Revert "Pseudo terminals: add utility module"

It was noticed that the Python standard library provides os.ttyname(),
and, while it only returns the Pseudo Terminal file path when given
the slave file descriptor, it looks to be sufficient for most, if not
all, use cases.

This reverts commit 003bfaed.

Pseudo terminals: add utility module

On local runs, for non-root users, it's possible to verify
the contents of /proc/1/cmdline. Of course, we should do
this only if we are on a local run (process.run is passed
to get_name_of_init) and we couldn't directly read from
/proc/1/exe.

After this patch, it's possible to instantiate ServiceManager
on local runs made by non-root users.

Early state docs and tweaks

Based on previous experiences (GDB terminal redirection attempts),
it's common for applications that need to allocate a pseudo to have
the name of the allocated file. This is, unfortunately, something that
the Python standard library doesn't give for free.

This simple utility module wraps and extends the Python standard
library `pty` module, providing a `openpty` function that, besides
allocating the pseudo terminal, also returns its name.

These signal handlers are only used later in the code, and in a hope
to dimish the possible things that can go wrong before the initial
test state (AKA early state) is sent to the test runner, let's move
their definitions to a later stage.

Commit 63077e79 introduced the `make requirements` target. Let's use
that on the documentation, since it can cover more scenarios such
as Python 2.6 users.

There has been a lot of file location updates with the plugin architecture
changes.

Also python-stevedore is also required at build time, because on some
arches the selftests are run during the package build.

Let's reflect those in the RPM packages.

Plugins Overhaul [v1]

Signed-off-by: NCleber Rosa <crosa@redhat.com>

Optionally, users may have plugins that fail to load, but that should
still be kept installed. It can be annoying to have the same message
over and over, so let's allow users to configure which plugins should
have their load errors silenced.

Let's log when plugins fail to loaded for any reason. The error
message is given right after the plugins are attempted to be loaded,
so they may show before any other user visible output.

Yes, too many plugin mentions, in this commit title, but that's what
it really is, so please bear with it.

Now that the plugin types have a finer granularity, let's show each
plugin type (based on the namespace) as a separate section.
