Bug#1022003: transition: gssdp/gupnp 1.2->1.6 (+ rygel 0.42.0)

[Andreas Henriksson <andreas@fatal.se>]

Hello,

I've just started looking at building patched reverse dependencies and
ran into some issues.

librm has upstream commits that adds support for gssdp/gupnp 1.6, but
apparently hasn't actually ported to libsoup-3.0 yet so it completely
fails to build if using this... upstream issue filed and followed up on
the librm blocker bug.
This is probably the main blocker for this transition to proceed now,
unless you're willing to temporarily remove src:librm and its reverse
dependency roger-router from testing.

caja-extensions doesn't seem to use soup API's directly, but I can't
test-build since building is currently blocked by the ongoing perl
transition.

dleyna-{core,renderer,server} is now upstream maintained by the same
person maintaining gssdp/gupnp/rygel, so I presume this port actually
works .... but as mentioned I'd prefer to RM these rather than keep
carrying the orphanage.

Regards,
Andreas Henriksson
