Review request for mesos.


Changes
-------

I've address the comments and updated the diff. PTAL.


Summary
-------

The first of several patches related to resource usage monitoring. This patch provides a collection
of utilities for use on Linux for reading stats from proc. It is used by both the lxc and
proc resource collectors.


This addresses bug MESOS-89.

Sanity tests have been written in src/tests/proc_utils_tests.cpp for all utility functions,
and functions have been tested ad hoc.

> This is a utility for MESOS-38 https://issues.apache.org/jira/browse/MESOS-38
> Create a collection of utilities to read information from the proc filesystem. This will
be used in MESOS-38 to collect most of the information for the process-based isolation usage
reporting mechanism. These utilities will also be used for certain functionality in monitoring
lxc-based isolation because not all of the information needed is available via the cgroup
interface, such as the start time of the container.
