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").

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.

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.

writing the idct result directly to the image buffer instead of
storing it in an intermediate d.blocks field.

Writing to d.blocks was necessary when decoding to an image.RGBA image,
but now that we decode to a ycbcr.YCbCr we can write each component
directly to the image buffer.

Crude "time ./6.out" scores to decode a specific 2592x1944 JPEG 20
times show a 16% speed-up:
