Doug Moore 52499d1739 Eliminate some uses of the prev and next fields of vm_map_entry_t. 
Since the only caller to vm_map_splay is vm_map_lookup_entry, move the
implementation of vm_map_splay into vm_map_lookup_helper, called by
vm_map_lookup_entry.

vm_map_lookup_entry returns the greatest entry less than or equal to a
given address, but in many cases the caller wants the least entry
greater than or equal to the address and uses the next pointer to get
to it. Provide an alternative interface to lookup,
vm_map_lookup_entry_ge, to provide the latter behavior, and let
callers use one or the other rather than having them use the next
pointer after a lookup miss to get what they really want.

In vm_map_growstack, the caller wants an entry that includes a given
address, and either the preceding or next entry depending on the value
of eflags in the first entry. Incorporate that behavior into
vm_map_lookup_helper, the function that implements all of these
lookups.

Eliminate some temporary variables used with vm_map_lookup_entry, but
inessential.
