simple interface to extracting and setting cookies in libcurl's internal
"cookie jar". See the new cookie_interface.c example code.

variable declarations.

passed to the app using the header callback

and merge when new names are added

trailer is then sent to the normal header callback/stream.

seems the Windows (MSVC) libc time functions may return data one hour off if
TZ is not set and automatic DST adjustment is enabled. This made
curl_getdate() return wrong value, and it also concerned internal cookie
expirations etc.

fix the CONNECT authentication code with multi-pass auth methods (such as
NTLM) as it didn't previously properly ignore response-bodies - in fact it
stopped reading after all response headers had been received. This could
lead to libcurl sending the next request and reading the body from the first
request as response to the second request. (I also renamed the function,
which wasn't strictly necessary but...)

The best fix would to once and for all make the CONNECT code use the
ordinary request sending/receiving code, treating it as any ordinary request
instead of the special-purpose function we have now. It should make it
better for multi-interface too. And possibly lead to less code...

Added test case 265 for this. It doesn't work as a _really_ good test case
since the test proxy is too stupid, but the test case helps when running the
debugger to verify.

freeaddrinfo to the trace output

(and besides, we should be using the same %-code for all pointers)

defining, since the system headers themselves redefine getaddrinfo

with CURLOPT_PROXY can use a http:// prefix and user + password. The user
and password fields are now also URL decoded properly.

Test case 264 added to verify.

It now properly handles code that uses curl_free() (since not all versions of
curl have it), and also fixes a few problems when detecting libcurl on MinGW,
and a linker problem on OSX Panther.
