This adds -Werror-implicit-function-declaration for GCC 2.95+ so that
these errors are visible at the point where they occur instead of only
at link time.
Implicit function declarations are illegal in C99 and C++ anyway, and
the same warning has been turned into an error for ICC in commit
3072c5b8.

- Change documented param type to char ** from incorrect long *.

--without-ssl is needed instead of --with-winssl.

... by moving the variables into the correct #ifdef block.

Closes #1397

When UNICODE is not defined, the Curl_convert_UTF8_to_tchar macro maps
directly to its argument. As it is declared as a pointer to const and
InitializeSecurityContext expects a pointer to non-const, both MSVC and MinGW
issue a warning about implicitly casting away the const. Fix this by declaring
the variables as pointers to non-const.

Closes #1388

This checks the new behavior of Curl_splaygetbest, so that the smallest
node not larger than the key is removed, and FIFO behavior is kept even
when there are multiple nodes with the same key.

Closes #1358

Multi handles repeatedly invert the queue of pending easy handles when
used with CURLMOPT_MAX_TOTAL_CONNECTIONS. This is caused by a multistep
process involving Curl_splaygetbest and violates the FIFO property of
the multi handle.
This patch fixes this issue by redefining the "best" node in the
context of timeouts as the "smallest not larger than now", and
implementing the necessary data structure modifications to do this
effectively, namely:
 - splay nodes with the same key are now stored in a doubly-linked
   circular list instead of a non-circular one to enable O(1)
   insertion to the tail of the list
 - Curl_splayinsert inserts nodes with the same key to the tail of
   the same list
 - in case of multiple nodes with the same key, the one on the head of
   the list gets selected

... by explicitly calling the ANSI versions of Windows API functions where
required.
