9346c6d901 make every func literal expression allocate, 
so that == on func means that the
functions originated in the same
execution of a func literal or definition.

before, there was an inconsistency:

	func() {x++} != func() {x++}

but

	func() {} == func() {}

this CL makes the second case != too,
just like

	make(map[int]int) != make(map[int]int)

2210a643b7 Intersperse comments nicely when printing an AST. 
gofmt formatted source code looks pretty good already;
with a bit more fine-tuning it should be great.

printer.go:
- Implemented comment intersperse algorithm.
  The approach is a result of many trial-and-error
  experiments but at this point reasonably simple
  and open to arbitrary fine-tuning.

parser.go:
- Simplified handling of lead and line comments
  (formerly called leading and trailing comments).
- Use a comments list instead of an array (I may
  change this back - this is not obviously better
  and uses more space).

doc.go:
- Remove comments from AST nodes that have been
  'consumed' in the documentation to avoid duplicate
  printing of them. Allows for better control of
  what is printed w/o use of printing control flags
  (which are hard to use and not fine-grained enough).

Corresponding adjustments to various clients of these
files.

6d3d25de21 Ring ADT. 
- Provides analogous functionality to a doubly-linked list
  implementation.
- Completely symmetric set of operations.
- Operations on the ADT do not lead to results that are
  outside the domain of the ADT (closed interface).
- Alternative to container/list.

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

aa1e8064b2 change HTTP access for RPC. 
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.

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.
