A FlagSet is an independent set of flags that may be used,
for example, to provide flag processing for subcommands
in a CLI. The standard, os.Args-derived set of flags is a
global but non-exported FlagSet and the standard functions
are wrappers for methods of that FlagSet.
Allow the programmer to control whether the program
exits if there is a parse error. For the default set, the behavior
remains to exit on error.
The handling of Usage is odd due to backward compatibility.

A user pointed out that Go didn't work with their
corp proxy, always throwing 400 Bad Request errors.
Looking at the RFC 2616, Host is always required,
even with proxies.
The old code assumed that writing an absolute URL
in the first line of an HTTP request implied
that the Host header was no longer necessary.

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.

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).

On my laptop, I had an 800x600 jpeg and an 800x600 png (with
transparency). I timed how long it took to draw each image onto an
equivalently sized, zeroed RGBA image.
Previously, the jpeg took 75ms and the png took 70ms, going through
the medium-fast path, i.e. func drawRGBA in draw.go.
After this CL, the jpeg took 14ms, and the png took 21ms with the
Over operator and 12ms with the Src operator.
It's only a rough estimate basd on one image file, but it should
give an idea of the order of magnitude of improvement.
