Remove prototypes for functions that don't exist anymore (vm_map.h).
Remove a useless argument from vm_map_madvise's interface (vm_map.c,
vm_map.h, and vm_mmap.c).
Remove a redundant test in vm_uiomove (vm_map.c).
Make two changes to vm_object_coalesce:
1. Determine whether the new range of pages actually overlaps
the existing object's range of pages before calling vm_object_page_remove.
(Prior to this change almost 90% of the calls to vm_object_page_remove
were to remove pages that were beyond the end of the object.)
2. Free any swap space allocated to removed pages.
