We force runtime.GC before WriteHeapProfile with -test.heapprofile.
Make it possible to do the same with the HTTP interface.
Some servers only run a GC every few minutes.
On such servers, the heap profile will be a few minutes stale,
which may be too old to be useful.
Requested by private mail.

The http package by default adds "Accept-Encoding: gzip" to outgoing
requests, unless it's a bad idea, or the user requested otherwise.
Only when the http package adds its own implicit Accept-Encoding header
does the http package also transparently un-gzip the response.
If the user requested part of a document (e.g. bytes 40 to 50), it appears
that Github/Varnish send:
range(gzip(content), 40, 50)
And not:
gzip(range(content, 40, 50))
The RFC 2616 set of replacements (with the purpose of
clarifying ambiguities since 1999) has an RFC about Range
requests (http://tools.ietf.org/html/rfc7233) but does not
mention the interaction with encodings.
Regardless of whether range(gzip(content)) or gzip(range(content)) is
correct, this change prevents the Go package from asking for gzip
in requests if we're also asking for Range, avoiding the issue.
If the user cared, they can do it themselves. But Go transparently
un-gzipping a fragment of gzip is never useful.

http.Client calls URL.String() to fill in the Referer header, which may
contain authentication info. This patch removes authentication info from
the Referer header without introducing any API changes.
A new test for net/http is also provided.
This is the polished version of Alberto García Hierro's
https://golang.org/cl/9766046/
It should handle https Referer right.

Bodies larger than 8KB (the default bufio reader size) weren't
being dumped. Force a read of the body so they're teed into
the response buffer.
Thanks to Steven Hartland for identifying the problem.

See comment 4 of https://code.google.com/p/go/issues/detail?id=8483#c4:
"So if a user creates a http.Client, issues a bunch of
requests and then wants to shutdown it and all opened connections;
what is she intended to do? The report suggests that just waiting for
all pending requests and calling CloseIdleConnections won't do, as
there can be new racing connections. Obviously she can't do what
you've done in the test, as it uses the unexported function. If this
happens periodically, it can lead to serious resource leaks (the
transport is also preserved alive). Am I missing something?"
This CL tracks the user's intention to close all idle
connections (CloseIdleConnections sets it true; and making a
new request sets it false). If a pending dial finishes and
nobody wants it, before it's retained for a future caller, the
"wantIdle" bool is checked and it's closed if the user has
called CloseIdleConnections without a later call to make a new
request.
