3a423f3e4e Change libcontainer to drop all capabilities by default. Only keeps
those that were specified in the config. This commit also explicitly
adds a set of capabilities that we were silently not dropping and were
assumed by the tests.

02b08b3961 Defend against infinite loop when following symlinks
ideally it should never reach it, but there was already multiple issues with infinite loop
at following symlinks. this fixes hanging unit tests

64b6d99e35 Adding test case for symlink causes infinit loop, reproduces: dotcloud#5370
normally symlinks are created as either
ln -s /path/existing /path/new-name
or
cd /path && ln -s ./existing new-name

but one can create it this way
cd /path && ln -s existing new-name

this drives FollowSymlinkInScope into infinite loop

4086e37e27 libcontainer: Ensure bind mount target files are inside rootfs
Before we create any files to bind-mount on, make sure they are
inside the container rootfs, handling for instance absolute symbolic

2d9fd36002 Always mount a /run tmpfs in the container
All modern distros set up /run to be a tmpfs, see for instance:
https://wiki.debian.org/ReleaseGoals/RunDirectory

Its a very useful place to store pid-files, sockets and other things
that only live at runtime and that should not be stored in the image.

This is also useful when running systemd inside a container, as it
will try to mount /run if not already mounted, which will fail for
non-privileged container.

ad35ca9f5b libcontainer: Create dirs/files as needed for bind mounts
If you specify a bind mount in a place that doesn't have a file yet we
create that (and parent directories). This is needed because otherwise
you can't use volumes like e.g. /dev/log, as that gets covered by the
/dev tmpfs mounts.

caca8eec08 beam/data: Message.GetOne() returns the last value set at a key
This is a convenience for callers which are only interested in one value
per key. Similar to how HTTP headers allow multiple keys per value, but
are often used to store and retrieve only one value.

c2a237f019 Fix stdin handling in engine.Sender and engine.Receiver
This introduces a superficial change to the Beam API:

* `beam.SendPipe` is renamed to the more accurate `beam.SendRPipe`
* `beam.SendWPipe` is introduced as a mirror to `SendRPipe`

There is no other change in the beam API.
