  • Add logic for RUN_AND and RUN_OR
  • Add functions
  • Implement all types of redirections
  • Think of some strategy to implement control flows like while, case, and if, possibly in Make a tokenizer to replace filpinfo #4.

Implement all redirections.

One TODO done for #5.

However, filpinfo doesn't seem to be parsing correctly. #4 TODO,
but I'll probably write some work-arounds.

Also used more xcalloc instead of xmalloc+memset.
Two `*_init` functions removed.

A parser is pending, so nothing works here.
