Cygwin: mmap: allow remapping part of an existing anonymous mapping
Previously mmap with MAP_FIXED would fail with EINVAL on an attempt to
map an address range contained in the chunk of an existing mapping.
With this commit, mmap will succeed, provided the mappings are
anonymous, the MAP_SHARED/MAP_PRIVATE flags agree, and MAP_NORESERVE
is not set for either mapping.
