Tejun Heo 69d0206c79 cgroup: bring some sanity to naming around cg_cgroup_link
cgroups and css_sets are mapped M:N and this M:N mapping is
represented by struct cg_cgroup_link which forms linked lists on both
sides.  The naming around this mapping is already confusing and struct
cg_cgroup_link exacerbates the situation quite a bit.

>From cgroup side, it starts off ->css_sets and runs through
->cgrp_link_list.  From css_set side, it starts off ->cg_links and
runs through ->cg_link_list.  This is rather reversed as
cgrp_link_list is used to iterate css_sets and cg_link_list cgroups.
Also, this is the only place which is still using the confusing "cg"
for css_sets.  This patch cleans it up a bit.

* s/cgroup->css_sets/cgroup->cset_links/
  s/css_set->cg_links/css_set->cgrp_links/
  s/cgroup_iter->cg_link/cgroup_iter->cset_link/

* s/cg_cgroup_link/cgrp_cset_link/

* s/cgrp_cset_link->cg/cgrp_cset_link->cset/
  s/cgrp_cset_link->cgrp_link_list/cgrp_cset_link->cset_link/
  s/cgrp_cset_link->cg_link_list/cgrp_cset_link->cgrp_link/

* s/init_css_set_link/init_cgrp_cset_link/
  s/free_cg_links/free_cgrp_cset_links/
  s/allocate_cg_links/allocate_cgrp_cset_links/

* s/cgl[12]/link[12]/ in compare_css_sets()

* s/saved_link/tmp_link/ s/tmp/tmp_links/ and a couple similar
  adustments.

* Comment and whiteline adjustments.

After the changes, we have

	list_for_each_entry(link, &cont->cset_links, cset_link) {
		struct css_set *cset = link->cset;

instead of

	list_for_each_entry(link, &cont->css_sets, cgrp_link_list) {
		struct css_set *cset = link->cg;

This patch is purely cosmetic.

v2: Fix broken sentences in the patch description.
