... so that it adheres to the API documentation.

At some point recently we lost the default value for the easy handle's
connection cache, and this change puts it back to 5 - which is the
former default value and it is documented in the curl_easy_setopt.3 man
page.

The new read and write wrapper functions support reading from stdin
and writing to stdout/stderr on Windows by using the appropriate
Windows API functions and data types.

Count up numcookies in Curl_cookie_add() only when cookie is new one

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.

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.

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.

As of 25-mar-2013 wcsdup() _wcsdup() and _tcsdup() are only used in
WIN32 specific code, so tracking of these has not been extended for
other build targets. Without this fix, memory tracking system on
WIN32 builds, when using these functions, would provide misleading
results.

In order to properly extend this support for all targets curl.h
would have to define curl_wcsdup_callback prototype and consequently
wchar_t should be visible before that in curl.h.  IOW curl_wchar_t
defined in curlbuild.h and this pulling whatever system header is
required to get wchar_t definition.

Additionally a new curl_global_init_mem() function that also receives
user defined wcsdup() callback would be required.

Proxy servers tend to add their own headers at the beginning of
responses. The size of these headers was not taken into account by
CURLINFO_HEADER_SIZE before this change.
