unfortunately rootless won't work without cgo, as most of the
implementation is in C, but at least allow to build libpod.

some podman commands do not require the use of a container/image store.
in those cases, it is more effecient to not open the store, because that
results in having to also close the store which can be costly when the
system is under heavy write I/O loads.

Podman 1.4.1 had problems with builds with a
RUN command that tried to to a privliged command.
This adds a gating test for that situation.

Currently pause process blocks all signals which may cause its
termination, including SIGTERM. This behavior hangs init(1) during
system shutdown, until pause process gets SIGKILLed after some grace
period. To avoid this hanging, SIGTERM is excluded from list of blocked
signals.

at least on Fedora 30 it creates the /run/user/UID directory for the
user logged in via ssh.
This needs to be done very early so that every other check when we
create the default configuration file will point to the correct
location.

Turn of go modules to avoid breaking build environments to accidentally
try pulling the dependencies instead of using the ./vendor directory.

we had a regression where the rootless user tried to use the global
configuration file. We should not try to use the global configuration
when running in rootless but only cherry-pick some settings from there
when creating the file for the first time.

This is an initial implementation of cgroup v2 support for
pkg/cgroups. It currently works with crun, with this patch:
https://github.com/giuseppe/crun/pull/49).
It adds the pieces for:
- set PID limit to 1
- retrieve stats so that "podman stats" work.
the only missing part is the support for reading per
CPU stats (that is cpuacct.usage_percpu on cgroup v1), so for now it
always returns an empty result.

provide a package for managing cgroups. This is not supposed to be a
complete implementation with all the features supported by cgroups,
but it is a minimal implementation designed around what libpod needs
and it is currently using.
For example, it is currently possible to Apply only the pids limit,
as it is used by libpod for stopping containers, any other Apply will
just fail.
The main goal here is to have a minimal library where we have full
control, so we can start playing with cgroup v2.
When the need arises, we can add more features.

When a container is attached upon start, the WaitGroup counter may
never be decremented if an error is raised before start, causing
the caller to hang.
Synchronize with the start & attach goroutine using a channel, to be
able to detect failures before start.
