[CRIU] [RFC 0/2] cgroups: Support dynamic controller properties

[Cyrill Gorcunov]

While been working on another project I found that for custom kernels
we don't provide an ability to c/r non-standart cgroup properties.

Here we implement dynamic support of cgroup properties: one can
pass --cgroup-props option where all entries needed are described
in json format and CRIU will dump them.

Note for parsing json we use Jansson library but it's compilation
dependant: if there is no such library found on the system the feature
get simply not supported.

Cyrill Gorcunov (2):
  cgroup: properties -- Move properties handling into separate file
  cgroup: Add ability to dump custom cgroup properties
