The 'parents' field is documented to be blank if there's only one
simple parent. We want 'p1node', which is the hex commit of the
first parent.

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.

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.

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.

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.

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.

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

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.

Improve the generated code by using a const instead of a var for the names string.
This requires some refactoring to get neat const() and var() blocks.
Also change the generate map code go use a single sliced string, to reduce the
size of the compiled representation (only one string value).
