* kcomd completion
* migrating current API to kcomd
* handle execve_on_remote correctly.
* simplify fork_on_remote thanks to kcomd.
* fix process coming back when there's a problem (unsupported syscall,
  etc...) on the remote
* completion of process, doesn't return back the exit value to deputy.
- fix some _user macro that are not supposed to sleep to work with kcomd
  (workaround already there AFAIK)
- move /proc use to /omctrfs/
- known nodes export through /omctrlfs
- move nodes structure to reference count.
- handle 32 bit migrated process on 64 bit
- fix remote to remote. will be easier with kcomd.

'*' are mandatory

access to remote cpus information, are to be done through userspace.
specially since the kernelspace has no idea on the real map of nodes.
kernel has a narrow view of the map, which consist on only the nodes
it is communicating with (processes migrated to or from this node)
