…dlerEx

windows.RegisterServiceCtrlHandlerEx context parameter is uintptr, so it
is unsafe to pass pointers in that parameter. Use theService global
variable in ctlHandler function instead.

GetAce obtains a pointer to an access control entry (ACE) in an
discretionary access control list (DACL), which controls access to
an object.

Adds the ACE_HEADER and ACCESS_ALLOWED_ACE structs.
Adds GetEntriesFromACL function which returns an array of ACEs from the
given ACL if no errors have been encountered.

NetBSD apparently doesn't allow remapping into used address space.
This means that the test that uses mremap to move a mmapped page
into a new address should first mmap (to reserve)
then munmap (to free) the destination.

OpenBSD apparently doesn't allow unmapping address space if part of the region is already unmapped.
This tweaks the test so that munmapping twice no longer happens.
