This adds ambient capabilities. See the individual patch changelogs
for details.
Preliminary userspace code is here:
https://git.kernel.org/cgit/linux/kernel/git/luto/util-linux-playground.git/commit/?h=cap_ambient&id=7f5afbd175d2
I'll follow up with a rough draft of a man-pages patch.
Just as a note: I'm going to hold off on v3 until Kees and/or Serge
can take a look, since so far the only changes I want to make to the
kernel part are some comment cleanups and a possible rearrangement of
the pE' stuff that will provably have no effect.
