Konstantin Belousov 9f70117263 Eliminate adj_free field from vm_map_entry. 
Drop the adj_free field from vm_map_entry_t. Refine the max_free field
so that p->max_free is the size of the largest gap with one endpoint
in the subtree rooted at p. Change vm_map_findspace so that, first,
the address-based splay is restricted to tree nodes with large-enough
max_free value, to avoid searching for the right starting point in a
subtree where all the gaps are too small. Second, when the address
search leads to a tree search for the first large-enough gap, that gap
is the subject of a splay-search that brings the gap to the top of the
tree, so that an immediate insertion will take constant time.

Break up the splay code into separate components, one for searching
and breaking up the tree and another for reassembling it. Use these
components, and not splay itself, for linking and unlinking. Drop the
after-where parameter to link, as it is computed as a side-effect of
the splay search.
