namespaces: Add a namespace structure that represents a file

We have been always parsing a single function. Since we want to have
multiple functions in a near future, this patch introduces an namespace
that represents an entire file.

To ensure a function is defined inside a namespace, a helper function
was created. Today our ast_node structure is highly exposed, and this is
something that Johnny and I have been discussed. So then, this is a
first step to try to protected the code generation from our ast tree.
