The new{g,u}idmap binaries where a source of trouble for users when they lacked
sufficient privileges. This commit adds code to check for sufficient privilege.
It checks whether new{g,u}idmap is root owned and has the setuid bit set and if
it doesn't it checks whether new{g,u}idmap is root owned and has CAP_SETUID in
its CAP_PERMITTED and CAP_EFFECTIVE set.

Closes #296.

Add two new helpers that allow to determine whether a given proc or file has a
capability in the given set and move lxc_cap_is_set() to static function that
both call internally.

Resource Limits

These functions define pointer to their key shifted by a
number and guard access to it later via another variable.
Let's make this more explicit (and additionally have the
pointer be NULL in the case where it is not supposed to be
used).

This adds lxc.limit.<name> options consisting of one or two
colon separated numerical values (soft and optional hard
limit). If only one number is specified it'll be used for
both soft and hard limit. Additionally the word 'unlimited'
can be used instead of numbers.

Eg.
  lxc.limit.nofile = 30000:32768
  lxc.limit.stack = unlimited

Increased buffer length in print_stats()

Avoid waiting for bridge interface on bootup

Some "/sys" entries exceeds buffer size.
This results to some statistics loss ('BlkIO' in particular):

 wc -c /sys/fs/cgroup/blkio/lxc/alt/blkio.throttle.io_service_bytes
 318 /sys/fs/cgroup/blkio/lxc/alt/blkio.throttle.io_service_bytes
