Just showing how to download the contents of a given URL into a local
file.

Based on a suggestion and example code by Georg Potthast

Just to show that IMAP is used just like other protocols

This newly speced HTTP status code already works as intended in the new
spec:

Test 1325 is added to verify that the method is kept after the redirect

Some functions using getaddrinfo and gethostbyname were still
mistakingly being used/linked even if c-ares was selected as resolver
backend.

Test 161 updated accordingly

In commit c834213a we re-used some obsolete error codes, and here are
two defines that makes sure existing source codes that happen to use any
of these deprecated ones will still compile.

As usual, define CURL_NO_OLDIES to avoid getting these "precaution
defines".

Previously the code would create a dummy socket while resolving just to
have curl_multi_fdset() return something but the non-win32 version
doesn't do it this way and the creation and use of a socket that isn't
made with the common create-socket callback can be confusing to apps
using the multi_socket API etc.

This change removes the dummy socket and thus will cause
curl_multi_fdset() to return with maxfd == -1 more often.

With this change, curl compiles with the new OPENSSL_NO_SSL_INTERN
cflag. This flag might become the default in some distant future.

make 'pidfile' and 'logfile' options appear first on command line in order
to ensure that processing of other options which write to logfile do this
to intended file and not the default one.

Fixed a problem in POP3 and IMAP where a connection would fail when
CURLUSESSL_TRY was specified for a server that didn't support
SSL/TLS connections rather than continuing.

The STARTTLS response code in SMTP, POP3 and IMAP would return
CURLE_LOGIN_DENIED rather than CURLE_USE_SSL_FAILED when SSL/TLS
was not available on the server.

There's a new 'http-proxy' server for tests that runs on a separate port
and lets clients do HTTP CONNECT to other ports on the same host to
allow us to test HTTP "tunneling" properly.

Test cases now have a <proxy> section in <verify> to check that the
proxy protocol part matches correctly.

Test case 80, 83, 95, 275, 503 and 1078 have been converted. Test 1316
was added.

Unfortunately we have no test cases for this and I have no SSPI build or
server to verify this with. The change seems simple enough though.
