Similar to what is done already for RCPT TO, the code now checks for and
adds angle brackets (<>) around the email address that is provided for
CURLOPT_MAIL_RCPT unless the app has done so itself.

Without this you won't get the next (Subject) line.

sorted to reflect same internal order as the one shown
in the usage message.

if add2list() returns an error, bail out!

Make sure that Curl_cache_addr() errors are propagated to callers of
loadhostpairs().

(this loadhostpairs function caused a scan-build warning due to the
'dns' variable getting assigned but never used)

Default libcurl's file names are kept equal to those used since Y2K.

Doing curlx_strtoofft() on the size just to figure out the end of it
causes a compiler warning since the result wasn't used, but is also a
bit of a waste.

Since the original `conn' pointer was used after the `connectdata' it
points to has been closed/cleaned up by Curl_reconnect_request it caused
a crash. We must make sure to use the newly created connection instead!

Make the c-ares resolver code ask for both IPv4 and IPv6 addresses when
IPv6 is enabled.

This is a workaround for the missing ares_getaddrinfo() and is a lot
easier to implement.

Note that as long as c-ares returns IPv4 addresses when IPv6 addresses
were requested but missing, this will cause a host's IPv4 addresses to
occur twice in the DNS cache.

This example shows how to send SMTP with TLS

Add a simple SMTP example program, patterned after some of the existing
examples, and the curl application.

This version addresses issues raised by David Woodhouse on comments in
the simplesmtp.c example.

Bug: http://curl.haxx.se/mail/lib-2010-12/0192.html

The SSL_SERVER_VERIFY_LATER bit in the ssl_ctx_new() call allows the
code to verify the peer certificate explicitly after the handshake and
then the "data->set.ssl.verifypeer" option works.

When no explicit version is selected we should try to use whatever is
best for us, and in the axTLS case that means TLSv1.

Removed trailing whitespace
Removed several compiler warnings
Removed odd backslashes at some line endings

The public axTLS header (at least as of 1.2.7) redefines the memory
functions. We #undef those again immediately after the public header to
limit the damage. This should be fixed in axTLS.

In tradition with other options, have this point to the directory prefix
and not the lib directory. Otherwise we can't set the include path
reliably.

Failed HTTPS tests: 301, 306, 311, 312, 313, 560
311, 312 need more detailed error reporting from axTLS.
313 relates to CRL, which hasn't been implemented yet.

Added axTLS to autotool files and glue code to misc other files.
axtls.h maps SSL API functions, but may change.
axtls.c is just a stub file and will definitely change.
