getrusage

The syscall getrusage is used to get user program resource usage. It is a nice syscall. But only nice if kernel has all the nice bookkeeping. It is a luxury for us to have all the counting.

The syscall is added recently due to wait family syscalls, which use and bookkeep some of rusage.

As on the last updated date (Mar 7), the syscall in Lego only reports number of context switches and a few others.
