* build with varlink
* build podman-remote
* build podman-remote-darwin

integration of healthcheck into create and run as well as inspect.
healthcheck enhancements are as follows:
* add the following options to create|run so that non-docker images can
define healthchecks at the container level.
* --healthcheck-command
* --healthcheck-retries
* --healthcheck-interval
* --healthcheck-start-period
* podman create|run --healthcheck-command=none disables healthcheck as
described by an image.
* the healthcheck itself and the healthcheck "history" can now be
observed in podman inspect
* added the wiring for healthcheck history which logs the health history
of the container, the current failed streak attempts, and log entries
for the last five attempts which themselves have start and stop times,
result, and a 500 character truncated (if needed) log of stderr/stdout.
The timings themselves are not implemented in this PR but will be in
future enablement (i.e. next).

In lipod, we now log major events that occurr. These events
can be displayed using the `podman events` command. Each
event contains:
* Type (container, image, volume, pod...)
* Status (create, rm, stop, kill, ....)
* Timestamp in RFC3339Nano format
* Name (if applicable)
* Image (if applicable)
The format of the event and the varlink endpoint are to not
be considered stable until cockpit has done its enablement.

Currently if you turn on --net=host on a rootless container
and have selinux-policy installed in the image, tools running with
SELinux will see that the system is SELinux enabled in rootless mode.
This patch mounts a tmpfs over /sys/fs/selinux blocking this behaviour.
This patch also fixes the fact that if you shared --pid=host we were not
masking over certin /proc paths.

we were playing safe and not allowed any container to have less than
65536 mappings. There are a couple of reasons to change it:
- it blocked libpod to work in an environment where
newuidmap/newgidmap are not available, or not configured.
- not allowed to use different partitions of subuids, where each user
has less than 65536 ids available.
Hopefully this change in containers/storage:
https://github.com/containers/storage/pull/303
will make error clearers if there are not enough IDs for the image
that is being used.

The Golang standard library implementation of RFC3339Nano will
trim trailing 0s from the nanoseconds portion of timestamps. This
is undesirable for lining everything up nicely during terminal
output. As the Golang developers have not seen fit to give us a
better way, use the one that was proposed on the issue tracker
but rejected.

When we log time timestamps, don't print a new timestamp for each
input - instead, print one at the start of every line, and then
wait until we hit a newline to print a new timestamp.
This still doesn't exactly mirror the Docker behavior (they don't
print until they receive an entire line, while we print any time
the logs file is appended to - so you can see partial lines being
typed in our system). Also, timestamps are recorded as the start
of a line being typed, as opposed to when the enter key is
pressed (on Docker).
(Worth noting that, while characters are printed as they are
typed, logs does respect the backspace key - so you'll also see
them disappear as the person typing realizes they've made a
mistake and retypes their command).
This is the closest we can get to Docker without major surgery on
the Kubernetes log-printing library, so I'm content to call this
an adequate solution.

When writing logs with timestamps to the terminal, ensure that
each line is newline-terminated, so we don't end up with an
unreadable mess with timestamps interspersed with the actual
content being displayed.

When using a user namespace, we create the mount point under
`mountPrefix` so that the uid != 0 can access that directory.
Change the addFIPSModeSecret code to honor that, and also ensure we
are creating the directories with the right ownership.

If the source of a bind mount has any of nosuid, noexec or nodev, be
sure to propagate them to the bind mount so that when runc tries to
