Alexander Morozov 7679c80be5 libcontainer/configs: make hooks run safer
It's possible that `cmd.Process` is still nil when we reach timeout.
Start creates `Process` field synchronously, and there is no way to such
race.

configs: fix json tags for CpuRt* options
Previously we used the same JSON tag name for the regular and realtime
versions of the CpuRt* fields, which causes issues when you want to use
two different values for the fields.

Hushan Jia bb42f80a86 fix setting net_cls classid
Setting classid of net_cls cgroup failed:

ERRO[0000] process_linux.go:291: setting cgroup config for ready process caused "failed to write 𐀁 to net_cls.classid: write /sys/fs/cgroup/net_cls,net_prio/user.slice/abc/net_cls.classid: invalid argument"
process_linux.go:291: setting cgroup config for ready process caused "failed to write 𐀁 to net_cls.classid: write /sys/fs/cgroup/net_cls,net_prio/user.slice/abc/net_cls.classid: invalid argument"

The spec has classid as a *uint32, the libcontainer configs should match the type.

Phil Estes 0b5581fd28 Handle memory swappiness as a pointer to handle default/unset case
This prior fix to set "-1" explicitly was lost, and it is simpler to use
the same pointer type from the OCI spec to handle nil pointer == -1 ==
unset case.

Also, as a nearly humorous aside, there was a test for MemorySwappiness
that was actually setting Memory, and it was passing because of this
bug (as it was always setting everyone's MemorySwappiness to zero!)

Aleksa Sarai db3159c9d9 libcontainer: cgroups: add pids controller support
Add support for the pids cgroup controller to libcontainer, a recent
feature that is available in Linux 4.3+.

Unfortunately, due to the init process being written in Go, it can spawn
an an unknown number of threads due to blocked syscalls. This results in
the init process being unable to run properly, and thus small pids.max
configs won't work properly.
