Rodric provide an awesome recipe that proved libcurl didn't timeout at
the requested time - it instead often timed out at [connect time] +
[timeout time] instead of the documented and intended [timeout time]
only. This bug was due to the code using the wrong base offset when
comparing against "now". I could also take the oppurtinity to simplify
the code by properly using of the generic help function for this:
Curl_timeleft.

Bug: http://curl.haxx.se/bug/view.cgi?id=3061535
As this function uses return code 0 to mean that there is no timeout, it
needs to check that it doesn't return a time left value that is exactly
zero. It could lead to libcurl doing an extra 1000 ms select() call and
thus not timing out as accurately as it should.
I fell over this bug when working on the bug 3061535 but this fix does
not correct that problem alone, although this is a problem that needs to
be fixed.

1. Remove the comment warning that it's "not been verified to work". It
works with no problems in my testing.
2. Remove 2 unnecessary includes.
3. Remove the myrealloc(). Initialize chunk.memory with malloc() instead
of NULL. The comments for these two parts contradicted each other.
4. Handle out of memory from realloc() instead of continuing.
5. Print a brief status message at the end.
The timeout is set for the connect phase already at the start of the
request so we should not add a new one, and we MUST not set expire to 0
as that will remove any other potentially existing timeouts.
When curl calls a function from that library then it needs to
explicitly link to the library instead of piggybacking on
libcurl's own dependency. Without this, GNU ld with the
--no-add-needed flag fails when linking (which Fedora now does
by default).

The code reading chunked encoding attempts to rewind the code if it had
read more data than the chunky parser consumes. The rewinding can fail
and it will then cause an error. This change now makes the rewinding
only happen if pipelining is in use - as that's the only time it really
needs to be done.

Curl_getconnectinfo() is changed to return a proper curl_socket_t for
the last socket so that it'll work more portably (and cause less
compiler warnings).
Add a timeout check for handles in the state machine so that they will
timeout in all states disregarding what actions that may or may not
happen.
Fixed a bug in socket_action introduced recently when looping over timed
out handles: it wouldn't assign the 'data' variable and thus it wouldn't
properly take care of handles.
In the update_timer function, the code now checks if the timeout has
been removed and then it tells the application. Previously it would
always let the remaining timeout(s) just linger to expire later on.
Each easy handle has a list of timeouts, so as soon as the main timeout
for a handle expires, we must make sure to get the next entry from the
list and re-add the handle to the splay tree.
This was attempted previously but was done poorly in my commit
232ad6549a.
When a new transfer is about to start we now set the proper timeouts to
expire for the multi interface if they are set for the handle. This is a
follow-up bugfix to make sure that easy handles timeout properly when
the times expire and the multi interface is used. This also improves
curl_multi_timeout().
Fixed some issues that caused xmllint failures, added features
and keywords, fixed some quotes and removed some <strip> sections
that unnecessarily limited test checking.
Introduced in the initial gopher commits, there was added logic to do
GOPHER test serving in the pingpong server but as it resembles HTTP much
more than FTP or SMTP, the gopher testing has been moved over to instead
use the sws (HTTP) server. This change simply removes unused code.
