Ensure pod REST API endpoints include ctr errors

The APIv2 pod endpoints that operate on multiple containers, such
as Start, Kill, Pause, Unpause, do not report errors encountered
by individual containers, because they incorrectly assume that
any error is fatal. The documentation for the Libpod API calls
notes, however, that ErrPodPartialFail will *always* be returned
if any container failed; so we need to ignore that error and
continue to collating and returning container errors.

Send HTTP Hijack headers after successful attach

Our previous flow was to perform a hijack before passing a
connection into Libpod, and then Libpod would attach to the
container's attach socket and begin forwarding traffic.
A problem emerges: we write the attach header as soon as the
attach complete. As soon as we write the header, the client
assumes that all is ready, and sends a Start request. This Start
may be processed *before* we successfully finish attaching,
causing us to lose output.
The solution is to handle hijacking inside Libpod. Unfortunately,
this requires a downright extensive refactor of the Attach and
HTTP Exec StartAndAttach code. I think the result is an
improvement in some places (a lot more errors will be handled
with a proper HTTP error code, before the hijack occurs) but
other parts, like the relocation of printing container logs, are
just *bad*. Still, we need this fixed now to get CI back into
good shape...

Commit 2b6dd3fb4384 set the killmode of the podman.service to the
systemd default which ultimately lead to the problem that systemd
will kill *all* processes inside the unit's cgroup and hence kill
all containers whenever the service is stopped.
Fix it by setting the type to sdnotify and the killmode to process.
`podman system service` will send the necessary notify messages
when the NOTIFY_SOCKET is set and unset it right after to prevent
the backend and container runtimes from jumping in between and send
messages as well.

The ListContainers API previously had a Pod parameter, which
determined if pod name was returned (but, notably, not Pod ID,
which was returned unconditionally). This was fairly confusing,
so we decided to deprecate/remove the parameter and return it
unconditionally.
To do this without serious performance implications, we need to
avoid expensive JSON decodes of pod configuration in the DB. The
way our Bolt tables are structured, retrieving name given ID is
actually quite cheap, but we did not expose this via the Libpod
API. Add a new GetName API to do this.

images: speed up lists

Listing images has shown increasing performance penalties with an
increasing number of images. Unless `--all` is specified, Podman
will filter intermediate images. Determining intermediate images
has been done by finding (and comparing!) parent images which is
expensive. We had to query the storage many times which turned it
into a bottleneck.
Instead, create a layer tree and assign one or more images to nodes that
match the images' top layer. Determining the children of an image is
now exponentially faster as we already know the child images from the
layer graph and the images using the same top layer, which may also be
considered child images based on their history.
On my system with 510 images, a rootful image list drops from 6 secs
down to 0.3 secs.
Also use the tree to compute parent nodes, and to filter intermediate
images for pruning.

This change ensures that we pull volume bind specification strings from
the correct spot in the POSTed data when creating containers. We should
probably canity check that the mapping keys in `Volumes` are a superset
of the binds listed in `HostConfig.Binds` but this cheap change removes
an annoying behaviour where named volumes or host mount would be
silently replaced with newly created anonymous volumes.

The versions Docker that the compat endpoints currently support are
using another type for the `filters` parameter than later versions
of Docker, which the libpod/events endpoint is also using.
To prevent existing deplopyments from breaking while still achieving
backward compat, we now support both types for the filters parameter.
Tested manually.

Fix a potential panic in the events endpoint when parsing the filters
parameter. Values of the filters map might be empty, so we need to
account for that instead of uncondtitionally accessing the first item.
Also apply a similar for race conditions as done in commit f4a2d25c0fca:
Fix a race that could cause read errors to be masked. Masking
such errors is likely to report red herrings since users don't
see that reading failed for some reasons but that a given event
could not be found.
Another race was the handler closing event channel, which could lead to
two kinds of panics: double close, send to close channel. The backend
takes care of that. However, make sure that the backend stops working
in case the context has been cancelled.

StateHijacked is a terminal state. If hijacked connection
is registered as an active connection, connection will
never be unregistered. This causes two issues
First issue is that active connection counters are off.
Second issue is a resource leak caused by connection
object that is stored to a map.
After this patch hijacked connections are no longer
visible in counters. If a counter for hijacked
connections is required, podman must track
connections returned by Hijacker.Hijack()
It might make sense to develop abstraction layer for
hijacking - and move all hijacking related code to a
separate package. Hijacking code is prone to resource
leaks and it should be thoroughly tested.
