Kernel: Add /proc/{pid}/children to ProcFS

Browse source 
This exposes the child processes for a process as a directory
of symlinks to the respective /proc entries for each child.

This makes for an easier and possibly more efficient way
to find and count a process's children. Previously the only
method was to parse the entire /proc/all JSON file.
