Fixes

• A lot for ARM cross-compile
• Fsnotifies dumping didn't work on NFS
• Images auto-deduplication only worked one level up
• Packet socket ID was treated as file-descriptor and close()-d
• Badly counted pages stats on restore
• Linked remap name conflict when dump and restore on NFS
• Sporadic failures in memory draining due to huge pipes used
• Broken criu show of repeated fields
• Failure to open mountpoint in foreign pid namespace
• Unlinked bound unix socket dump error
• Small memory leak when writing to incremental image(s)
• Restoring fsnotify for links results in ELOOP
• Host's PATH is not suitable when execv-ing tar/ip/iptable to restore namespace (workaround, proper fix will be in 1.3)
• Using subdirs in log file name via RPC breaks security
