e211dfb000 refactor/rename: fix crash with "." as -from package
Cause: the absolute cwd, not ".", must be passed to build.Import.

Also: simplify the lookup logic in findFromObjects, and handle nil
gracefully.

(No unit test---not worth faking os.Getwd.)

Fixes issue #13866

542ffc7e75 tools: switch to standard go/types at tip
A few files have been forked and tagged "go1.5,!go1.6" to work around
minor API changes between the two types packages:
- constant.Value.String() in oracle/describe.go and its tests;
- constant.ToInt must now be called before constant.Int64Val.
- types.Config{Importer: importer.Default()} in a number of places
- go/types/typeutil/import_test.go uses lowercase names to avoid 'import "C"'.

Files in go/types/typesutil, missing from my previous CL, have been
tagged !go1.5; these files will be deleted in February.

All affected packages were tested using 1.4.1, 1.5, and ~1.6 (tip).

2477c0d578 x/tools/...: fork and tag !1.5 all files that use go/types et al
This change will ensure that the tree continues to work with go1.4.1.

All files continue to depend on golang.org/x/tools/go/types, but in a
follow-up change, I will switch the primary files to depend on the
standard go/types package.  Another (smaller) set of files will be
forked and tagged, this time !1.6, due to API differences between the
two packages.

All tests pass using 1.4.1, 1.5, and ~1.6 (tip).

03e05ec5a5 refactor/rename: eliminate dependency on refactor/lexical package
so that we can delete that package.

lexicalLookup reconstructs the lexical scope from the existing tree of
types.Scope blocks, using source position information to determine
which prefix of declarations are visible.  (Inspired by Russ's
lookupAtPos in github.com/rsc/grind/grinder.)

forEachLexicalRef implements the part of the recursion from
refactor/lexical that enumerates the ast.Idents that use lexical
lookup.  (I would still like to eliminate this redundant logic by
having go/types record environments, as in CL 9493.)

9c7ccd869c refactor/rename: emacs: kill go-rename buffer correctly
Match gofmt's behaviour of closing the status buffer. Don't display the
buffer in case of success as we were going to hide it instantly again,
anyway. Also, instead of using delete-window, use
gofmt--kill-error-buffer. gofmt--kill-error-buffer uses quit-window if
there's a window for the buffer, kill-buffer otherwise.

quit-window only deletes the window if it was created explicitly for the
status buffer and if it is still displaying it. This way, we won't close
windows that the user created or repurposed himself.

Additionally, this change ensures that we don't leave a *go-rename*
buffer lying around when gorename succeeded.

Fixes golang/go#10972.

0dda50d42a go/loader: improve robustness in face of input errors

    Also: redesign the tests and add many new cases.

c6ec5ea66d cmd/gorename: support renaming of methods with consequences for other types, iff initiated at an abstract method.
Previously, gorename rejected all method renamings if it would
change the assignability relation.

Now, so long as the renaming was initiated at an abstract
method, the renaming proceeds, changing concrete methods (and
possibly other abstract methods) as needed.  The user
intention is clear.

The intention of a renaming initiated at a concrete method is
less clear, so we still reject it if it would change the
assignability relation.  The diagnostic advises the user to
rename the abstract method if that was the intention.

Additional safety checks are required: for each
satisfy.Constraint that couples a concrete type C and an
interface type I, we must treat it just like a set of implicit
selections C.f, one per abstract method f of I, and ensure the
selections' meanings are unchanged.

The satisfy package no longer canonicalizes types, since this
substitutes one interface for another (equivalent) one, which
is sound, but makes the type names random and the error
messages confusing.

Also, fixed a bug in 'satisfy' relating to map keys.

+ Lots more tests.

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.
