Include winapi/config.hpp as soon as possible; avoid including even
Boost.Config before it so that it doesn't set Windows API version
accidentally by including some third party header. In all source files,
include detail/config.hpp or detail/setup_config.hpp first thing.
Moved all WinAPI config macros to the Jamfile.v2 and removed
windows_version.hpp as it was no longer needed. Also enabled inclusion of
windows.h while compiling the library.
Removed auto-linking with psapi.lib and advapi32.lib as it was no longer
working after ecf3114. Added linking with advapi32.lib to Jamfile.v2.
