complicated since they describe
bigger features.

Still an unknown number remains but I am running out of patience.
Adding dots is not the best use of my time.

Follow-up to commit (1ad796677e1c). The build on mips is still
failing because SIGWINCH was not defined in the signal pkg.
Also stat_t.Rdev is unit32 on mips so we need to typecast.

The signal SIGSTKFLT does not exists on mips architectures.
Also RTMIN and RTMAX are different.
This code is copied from docker.

To ensure the Windows and OS X remote clients can properly parse
container stop signal (when given as a name e.g. SIGTERM) and
set it in SpecGen, we need access to a list of Linux signal names
and the numbers they map to that is available on non-Linux OSes.
Fortunately, these are ABI constants that are extremely unlikely
to change, so we can just take the existing constant definitions
from the library and use them.
The signal numbers used here are sourced from AMD64, but should
be the same for every architecture that is not Alpha, SPARC,
MIPS, and PA-RISC. So `podman run --stop-signal SIGTTOU` from a
Windows client to a Podman service on a SPARC host will set an
incorrect stop signal, but I don't think this is a large problem.

Add pkg/signal to deal with parts of signal processing and translating
signals from string to numeric representations. The code has been
copied from docker/docker (and attributed with the copyright) but been
reduced to only what libpod needs (on Linux).
