fix cgroup_get_value_string problem with *.stat output
the problem was in the low limit for value for the output of stat variables - now there are used the functions cgroup_read_stats_{begin/next/end} for this purpose
bogus output:
./src/tools/cgget -r memory.stat /
/:
memory.stat=cache 1024561152
rss 291270656
pgpgin 1209259
pgpgout 888011
inactive_anon 8192
active_anon 2976481
fixed output:
$ ./src/tools/cgget -r memory.stat /
/:
memory.stat=cache 1024610304
rss 291270656
pgpgin 1209271

v2:
removed bunch of unnecessary error messages
This patch adds to cgget option -a:
-a print the variables for all controllers which consists given cgroup
EXAMPLE:
$ ./cgget -a /daemons
/daemons:
cpuset.memory_spread_slab=0
cpuset.memory_spread_page=0
cpuset.memory_pressure=0
cpuset.memory_migrate=0
cpuset.sched_relax_domain_level=-1
cpuset.sched_load_balance=1
cpuset.mem_hardwall=0
cpuset.mem_exclusive=0
cpuset.cpu_exclusive=0
cpuset.mems=
cpuset.cpus=
cpuacct.stat=user 0
system 0
cpuacct.usage_percpu=0 0
cpuacct.usage=0

adds new option -g to cgget command
* the option has one argument - controller
* cgget -g devices / returns the values of all variables of controller
devices
* the option could be used multiple times
EXAMLES:
$ ./cgget -n -g cpu -r cpuset.mems /
cpu.rt_period_us=1000000
cpu.rt_runtime_us=950000
cpu.shares=1024
cpuset.mems=0

Add a tool to query for parameter values. The syntax is very similar to cgset,
including IMHO ugly group specification without list of controllers.
Usage:
cgget [-nv] -r <param. name> [-r <param. name>] [...] <path to group> [...]
-n - no headers
-v - print values only (no parameter names)
Example:
$ cgget -r cpuset.cpus / /second
/:
cpuset.cpus=0-1
/second:
cpuset.cpus=1
$ cgget -nv -r cpuset.cpus / /second
0-1
1
