Sameer Rahmani 9be27c124a [Bootstrap] Use Serene itself to load and run the main function
This commit consist a series of fixes to make the reach the main
goal of the commit:

* Fix the 'MakeNodeFromExprs' behavior so it returns a pointer
  to a node and if the number of input exprs is zero then nil.

* Fix all the eval loop to return immediately in case of any error
  duh!

* Add a `errtype` field to `Error` with an `ErrType` enum type
  that indicates the type of the error, the type being syntax,
  semantic and runtime error at the moment.

* Rename some of the Error functions to match the error type. For
  Exapmle `MakeSyntaxError` and `MakeSemanticError`

Sameer Rahmani 0b56906474 [Bootstra] Rethink the eval loop to rewrite evaluation tree
Implement a new algorithm to eliminate TCO while preventing
premature execution exit by rewriting the evaluation tree and
replacing old nodes with new set of forms, for example the result of
some old form's evaluation, a body of a function or anything in
that nature. Couple the new forms with a possible new execution scope.

Sameer Rahmani 42058568c7 Add support for native function, multi ns require fn and 'builtins'
* Implemented Native function as IExprs so we can refer to them
  like any other function. Checkout `NativeFunction`.

* `require` has been implemented as a native functions which
  accepts one or more namespace descriptions and load them.
  A namespace description is either a symbol with the ns name
  or an `IColl` in the following form `(some.ns.name alias).

* A hashmap of strings to native functions has been added to the Runtime
  which is used to resolve builtin functions.
