Optimizations

Fixes
- Bad checks for kcmp() ret codes resulted in errors in file sharing detection
- Multiple mmap-s of same files with different flags blocked the restore
- Integer overflow in huge mapping restore caused restoration failure
- Devpts's newinstance option was lost during dump
- Subsequent dump could try to find old mem dump for newly forked task
- Bad detection of overmounted mountpoints on fsnotify restore
- Page-server could read partial message and failed
- Errors in dumping of two subsequent anon vmas in some cases
- Irmap mis-compared devices for disk FS-s
- TMPFS handles always change during dump/restore
- Pre-dump sometimes hangs on FIFO-s
- Post-restore script fails too late (if does it)
