* Remove the duplicate vlc.rdef that was embedded in the patchset
for vlc-0.8.6i and, instead, make it use the same vlc.rdef that
vlc-2.2.1 already uses and which is in additional-files.
* Tweak vlc.rdef to make it usable with any version of vlc.
* Add TEST() with "make check" (to both 0.8.6i and 2.2.1).
* Fix the recipe of VLC 2.2.1 to make it build on x86 2nd arch.
* Force VLC 2.2.1 to use lib:libswscale from ffmpeg2. BTW,
it seems this version of VLC cannot compile against ffmpeg >= 3.
* Comment out the lib:libdevice in REQUIRES because the haiku hpkg is
missing a PROVIDES for it.
* VLC 0.8.6i was previously using libdvbpsi 1.2.0 but the compilation
now fails for some reason (unknown to me). The compilation also
fails when building against libdvbpsi 1.3.0, so drop support for it
in VLC 0.8.6i. VLC 2.2.1 on x86 secondary arch builds fine with any
of the mentioned releases of libdvbpsi, though.
