add a new option --preserve-fd that allows to specify a list of FDs to
pass down to the container.
It is similar to --preserve-fds but it allows to specify a list of FDs
instead of the maximum FD number to preserve.
--preserve-fd and --preserve-fds are mutually exclusive.
It requires crun since runc would complain if any fd below
--preserve-fds is not preserved.

Pass the _entire_ environment to conmon instead of selectively enabling
only specific variables. The main reasoning is to make sure that conmon
and the podman-cleanup callback process operate in the exact same
environment than the initial podman process. Some configuration files
may be passed via environment variables. Podman not passing those down
to conmon has led to subtle and hard to debug issues in the past, so
passing all down will avoid such kinds of issues in the future.

The attach API used to always return the Content-Type
`vnd.docker.raw-stream`, however docker api v1.42 added the
`vnd.docker.multiplexed-stream` type when no tty was used.
Follow suit and return the same header for docker api v1.42 and libpod
v4.7.0. This technically allows clients to make a small optimization as
they no longer need to inspect the container to see if they get a raw or
multiplexed stream.

Package `io/ioutil` was deprecated in golang 1.16, preventing podman from
building under Fedora 37. Fortunately, functionality identical
replacements are provided by the packages `io` and `os`. Replace all
usage of all `io/ioutil` symbols with appropriate substitutions
according to the golang docs.

Podman adds an Error: to every error message. So starting an error
message with "error" ends up being reported to the user as
Error: error ...
This patch removes the stutter.
Also ioutil.ReadFile errors report the Path, so wrapping the err message
with the path causes a stutter.

On FreeBSD, ENOTCONN can be reported if shutdown is called on a unix
domain socket where the remote end is already closed. This change
ignores those errors instead of printing an error message on container
exit.

This moves the code which sets the process capabilites for the exec to
oci_conmon_exec_linux.go since this is a linux-specific feature. Adding
a no-op stub for FreeBSD enables 'podman exec' when using the ocijail
runtime.
