map, and chan. First step in Russ' proposal.

- removed explicit "export" declarations and keyword
- fixed a few glitches and adjusted examples
(The details of what "export" mean should be clarified
in the spec, this is just so we have a working doc for
now.)

Instead of trying to make open arrays look like arrays (which they aren't,
they just look like them), I decided to call them "slice types". As a result
they have value semantics, and one can really talk about what they really are.
Note:
- There are lots of missing details
- There are probably lots of mistakes
Looking for some initial feedback.

- simpler, clearer, and shorter overall
- no spec changes

Also: Removed uses of "we" and replaced by impersonal language.
Minor cosmetic changes.

I have deliberately removed the wording about receivers where it was
before because I think it needs to be more precise. There is a TODO.

(for instance *p was not allowed on the left side of "="). Changed
to Expression everywhere (this is too liberal, UnaryExpr is probably
good enough, but it seems funny, and we need to check semantically
anyway). This matches 6g yacc.
- Write expression syntac recursively to express evaluation order
and precedence syntactically.
- Organized open issues list, folded in stuff from todo.txt which
is now obsolete.
