This is Go 1 package renaming CL #3.
This one merely moves the source; the import strings will be
changed after the next weekly release.
This one moves pieces into net.

http -> net/http
http/cgi -> net/http/cgi
http/fcgi -> net/http/fcgi
http/pprof -> net/http/pprof
http/httptest -> net/http/httptest
mail -> net/mail
rpc -> net/rpc
rpc/jsonrpc -> net/rpc/jsonrpc
smtp -> net/smtp
url -> net/url

Also remove rand (now math/rand) from NOTEST - it has a test.

The only edits are in Makefiles and deps.bash.

Change the signature of Split to have no count,
assuming a full split, and rename the existing
Split with a count to SplitN.
Do the same to package bytes.
Add a gofix module.

Previously Request and Response had redundant fields for
Referer, UserAgent, and cookies which caused confusion and
bugs.  It also didn't allow us to expand the package over
time, since the way to access fields would be in the Headers
one day and promoted to a field the next day.  That would be
hard to gofix, especially with code ranging over Headers.

After a discussion on the mail package's design with a similar
problem, we've designed to make the Headers be the source of
truth and add accessors instead.

Request:
change: Referer -> Referer()
change: UserAgent -> UserAgent()
change: Cookie -> Cookies()
new: Cookie(name) *Cookie
new: AddCookie(*Cookie)

Response:
change: Cookie -> Cookies()

Cookie:
new: String() string

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()

Also don't serialize empty headers.

R=dsymonds, rsc

https://golang.org/cl/4275045

Caller code needs to change:

rw.SetHeader("Content-Type", "text/plain")
to:
rw.Header().Set("Content-Type", "text/plain")

This now permits returning multiple headers
with the same name using Add:

rw.Header().Add("Set-Cookie", "..")
rw.Header().Add("Set-Cookie", "..")

This patch also fixes serialization of headers, removing newline characters.

Compliance issue addressed here: POST requests carrying form data are required
to use "identity" transfer encoding by common nginx and apache server configurations,
e.g. wordpress.com (and many others). So, Request needed to be able to send
non-chunked encodings.

Thus, Request is extended to support identity and chunked encodings, like
Response.  Since the Read() and Write() logic are shared by both (and are
quite long), it is exported in a separate file transfer.go.

(1) http.Response must close resp.Body after writing.
(2) Case when resp.Body != nil and resp.ContentLength = 0 should not be
treated as an error in Response.Write, because this is what
ReadResponse often returns.
(3) Changed body.th to body.hdr for readability.
