When the string is formatted including a constant transport name,
just call the transport to create or parse a reference explicitly.
This avoids unnecessary string formatting and parsing.
Then drop image.TarballTransport, which has no remaining users.

who must continue to use it (notably the varlink API - or is

We already have a c/image/docker/reference.Named; no need to
round-trip it through a string. This also eliminates the theoretical
parsing failure, and the unchecked .(reference.Named) cast.
Also add a check for DockerReference() == nil to be extra paranoid,
although that should never happen.

(... but keep it in DefaultTransport, which remains irregular.)
This makes DockerTransport consistent with the others, and much more importantly,
allows several instances to do
> imgRef.Transport().Name() == DockerTransport
instead of the current
> strings.HasPrefix(DockerTransport, imgRef.Transport().Name())
, which currently works but is pretty nonsensical (it does not check
the "docker://" prefix against the _full reference_, but it checks
the _transport name_ as a prefix of "docker://", i.e. a transport named
"d" would be accepted.
Should not change behavior, because the only currently existing transport
which has a name that is a prefix of "docker://" is c/image/docker.Transport
(but does not add unit tests).

Because srcRef is created by parsing imgName, both hard-code assumptions
about transport-specific formats of the strings, so that is neither better nor worse;
but we do less explicit parsing.
Should not change behavior for dir:, nor for fully-correct docker-archive:.
docker-archive:, though, also supports docker-archive:path:reference, where
the reference is ignored (with a warning) on read; in such cases the previous
code would use the reference only (not the path), the new code uses both
as the path. Neither works, we just change the failure mode (but
"error opening path:reference" is now more suggestive of the correct usage).

This is the stage 1 effort for an image library that can be eventually used by buildah and
podman alike. In eventuality, the main goal of the library (package) is to:
* provide a consistent approach to resolving image names in various forms (from users).
* based on the result of the above, provide image methods that in a singular spot but separate from the runtime.
* reduce the cruft and bloat in the current podman runtime.
The goal of stage 1 is to demonstrate fast, accurate image resolution for both local and remote images resulting in
an image object as part of the return.
