static libcurl using openssl as dll.

version of libcurl with different Windows versions. Current version of
libcurl imports SSPI functions from secur32.dll. However, under Windows NT
4.0 these functions are located in security.dll, under Windows 9x - in
secur32.dll and Windows 2000 and XP contains both these DLLs (security.dll

Renamed import lib to "libcurl_imp.lib".
Some cleanup and making it more readable.

Changes for removing libcurl.def file on Win32.
Added "CURL_EXTERN" to memdebug.h functions.
Cleaned up Makefile.vc6.
