This fixes all of the tests that were broken as part of the console
rewrite. This includes fixing the integration tests that used TTY
handling inside libcontainer, as well as the bats integration tests that
needed to be rewritten to use recvtty (as they rely on detached
containers that are running).
This patch is part of the console rewrite patchset.

This implements {createTTY, detach} and all of the combinations and
negations of the two that were previously implemented. There are some
valid questions about out-of-OCI-scope topics like !createTTY and how
things should be handled (why do we dup the current stdio to the
process, and how is that not a security issue). However, these will be
dealt with in a separate patchset.
In order to allow for late console setup, split setupRootfs into the
"preparation" section where all of the mounts are created and the
"finalize" section where we pivot_root and set things as ro. In between
the two we can set up all of the console mountpoints and symlinks we
need.
We use two-stage synchronisation to ensures that when the syscalls are
reordered in a suboptimal way, an out-of-place read() on the parentPipe
will not gobble the ancilliary information.

In user namespaces, we need to make sure we don't chown() the console to
unmapped users. This means we need to get both the UID and GID of the
root user in the container when changing the owner.

This updates runc and libcontainer to handle rlimits per process and set
them correctly for the container.

This commit adds support to libcontainer to allow caps, no new privs,
apparmor, and selinux process label to the process struct so that it can
be used together of override the base settings on the container config
per individual process.
