Fixes#2140.
The http.DefaultTransport's RoundTrip method leaves the http.Request object
in an altered state after performing the round trip. This patch removes
the header from the Request before returning to the client.

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()

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.

Amazon S3 sends Transfer-Encoding "chunked"
on its 404 responses to HEAD requests for
missing objects.
We weren't ignoring the Transfer-Encoding
and were thus interpretting the subsequent
response headers as a chunk header from the
previous responses body (but a HEAD response
can't have a body)

A connection shouldn't be made available
for re-use until its body has been consumed.
(except in the case of pipelining, which isn't
implemented yet)
This CL fixes some issues seen with heavy load
against Amazon S3.
Subtle implementation detail: to prevent a race
with the client requesting a new connection
before previous one is returned, we actually
have to call putIdleConnection _before_ we
return from the final Read/Close call on the
http.Response.Body.

The transport readLoop was waiting forever for the client to
read the non-existent body before proceeding to read the next
request.

This patch adds a connection cache and keep-alive
support to Transport, which is used by the
HTTP client.
It's also structured such that it's easy to add
HTTP pipelining in the future.

Transport.Do -> RoundTripper.RoundTrip
This makes way for a subsequent CL to export the
currently private RoundTripper implementation
as struct Transport.
