3d42e691b9 make 6l produce dynamically linked binaries (although they are fully statically linked as far
as go is concerned).  the -d flag is now flipped; as on the mac, -d disables dynamic.

much remains to be improved to move the output closer to the gcc format.

e52e9ca82e another step toward eliminating forward declarations.
introduce NodeList* type in compiler to replace OLIST.
this clarifies where lists can and cannot occur.
list append and concatenation are now cheap.
the _r rules are gone from yacc.
rev and unrev are gone.
no more lists of lists.

the representation of assignments is a bit clunkier.
split into OAS (1=1) and OAS2 (2 or more on one side).

delete dead chanrecv3 code.

delay construction of func types.

f3ffd93a61 ast:
- renamed Program -> SourceFile
- added Package node representing the AST for an entire package
- added filter function to create a source file mimicking the
  interface of an entire package

parser:
- parser entry to parse entire packages
- unified naming of parser entry points
- factored out entry points into new file (interface.go)

gofmt:
- extended to accept single .go files, and package paths:
  gofmt file.go	     	    // formatting of a single file
  gofmt -x file.go	    // interface of a single file
  gofmt -x ./MyPackage	    // interface of a local package
  gofmt -x math		    // interface of a $GOROOT relative package

Various adjustments in dependent files, documentation.

0dadc4fe4f cleanup in preparation for new scoping.
walkstate -> walkstmt
walktype -> walkexpr; stmts moved to walkstmt

walktype and friends have a final Node **init
argument that can have side effects appended,
making it more explicit when they do and do not happen.
this replaces the old global addtop and addtotop.

delete switch map and interface conversion cases
(dropped from the language months ago).

903d28bd1e ANY is already checked separately,
so remove code from go.y.

show original types in badtype; don't remove pointers.
not sure why this was here but it confuses things
if the bad part involves two named pointer types
with different names but the same pointed-at type.
