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").

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
the use of reflection.

There were a couple issues:
-- HEAD requests were attempting to be ungzipped,
despite having no content. That was fixed in
the previous patch version, but ultimately was
fixed as a result of other refactoring:
-- persist.go's ClientConn "lastbody" field was
remembering the wrong body, since we were
mucking with it later. Instead, ditch
ClientConn's readRes func field and add a new
method passing it in, so we can use a closure
and do all our bodyEOFSignal + gunzip stuff
in one place, simplifying a lot of code and
not requiring messing with ClientConn's innards.
-- closing the gzip reader didn't consume its
contents. if the caller wasn't done reading
all the response body and ClientConn closed it
(thinking it'd move past those bytes in the
TCP stream), it actually wouldn't. so introduce
a new wrapper just for gzip reader to have its
Close method do an ioutil.Discard on its body
first, before the close.

RFC 6265 requires that user agents MUST NOT send more than
one Cookie header in a request.
Note, this change also fixes an issue when sending requests
with more than one cookie header line to a php script served
by an apache web server. Apache concatenates the cookies
with ", ", but php tries to split them only at ";". E.g.
two cookies: "a=b, c=d" are seen by php as one cookie "a"
with the value "b, c=d".

An optimization in Transport which re-uses TCP
connections early in the case where there is
no response body interacted poorly with
ErrBodyReadAfterClose. Upon recycling the TCP
connection early we would Close the Response.Body
(in case the user forgot to), but in the case
of a zero-lengthed body, the user's handler might
not have run yet.
This CL makes sure the Transport doesn't try
to Close requests when we're about to immediately
re-use the TCP connection.
This also includes additional tests I wrote
while debugging.

So far, only top-level names where considered when trimming ASTs
using a filter function. For instance, "godoc reflect Implements"
didn't show the "Implements" method of the type Interface because
the local method name was not considered (on the other hand, "top-
level" declared methods associated with types were considered).
With this CL, AST filter functions look also at struct fields
and interface methods.
