The position (type) for which the "invalid cycle" error
message is reported depends on which type in a cycle of
types is first checked. Which one is first depends on
the iteration order of maps which is different on
different platforms. For now, disable this error message.

At the moment types.Check() only deals with global
types and only partially so. But the framework is
there to compute them and check for cycles. An initial
type test is passing.

First step of a series of CLs to come.

This uses a fully custom function for indenting Go code in Vim.
It provides a lot more flexibility than a cindent-based approach,
so this version gets the := operator correct, as well as switch
labels and jump labels.

One outstanding TODO is to handle lines immediately after jump labels.

HEAD requests should in my opinion have the ability to follow redirects
like the implementation of GET requests does. My use case is polling
several thousand severs to check if they respond with 200 status codes.
Using GET requests is neither efficient in running time of the task nor
for bandwidth consumption.

This suggested patch changes the return signature of http.Head() to match
that of http.Get(), providing the final URL in a redirect chain.

`curl -IL http://google.com` follows redirects with HEAD requests just fine.

Fixes #1806.

This CL:

-- removes Response.RequestMethod string
-- adds Response.Request *Request
-- removes the finalURL result parameter from client.Get()
-- adds a gofix rule for callers of http.Get which assign
   the final url to the blank identifier; warning otherwise

Caller who did:

res, finalURL, err := http.Get(...)

now need to do:

res, err := http.Get(...)
if err != nil {
   ...
}
finalURL := res.Request.URL.String()

The TIFF spec says that a baseline TIFF reader must gracefully terminate
when the image has a SampleFormat tag which it does not support.
For baseline compatibility, only SampleFormat=1 (the default) is needed.
Images with other sample formats (e.g. floating-point color values)
are very rare in practice.

This CL proposes some subtle language changes
in an attempt to clarify the semantics of range
clauses and simplify uses of maps.

- nil maps behave like empty maps; but attempting
  to set a value in a nil map causes a run-time panic
- nil channels are never ready for communication;
  sending or reading from a nil channel blocks forever
- if there is only one index iteration variable in a
  range clause and len(range expression) would be a constant,
  the range expression is not evaluated.
  (was discrepancy with len/cap before)
- the notion of what is a constant expression len(x)
  for (pointer to) arrays x has been generalized and
  simplified (can still be syntactically decided)
  (before: more restrictive syntactic rule that was not
  consistently implemented)

Fixes #1713.

A struct or interface type node is marked incomplete if fields or
methods have been removed through any kind of filtering, not just
because entries are not exported.

The current message was misleading in some cases (for instance:
"godoc -src reflect Implements").

Also:

Partially revert CL 4518050. In go/doc.go, instead of calling the go/ast filter
functions, implement the corresponding match functions that do no remove
declaration elements.

In the new world, one builder runs
        gobuilder -commit
which uploads information about commits to the dashboard,
which then hands the work out to the builders by hash.
There is no assumption anymore that the commit numbers
are consistent across builders.

New builders will need to be deployed.  For now darwin-amd64
is running the new builder to test the code.

The new JSON-based protocol for handing out work via /todo
should be easy to extend if we want to add support for sending
trial CLs to the builders.

This code is already running on godashboard.appspot.com.

This was causing a panic in the reflect package
since type.* pointers with their low bits set are
assumed to have certain flags set that disallow
