After seeing #7759, I decided to look at the calls in
Podman and Buildah to see if we had issues with strings.Split()
calls where an "=" (equals) sign was in play and we expected
to split on only the first one.
There were only one or two that I found in here that I think
might have been troubling, the remainder are just adding
some extra safety.
I also had another half dozen or so that were checking length
expectations appropriately, those I left alone.

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.

With the advent of Podman 2.0.0 we crossed the magical barrier of go
modules. While we were able to continue importing all packages inside
of the project, the project could not be vendored anymore from the
outside.
Move the go module to new major version and change all imports to
`github.com/containers/libpod/v2`. The renaming of the imports
was done via `gomove` [1].

Looks like a bit of a misunderstanding from early on.
Docker implements --filter=since=IMAGE. Podman implements 'after'
instead of 'since'. Add an equivalent case statement to handle
both, keeping 'after' because we have no way of knowing if it
is used in the field.
Update documentation ... and fix what looks like a complete
misinterpretation of what the code actually does: the man page
claimed that these were time fields, but I don't see any
possible incantation in which a time value works or could
work. Updated docs to reflect IMAGE usage. Also changed
nonworking '==' to single '='.
Added tests. [UPDATE: skip with broken podman-remote]

to make things more effecient for the api work we are doing, we should
process image filters internally (as opposed to in main). this allows
for better api responses and more closely affiliated functions.

to complete buildah transition.
