prebirth: Globally unique functions
This was implicit in the `define-block' implementation because of the
conversion from `<foo>' to `$foo$', but that's no longer the case.

This is just a simple, temporary implementation, so don't be alarmed.

* build-aux/bootstrap/libprebirth.js: Updated header documentation to
    mention `$$' prefix.
  ($$js$console): Renamed from `js$console'.
* build-aux/bootstrap/prebirth.js
  (_idFromName): Add `global' parameter to add `$$' prefix to generated
    identifiers.
  (_cdfn, _sexpToEs): Use it.

prebirth: Abandon `define-block' in favor of `define'
Turns out, I'll kill myself before writing a Prebirth compiler in a
block-define-based Prebirth Lisp.  So, let's degrade even further into a
primitive Scheme.  This is going down a dangerous path to simply
implementing Scheme...

Nonetheless, here I remove `define-block' in favor of a simple shorthand
function definition `define', as is custom in Scheme.  We will worry
about block definitions later as metadata mapping to normal functions.

Add prebirth.js
This is hopefully the beginning of a good thing that I'll actually
finish.  I began planning this project formally just before the beginning of
Aug 2017.

* build-aux/bootstrap/prebirth.js: New file.
