- Update VirtualBox OSE to 6.1.18
- Old VirtualBox OSE 5.2.44 preserved as "-legacy" versions of the
  ports (repocopied)
- Add back extra patch removed in r528258, actually required to
  build DEBUG kmod
- Correctly define WITH_DEBUG when enabling the DEBUG option, so
  binaries are not stripped

Please note that this new version supports only amd64 CPUs. If you need
to use older hardware please install the legacy ports.

Note that moving VM snapshots across major updates is unsupported, it's
strongly suggested to properly shutdown VMs before upgrading, please
check UPDATING for further details.

This update is the result of work from many people, and thanks to all
who gave feedback and tested things.

Patch based on work from: Mario Lobo <lobo@bsd.com.br> and jkim.

emulators/virtualbox-ose: Switch build to USES= compiler:c++14-lang

The runtime breakage that started occurring after the LLVM 7 -> 8 transition
has been diagnosed with help from cem@, and the attached patch fixes it. The
problem ended up being that tail-call optimization was being applied to this
function (which should probably be written in assembly instead) and moving
the tail-call to later on after some stack manipulations. The problem with
this is that this particular function uses alloca() to carefully craft a
stack that it's expecting to be used for the function it's calling at the
end.

The new patch fixes this using a technique that was committed later on in
upstream changeset 75061 to address a similar failure with GCC sanitizers
enabled. The FreeBSD-specific component of this patch is using the different
stack setup if __clang__ is defined as well.
