cleanup code indent
Cleanup the code indent using:
find . -name *.c -exec Lindent {} \;
It's really a big change, but can fix almost all of
the indent problem in C code, although we can't
ensure all of the changes are right, but the error
changes are really few.

Add Freezer Controller Testcases: These testcases cover the basic functionality of the kernel cgroup freezer controller described in the kernel's Documentation/cgroups/freezer-subsystem.txt file. Briefly:
The freezer subsystem in the cgroup filesystem defines a file named freezer.state. Writing "FROZEN" to the state file will freeze all tasks in the cgroup or return with errno EBUSY if the group can't be frozen immediately (use /bin/echo if you wish to check exit codes). After a successful write of "FROZEN" writing "THAWED" will unfreeze the tasks in the cgroup. Reading will return the current state. Note that freezer.state doesn't exist in the root cgroup, which means the root cgroup is non-freezable.
* Sample usage:
$ mkdir /containers
$ mount -t cgroup -ofreezer freezer /containers
$ mkdir /containers/0
$ echo $some_pid > /containers/0/tasks
$ cat /containers/0/tasks/freezer.state
THAWED
$ echo FROZEN > /containers/0/tasks/freezer.state
<IO Error (busy)>
$ cat /containers/0/tasks/freezer.state
FREEZING
$ sleep 0.2
$ echo FROZEN > /containers/0/tasks/freezer.state
$ cat /containers/0/tasks/freezer.state
FROZEN
$ echo FROZEN > /containers/0/tasks/freezer.state
$ cat /containers/0/tasks/freezer.state
THAWED
The bulk of the code is in libcgroup_freezer. Early tests cover the initialization used for the bulk of the tests. Each testcase is a brief shell script composed of your typical three phases:
Initialization
sourcing libcgroup_freezer
mounting the cgroup filesystem
making a sample cgroup
making a sample process [optional]
Test body
Actions:
freeze, thaw, move to (new) cgroups
try to fork new processes
signal sequences
Assertions interleaved with the actions:
cgroup/task existence
cgroup/task state
cgroup membership
Cleanup
The patch runs these tests when the other cgroup controller tests run but is otherwise independent of the infrastructure offered by those controller tests. Also, these tests may be carefully run by hand or via the run.sh script provided. Signed-off-by: Matt Helsley <matthltc@us.ibm.com>.
