Multiple mount point support. Patches built on top of Dhaval'a patches.

Multiple mount point support. Patches built on top of Dhaval'a patches.
Works for me on my testing. NOTE: The testing is insufficient as we
only test cg_control_create_cgroup() and not delete_cgroup() or
attach_task(). Sudhir's new test cases should really help

Several coding style fixes and changes, enhancements to make the code
work.

NOTE: Since this is development release -DDEBUG is back in the makefile.
Once this is committed, I'll bump up the version to 0.05 if no one objects.
