distrosort: add new distrosort.Names helper
This commit adds a new distrosort.Names() helper that can be
used sort sort distro names. It will take version numbers of
the distro into account and sort by semantic version. This
is useful in e.g. user-interfaces where we want to present
the version in a nicely sorted way.
Sorting follows the go-version library which supports semantic
versioning [0] so anything supported there will be sorted
correctly including -beta suffixes and similar (see the
spec for details).
Note that this is an extra pkg because the distro and distroid
would be circular imports otherwise. The alternative might be to
create a distro.ID package.
This commit adds a new method ID.Version() that returns a
go-version.Version object so that we can easily sort the distro
versions.
The ID.Version() currently also has to return an error because
the ID struct exposes MajorVersion/MinorVersion which means that
during the lifetime the Version may become invalid even after
ParseID was run. We could fix this by making {Major,Minor}Version
getters instead of the current way. Then we could also use the
version.NewVersion() library directy to parse the version string
from the ID and support things like -beta or other extras that
semantic versioning allows. But then that may interfere with the
distroid.Parser interface so definitely needs some more thinking.
