In some older kernels setting swappiness fails. This happens even
when nobody tries to configure swappiness from docker UI because
we would still get some default value from host config.
With this we treat -1 value as default value (set implicitly) and skip
the enforcement of swappiness.
However from the docker UI setting an invalid value anything other than
0-100 including -1 should fail. This patch enables that fix in docker UI.
without this fix container creation with invalid value succeeds with a
default value (60) which in incorrect.

The creation of the profile should be handled outside of libcontainer so
that it can be customized and packaged.

Update the tests to use the test-friendly GetAdditionalGroups API,
rather than making random files for no good reason.

The old GetAdditionalGroups* API didn't match the rest of
libcontainer/user, we make functions that take io.Readers and then make
wrappers around them. Otherwise we have to do dodgy stuff when testing
our code.

This moves much of the documentation on contributing and maintainer the
codebase from the libcontainer sub directory to the root of the repo.

A directory with a hyphen currently generates an InvalidId error because
of the regex in libcontainer. I don't believe there is any reason a
hyphen should be disallowed.

It can happen if newContainer is failed. Now test shows real error from
newContainer instead of trace.
