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.

- 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.

breakpoints get installed and uninstalled. We also don't try
to detach from them, since that will fail.

container for values.
Instead of having one evaluator function that returns a
generic Value, there is now an evaluator function for each
generalized type that simply returns a native type.
The compiler is more type-safe now because there are almost no
type conversions at evaluation time and it's impossible to
invoke a nil evaluator function during evaluation. This also
makes ideals and pointers really clean.
As an added bonus, expression evaluation should be faster
because it doesn't require heap allocation for every
intermediate value, type switches, or lots of conversions to
and from Value. It also involves fewer function calls.

1. use CONNECT instead of GET.
CONNECT has exactly the meaning
we want; most of the time people
connect to ip:port; we're connecting
to /_goRPC_
2. wait for a successful HTTP response
before assuming we are connected to
the RPC protocol. this allows better
error reporting and also keeps the
protocol alternating between speakers,
so that the buffering in the HTTP request
reader cannot accidentally eat some
RPC bytes too.
gotest sometimes hangs, but not in HTTP.
gotest -match=Unknown hangs every few runs
even in a clean client.
