we were previously closing as many FDs as they were open when we first
started Podman in the range (3-MAX-FD). This would cause issues if
there were empty intervals, as these FDs are later on used by the
Golang runtime. Store exactly what FDs were first open in a fd_set,
so that we can close exactly the FDs that were open at startup.

podman system prune would leave pods be, and not prune them if they were stopped.
Fix this by adding a `podman pod prune` command that prunes stopped pods similarly to containers.

do not try to use ctr if there was an error. It fixes a segfault when
there is already a container with the same name.

we were previously proxying all the signals, but doing that for
SIGTSTP prevented the main process to be stopped by the tty.

Fixes the ability to run (create,start) a container and attach to its
console correctly. We can now also exit from the console without
hanging the remote client.

Also, you can now podman-remote run -it. There are some bugs that need
to be ironed out but I would prefer to merge this so we can make both
progress on start and exec as well as the bugs.
* when doing podman-remote run -it foo /bin/bash, you have to press
enter to get the prompt to display. with the localized podman, we had to
teach it connect to the console first and then start the container so we
did not miss anything.
* when executing "exit" in the console, we get a hard lockup likely
because nobody knows what to do.
* custom detach keys are not supported
* podman-remote run -it alpine ls does not currently work. only
dropping to a shell works.

Don't sort OCI hooks using the locale collation order; it does not
make sense for the same system-wide directory to be interpreted differently
depending on the user's LC_COLLATE setting, and the language-specific
collation order can even change over time.
Besides, the current collation order determination code has never worked
with the most common LC_COLLATE values like en_US.UTF-8.
Ideally, we would like to just order based on Unicode code points
to be reliably stable, but the existing implementation is case-insensitive,
so we are forced to rely on the unicode case mapping tables at least.
(This gives up on canonicalization and width-insensitivity, potentially
breaking users who rely on these previously documented properties.)

add the ability to create and run containers via the podman-remote
client.
we now create an intermediate layer from the the create/run cli flags.
the intermediate layer can be converted into a createconfig or into a
varlink struct. Once transported, the varlink struct can be converted
back to an intermediate layer and then to a createconfig.
remote terminals are not supported yet.

when pulling a non-existent image via varlink, we had a panic because
when we detected a pull error we sent the error over a channel but still
tried to deduce the image id on a nil object.

We were never using it. It's actually a potentially quite sizable
field (very expensive to decode an array of structs!). Removing
it should do no harm.

The flag should be substantially more durable, and no longer
relies on the create artifact.
This should allow it to properly handle our new named volume
implementation.
Signed-off-by: Matthew Heon <matthew.heon@pm.me>
Now that named volumes must be explicitly enumerated rather than
passed in with all other volumes, we need to split normal and
named volumes up before passing them into libpod. This PR does
this.

simplify the rootless implementation to use a single user namespace
for all the running containers.
This makes the rootless implementation behave more like root Podman,
where each container is created in the host environment.
There are multiple advantages to it: 1) much simpler implementation as
there is only one namespace to join. 2) we can join namespaces owned
by different containers. 3) commands like ps won't be limited to what
container they can access as previously we either had access to the
storage from a new namespace or access to /proc when running from the
host. 4) rootless varlink works. 5) there are only two ways to enter
in a namespace, either by creating a new one if no containers are
running or joining the existing one from any container.
Containers created by older Podman versions must be restarted.

in the few places where we care about skipping the storage
initialization, we can simply use the process effective UID, instead
of relying on a global boolean flag.
