Added libuv example multi-uv.c
test1509: verify proxy header response headers count

Modified sws to support and use custom CONNECT responses instead of the
previously naive hard-coded version. Made the HTTP test server able to
extract test case number from the host name in a CONNECT request by
finding the number after the last dot. It makes 'machine.moo.123' use
test case 123.

Adapted a larger amount of tests to the new <connect> style.

RELEASE-NOTES: add two references
multi-uv.c: remove unused variable
RELEASE-NOTES: Corrected typo
Merge remote-tracking branch 'bagder/master'
ftp_sendquote: use PPSENDF, not FTPSENDF

The last remaining code piece that still used FTPSENDF now uses PPSENDF.
In the problematic case, a PREQUOTE series was done on a re-used
connection when Curl_pp_init() hadn't been called so it had messed up
pointers. The init call is done properly from Curl_pp_sendf() so this
change fixes this particular crash.

SO_SNDBUF: don't set SNDBUF for win32 versions vista or later

The Microsoft knowledge-base article
http://support.microsoft.com/kb/823764 describes how to use SNDBUF to
overcome a performance shortcoming in winsock, but it doesn't apply to
Windows Vista and later versions. If the described SNDBUF magic is
applied when running on those more recent Windows versions, it seems to
instead have the reversed effect in many cases and thus make libcurl
perform less good on those systems.

This fix thus adds a run-time version-check that does the SNDBUF magic
conditionally depending if it is deemed necessary or not.
