libcgroup: Better error reporting for libcgroup
From: Ankita Garg <ankita@in.ibm.com>
This patch adds human readable error messages to the configuration parser.
The error lookup is implemented as a simple table, indexed by the error.
TODO: Save errno at ECGOTHER and pass it down as cgroup_lasterror.
