74021b4175 cmd/gorename: a precise, type-aware renaming tool for Go identifiers.
See the usage message in main.go for orientation.

To the best of my knowledge, the tool implements all required
soundness checks, except:
- the dynamic behaviour of reflection is obviously undecidable.
- it rejects method renamings that change the "implements" relation.
  It should probably be more aggressive.
- actually it only checks the part of the "implements" relation
  needed for compilation.  Understanding the dynamic behaviour
  of interfaces is obviously undecidable.
- a couple of minor gaps are indicated by TODO comments.

Also:
- Emacs integration.
- tests of all safety checks and (some) successful rewrites.

- ParseFile (core of go/loader's parseFiles(); also used by refactor/rename)
- ContainingPackage (core of Oracle's guessImportPath; also used by refactor/rename)
- Accessors for effective "methods" of build.Context:
  FileExists, OpenFile, IsAbsPath, JoinPath.

c90cb9e042 refactor/satisfy: enumerate interface satisfaction constraints induced by Go syntax.
The type checker does not currently report the set of pairs of
types that are tested for assignability (though gri and I
agree that it should).  This information is useful for many
applications.  For example, refactoring tool needs to know the
minimal set of interface satisfaction constraints that must be
preserved during a refactoring.

This package is a stopgap measure to deduce the same
information using another pass.  Unlike go/types, it is not
robust against inputs containing type errors.

897f6677ae refactor/lexical: understand the structure of the lexical environment.
The Uses, Defs and Scope information provided by go/types is
inadequate for answering "what if?" queries about the
structure of the lexical environment.

In this code, for example,

        var x int

        func f() {
                print(x)
                x := ""
                print(x)
        }

the two referring Idents x appear at the same lexical depth,
inside the function f's Scope object, yet they resolve to
different objects.

This package associates a lexical.Environment instance with
every reference to capture these differences.  Each
environment is a linked list of enclosing Blocks, and for each
block, a number indicating what prefix of its bindings are
visible.  (Zero for the first 'x' reference above, 1 for the
second.)

+ Smoke test over stdlib.

This functionality could be integrated with the type checker
in lieu of the not-so-useful types.Info.Scopes data, at little
extra cost in code or in running time/space.  We should talk
about that.

ebc87c5c5e godoc: fix bug in "internal call graph" tree widget.
Today I learned that getElementByClass returns an
HTMLContainer, not an array, so the for loop was iterating its
properties, which include:
- the methods of the type, which were filtered out by the condition;
- the array-like integer indices of the elements, which we want;
- the ids of the same elements (!), which we weren't expecting.
The net result is that various functions were called twice,
causing the tree to be double-populated and clicks to cause
and expand+collapse.

It's a miracle to me that any JS program even approximately works.

85a9565822 go/ssa: fix bug causing (manual) go/pointer stdlib test to crash.
The needMethods cache logic was wrong: it would treat any
previous call as a cache hit, even if 'skip' was true for that
call.  As a result it could fail to generate methods for some
'skip' types, i.e. anonymous structs.

6c93dbff3e go.tools/godoc: deal with fallout from $GOROOT/src/pkg -> $GOROOT/src renaming.
To avoid breaking URLs, we redirect /src/pkg/* to /src/*.

The URL /pkg is now the "directory" /src, which triggers the
"Packages" index.

All other references to "src/pkg" are now gone,
except a number in the namespace documentation which are
probably still illustrative.

Tested: go test cmd/godoc godoc
        Manual inspection of src and src/pkg pages.
        with GOROOT and GOPATH packages
        -analysis
        /AUTHORS file URL still works

77b9ff6df3 go.tools/go/buildutil: AllPackages: enumerate all packages in a Go workspace.
This function has been copied at least 6 times throughout
go.tools.  This implementation is superior since it does
all I/O through the virtualized go/build file system, and it
is highly parallel (and much faster).

We expose two flavours, simple (for existing tests) and
parallel (for high-performance tools such as gorename).

This CL creates the go/buildutil package, which is intended for
utilities related to go/build.
