We can certainly drop all the 4.x versions. The host OS those are
officially supported on are very outdated:

Although the catch all "All distributions" suggest it might work with
newer distros, they are clearly a second tier from a support POV. All
these explicitly targetted distros are outside libvirt's support policy.
There is a question as to whether to delete 5.0 and 5.1 support from
libvirt.
There are no remainining #ifdef VBOX_API_VERSION conditionals in the
vbox_tmpl.h file related to code differences between 5.0, 5.1 and 5.2,
so keeping them is not a maint burden in code.
The main burden is distributing the large vbox_CAPI_v5_0.h and
vbox_CAPI_v5_1.h files which are ~1 MB in size (uncompressed)
or ~85 kb (xz compressed). IOW versions 5.0 and 5.1 increase
the release tarballs by a small amount, but nothing that is
too unreasonable vs the overall size of 14 MB for libvirt source.
Thus I have kept 5.0 and 5.1 support.
VirtualBox 6.0 came out in Dec 2018 and given past practice it
would not suprise me if that has API changes impacting libvirt.
So some interested party might want to look at supporting that
in libvirt.
In v2:
- Also remove deleted files from the Makefile
- Stop including the old deleted 4.0 API file
