History
Alan Cox fec296887f Refactor vm_map_find(), creating a separate function, vm_map_alignspace(), 
for finding aligned free space in the given map.  With this change, we
always return KERN_NO_SPACE when we fail to find free space.  Whereas,
previously, we might return KERN_INVALID_ADDRESS.  Also, with this change,
we explicitly check for address wrap, rather than relying upon the map's
min and max addresses to establish sentinel-like regions.

This refactoring was inspired by the problem that we addressed in r326098.
