These ebuilds are a bit hard to read (they are complex beasts) but it
appears that you don't need libgudev anymore. Perhaps it's now part of
systemd itself and it's presence requires a systemd that can work with
it as you have it?

I recommend you unmerge libgudev and try again, let portage figure out
what to do. Make a note of your USE for libgudev so you can put it back
if needed

This stuff is just info, portage justifying it's behaviour to you
(portage is very verbose at the times you don't want it to be...)

It's not upgrading x264 to atest available, everything below is the
reason why:

This is the latest version in the tree

vlc needs subslot 0/142 because it's ebuild says so. This can be
satisfied, but it's not the latest x264 in the tree, and portage is
telling you why

same general idea as x264

and this is more explanatory data about why you need systemd, sysvinit
and libgudev. Normally it's a good idea to print why blockers are being
pulled in, but in this case systemd is a basic package and gets pulled
in by many things. It makes for a long and confusing list
