This patch adds cgset tool, which sets parameters of controllers
for given cgroup based on input name-variable pairs
- the syntax is:
cgset -r <name=value> <relative path to cgroup>
-------------------------------------------------
EXAMPLES:
$ cgcreate -g cpuset:test1
$ cgset -r cpuset.cpus=1 test
$ cat ./test/cpuset.cpus
1
$ cgcreate -g cpuset:test1 -g cpuset:test2
$ cgset -r cpuset.cpus=0 test1 test2
$ cat /mnt/cgroups/cpuset/test1/cpuset.cpus
0
$ cat /mnt/cgroups/cpuset/test2/cpuset.cpus
0

CHANGELOG of v2.1:
================
* Rebase the patch for commit '340feae163c4797a6cb1247b3812c1ccdc52fa41'.
There are some similar functions for getting process's data (uid, gid) from
/proc/<pid>/status file, so this patch integrates these functions into one
cgroup_get_uid_gid_from_procfs().

This patch adds cgcreate tool, which creates cgroups based on input
parameters - the syntax is:
cgcreate -t <tuid>:<tgid> -a <agid>:<auid> -g <list of
controllers>:<relative path to cgroup>
where:
-a enables user to define admin gid and uid (implicit values are the
same values which are in the parent directory)
-t enables user to define task gid and uid (implicit values are the
same values which are in parent directory)
-g sets pairs list of controllers-relative path to cgroup
-------------------------------------------------
EXAMPLES:
* ../../libtool --mode=execute ./cgcreate -a :varekova -g cpuacct:first
* ll /mnt/cgroups/cpuacct | grep first
drwxrwxr-x 2 root varekova 0 2009-06-03 09:14 first

By default, everything is compiled. I want to add options to ./configure,
which can selectively disable tools, daemon and pam module. The library
itself is mandatory component and cannot be disabled.
Usage:
./configure --help
./configure --disable-tools --disable-pam --disable-daemon

I reviewed the libcgroup code in the viewpoint of memory-leak and
found some lacks of fclose(). This patch adds some fclose() calls
for error handling.

cgconfigparser can be executed only by root, so it should be installed to

Add automake makefiles and prepare everything to run, but don't actually
run the automake - it would generate lot of noise, where my manual changes
would get lots.
