Examples:
- "foo$1" becomes "pkg.foo$1"
- "init$1" (meaning the first declared "init" function) becomes "init#1",
to distinguish it from "init$1" (meaning the first anonymous function
within the synthetic "init" function that initializes package-level vars).
It is now an invariant that all source-level (non-synthetic)
functions have distinct names, and that all names include the
enclosing package. Added test for this.
+ updated various clients.

Before, they were named func@line:col which made them easy to find in the source if you know the file, but hard if you don't, and it made tests fragile.
Now, they are named outer$1, outer$2, etc, which makes them
more informative in a UI since "outer" has meaning.
