This extends the fix from commit d7934b8bd4
When the multi state is changed within the multi_runsingle from DOING to
DO_MORE, we didn't immediately start the FTP state machine again. That
then left the FTP state in FTP_STOP. When curl_multi_fdset() was
subsequently called, the ftp_domore_getsock() function would return the
wrong fd info.

When running torture tests, verify before each test case that required
pingpong servers which are supposed to be alive are actually responsive.
If found not responsive then restart them.
EPRT is now supported by default by the server. To disable it, use the
generic REPLY instruction in the <servercmd> tag. Test 116 now has it
disabled. All other existing active FTP port tests strip out the port
commands from the logs already so the change of the server isn't that
noticable.
As commit 5850cc4808 clarifies, libcurl can deliver header lines that
are longer than CURL_MAX_WRITE_SIZE, only body data is limited to that
size. The curl tool has check (when built debug-enabled) that made the
wrong checks and this new test 1205 verifies that larger headers work.
Added pop3 username and password example as well as an explanation of
how path part of the URL is used under pop3.
Additionally have corrected a couple of typos.
After a PORT has been issued, and the multi handle would switch to the
CURLM_STATE_DO_MORE state (which is unique for FTP), libcurl would
return the wrong fdset to wait for when curl_multi_fdset() is
called. The code would blindly assume that it was waiting for a connect
of the second connection, while that isn't true immediately after the
PORT command.
Also, the function multi.c:domore_getsock() was highly FTP-centric and
therefore ugly to keep in protocol-agnostic code. I solved this problem
by introducing a new function pointer in the Curl_handler struct called
domore_getsock() which is only called during the DOMORE state for
protocols that set that pointer.
The new ftp.c:ftp_domore_getsock() function now returns fdset info about
the control connection's command/response handling while such a state is
in use, and goes over to waiting for a writable second connection first
once the commands are done.
The original problem could be seen by running test 525 and checking the
time stamps in the FTP server log. I can verify that this fix at least
fixes this problem.

The fix is pretty much the one Nick Zitzmann provided, just edited to do
the right indent levels and with test case 1204 added to verify the fix.

The default lowat level for gnutls-2.12* is set to zero to avoid
unnecessary system calls and the gnutls_transport_set_lowat function has
been totally removed in >=gnutls-3 which causes build failures.
Therefore, the function shouldn't be used except for versions that
require it, <gnutls-2.12.0.
Previously the bit was set before the connection was found working so if
it would first fail to an ipv6 address and then connect fine to a IPv4
address the variable would still be TRUE.

Previously we required that -S/--show-error was used _after_
-s/--silent. This was slightly confusing since we strive to make
arguments as position independent as possible.
Now, you can use them in any order and the result should still be the
same.

When doing a multipart formpost with a read callback, and that callback
returns CURL_READFUNC_ABORT, that return code must be properly
propagated back and handled accordingly. Previously it would be handled
as a zero byte read which would cause a hang!
Added test case 587 to verify. It uses the lib554.c source code with a
small ifdef.

There might be situations where a user would want to unset this option.
Avoid forcing him/her to cast the NULL argument to (char *) in order to
get past the compile time typecheck.
Save the errno value immediately after a connect() failure so that it
won't get reset to something else before we read it.

When, for a given test, server is instructed to close connection after
server reply we now wait a very small amount of time (50ms) before doing
so. This is done to allow client to, at least partially, read server
reply before getting an ECONNRESET.
The above is required to make test cases 1070, 1200, 1201 and 1202 pass
with Cygwin 1.5.X on W2K.
GOPHER test server closes connection after _every_ server-reply, as such,
at some point it could require a bigger time or using shutdown() before
a server-side initiated disconnection.
