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.

Revert: #935Fixes: #946
I can reproduce #946 on some machines, the problem is on
some machines, it could be very fast that modify time
of `memory.kmem.limit_in_bytes` could be the same as
before it's modified.
And now we'll call `SetKernelMemory` twice on container
creation which cause the second time failure.
Revert this before we find a better solution.

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.

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.

There's no point in changing directory here. Syscalls are resolved local
to the linkpath, not to the current directory that the process was in
when creating the symlink. Changing directories just confuses people who
are trying to debug things.

Comparisons with paths aren't really a good idea unless you're
guaranteed that the comparison will work will all paths that resolve to
the same lexical path as the compared path.

This removes the use of a signal handler and SIGCONT to signal the init
process to exec the users process.

Prior to this change a cgroup with a `:` character in it's path was not
parsed correctly (as occurs on some instances of systemd cgroups under
some versions of systemd, e.g. 225 with accounting).
This fixes that issue and adds a test.
