cdbed823bd cmd/go: solve ambiguity of get lp.net/project/foo 
This solves the ambiguity for "lp.net/project/foo". In these URLs,
"foo" could be a series name registered in Launchpad with its own
branch, and it could also be the name of a directory within the
main project branch one level up.

Solve it by testing if the series branch exists in Launchpad
and if it doesn't moving the root one level up.

899cd04e21 net/http: add Request.RequestURI field 
The new url.URL's parsing can be too canonicalizing for
certain applications. By keeping the original request URI
around, we give applications a gross escape hatch while
keeping the URL package clean and simple for normal uses.

(From a discussion with Gary Burd, Gustavo Niemeyer,
and Russ Cox.)

71b1c6d3c9 godoc: move overview before API TOC 
Compare:
http://swtch.com/junk/regexp0.html [old]
http://swtch.com/junk/regexp.html [new]

Especially for packages with large APIs, this makes the
overview more promiment, so that it can give the appropriate
context for reading the API list.  This should help significantly
in packages with large APIs, like net, so that the first thing users
see is not a jumble of functions but an introduction to the package.

5c04272ff3 cmd/goapi: new tool for tracking exported API over time 
The idea is that we add files to the api/ directory which
are sets of promises for the future.  Each line in a file
is a stand-alone feature description.

When we do a release, we make sure we haven't broken or changed
any lines from the past (only added them).

We never change old files, only adding new ones. (go-1.1.txt,
etc)

d571c5ca78 go/doc: revert API change (per former discussion) and cleanup 
Separating Method from Func made the code only more complicated
without adding much to the useability/readability of the API.
Reverted to where it was, but leaving the new method-specific
fields Orig and Level.

Former clients (godoc) of doc.Method only used the Func fields;
and because Func was embedded, no changes are needed with respect
to the removal of Method.

Changed type of Func.Recv from ast.Expr to string. This was a
long-standing TODO. Also implemented Func.Orig field (another TODO).

No further go/doc API changes are expected for Go 1.

9d4ae0ae5c gofix: handle xml.Unmarshal in xmlapi fix 
This improves the handling of xml.Unmarshal in
the xmlapi fix by guessing some of the common
types used on it.

This also fixes a bug in the partial typechecker.
In an expression such as f(&a), it'd mark a as
having &T rather than *T.

ee9bfb023a gc: fix order of evaluation 
Pulling function calls out to happen before the
expression being evaluated was causing illegal
reorderings even without inlining; with inlining
it got worse.  This CL adds a separate ordering pass
to move things with a fixed order out of expressions
and into the statement sequence, where they will
not be reordered by walk.

Replaces lvd's CL 5534079.

Fixes #2740.
