Corinna Vinschen 8d0a7701aa Cygwin: mmap: use extended memory API if available
So far Cygwin was jumping through hoops to restrict memory
allocation to specific regions.  With the advent of VirtualAlloc2
and MapViewOfFile3 (and it's NT counterpart NtMapViewOfSectionEx),
we can skip searching for free space in the specific regions
and just call these functions and let the OS do the job more
efficiently and less racy.

Use the new functions on W10 1803 and later in mmap.
