...as it is no longer required following capability and authentication
changes and is now causing problems following commit 49341628 as
the test number is obtained from the client address in the EHLO.

...to the client address as this frees the RCPT strings to contain
just an email address and by passing the test number into curl as the
client address remains consistent with POP3 and IMAP tests as they are
specified in the URL.

The comment mentioned the need to free the data, but the example already
does that free

This is similar to getinmemory.c but with an initial POST.

If no WINVER and/or _WIN32_IWNNT define was set, the Windows platform
SDK often defaults to high value, e.g. 0x601 (whoch may probably depend
on the Windows version being used, in my case Windows 7).

If WINVER >= 0x600 then winsock2.h includes some defines for WSAPoll(),
e.g. POLLIN, POLLPRI, POLLOUT etc. These defines clash with cURL's
lib/select.h.

Make sure HAVE_STRUCT_POLLFD is defined then.

There is an implicit conversion from "unsigned long" to "long"

Moved the standard SASL mechanism strings into curl_sasl.h rather than
hard coding the same values over and over again in the protocols that
use SASL authentication.

For more information about the mechanism strings see:

...from commit f81d1e16 due to copy paste error.

As someone reported on the mailing list a while back, the hard-coded
arbitrary timeout of 7s in test 1112 is not sufficient in some build
environments. At Arista Networks we build and test curl as part of our
automated build system, and we've run into this timeout 170 times so
far. Our build servers are typically quite busy building and testing a
lot of code in parallel, so despite being beefy machines with 32 cores
and 128GB of RAM we still hit this 7s timeout regularly.

RCPT_smtp() will now check for a correctly formatted TO address which
allows for invalid recipient addresses to be added.

As curl will send a HELO command after an negative EHLO response, added
the same detection from commit b07709f7 to the HELO handler to
ensure the test server is identified correctly and an upload isn't
performed.

Rather than detecting the TO address as missing in the DATA handler,
moved the detection to the RCPT command handler where an error response
can be generated.

Somehow commit 60a20461 missed the last item in the sync list
even though I'm sure I added it during editing.

Added missing information, from curl 7.31.0, regarding the use of the
optional login options that may be specified as part of --user.

For example:

--user 'user:password;auth=NTLM' in IMAP, POP3 and SMTP protocols.

Moved the special SMTP server detection code from the DATA command
handler, which happens further down the operation chain after EHLO,
MAIL and RCPT commands, to the EHLO command as it is the first command
to be generated by a SMTP operation as well as containing the special
"verifiedserver" string from the URL.

This not only makes it easier and quicker to detect but also means that
cURL doesn't need to specify "verifiedserver" as --mail-from and
--mail-rcpt arguments.

More importantly, this also makes the upcoming verification changes to
the RCPT handler easier to implement.

In ossl_connect_step2() when the "Unknown SSL protocol error" occurs, it
would output the local port number instead of the remote one which
showed when doing SSL over a proxy (but with the correct remote host
name). As libcurl only speaks SSL to the remote we know it is the remote
port.

The libcurl date parser returns INT_MAX for all dates > 2037 so this
test is now made to use 2037 instead of 2038 to work the same for both
32bit and 64bit time_t systems.

...in preparation of upcoming multiple recipient tests.
