[Crash-utility] [PATCH] Add a new option -r to cgget

[Zhang Xiaohe]

Hello Dave,

This patch allows cgget to display one or some parameters of a
controller of cgroup and fix some bugs.
One will find it more efficient when he just focus on some
parameters instead of the whole controller.

Here are examples:
1.
crash> cgget -r cpuset.mems /
/:
cpuset.mems: 0

2.
crash> cgget -r memory.usage /
/:
memory.memsw.max_usage_in_bytes: 0
memory.memsw.usage_in_bytes: 1368694784
memory.max_usage_in_bytes: 0
memory.usage_in_bytes: 1368694784

To apply this patch, enter to crash-<version> directory and run
the commands as follows:
$ cp cgget.pacth ./
$ patch -p0 -i cgget.patch

For more information, please refer to the attachment.

Thanks.
