[PATCH v2 0/2] capabilities: Ambient capabilities

[Andy Lutomirski]

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.

Changes from v1:
 - Lots of cleanups to the ambient cap code.
 - The securebit is new.
