There were many situations that made exec act funky with input. pipes didn't work as expected, as well as sending input before the shell opened.
Thinking about it, it seemed as though the issues were because of how os.Stdin buffers (it doesn't). Dropping this input had some weird consequences.
Instead, read from os.Stdin as bufio.Reader, allowing the input to buffer before passing it to the container.

when running a container remotely, we should only be sending stdin when
running with --interactive; otherwise use nil.

This change matches what is happening on the podman local side
and should eliminate a race condition.
Also exit commands on the server side should start to return to client.

the compilation demands of having libpod in main is a burden for the
remote client compilations. to combat this, we should move the use of
libpod structs, vars, constants, and functions into the adapter code
where it will only be compiled by the local client.
this should result in cleaner code organization and smaller binaries. it
should also help if we ever need to compile the remote client on
non-Linux operating systems natively (not cross-compiled).

Although an upgraded call is requested, the server has to send at least
one reply (can be an error) and the client has to check the reply,
before assuming an upgraded connection.

Ensure when using remote attach --no-stdin a mock device is used to
prevent stdin and not nil. This fixes issue #3009.
When starting a container with the remote client, if the container is
already running and the user asks to attach, we should just attach.
This fixes issue #3011

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.
