Fixes

• R/O-mounted root could block the dump

• Cgroup fs bind mounts were detected with error
• Unaligned futex-es in parasite could cause dump to crash
• When compiled with gcc-4.9 parasite code crashed
• Failure to freeze cgroup didn't result in aborting of dump
• Wrong ns list was parsed when dumping userns (invisible since nesting works only for mntns)
• Non-inheritable non-tty as stdin caused shell-job restore to erroneously fail
• Error path in criu dedup could crash

Deprecated

• Per-pid rlimit, itimers and posix-timers
• Separate image for epoll tfds (target file descriptors)
