Implement POSIX_MADV_WILLNEED/POSIX_MADV_DONTNEED for newer OSes
* autoload.cc (DiscardVirtualMemory): Import.
(PrefetchVirtualMemory): Import.
* mmap.cc (posix_madvise): Actually implement POSIX_MADV_WILLNEED
utilizing PrefetchVirtualMemory and POSIX_MADV_DONTNEED utilizing
DiscardVirtualMemory on systems supporting them.
* wincap.h (wincaps::has_broken_prefetchvm): New element.
* wincap.cc: Implement above element throughout.
(wincapc::init): Make sure has_broken_prefetchvm is only true on
W10 under WOW64.
* include/cygwin/version.h (CYGWIN_VERSION_DLL_MAJOR): Bump to 2003.
(CYGWIN_VERSION_API_MINOR): Reset to 0.
* new-features.xml (ov-new2.3): New section, document posix_madvise
POSIX_MADV_WILLNEED/POSIX_MADV_DONTNEED change.
