Here is the v2 of the patch which introduces APIs to read controller

specific stats. Added Makefile.am updates which I had missed in the
previous post.

New APIs to read controller specific statistics.

This patch introduces 3 new APIs which can be used to read controller
statistics iteratively. (Eg. stats from memory.stat etc)

Reading of stats is initiated by cgroup_read_stats_begin() API, which
returns the first stat of the requested controller in addition to returing
a handle that should be used in subsequent reads.

cgroup_read_stats_next() API can be used to read the remaining stats
one by one. This needs the handle returned by cgroup_read_stats_begin().

cgroup_read_stats_end() API will terminate the stats reading iteration
initiated by cgroup_read_stats_begin().

Changelog:

v2
- Update tests/Makefile.am so that it generates appropriate rules
  for tests/read_stats.c in the Makefile. This is in addition to
  the manual updates done to the generated file tests/Makefile.in.

v1
- cgroup_read_stats apis now work with relative cgroup path names instead
  of absolute path names.

v0
- Initial post.
