Konstantin Belousov 547831b6fd Rework the vnode cache recycling to meet free and unused vnodes ...

targets.  See the comment above wantfreevnodes variable for the
description of the algorithm.

The vfs.vlru_alloc_cache_src sysctl is removed.  New code frees
namecache sources as the last chance to satisfy the highest watermark,
instead of selecting the source vnodes randomly. This provides good
enough behaviour to keep vn_fullpath() working in most situations.
The filesystem layout with deep trees, where the removed knob was
required, is thus handled automatically.
