Previously fusefs would never recycle vnodes. After VOP_INACTIVE, they'd
linger around until unmount or the vnlru reclaimed them. This commit
essentially actives and inlines the old reclaim_revoked sysctl, and fixes
some issues dealing with the attribute cache and multiply linked files.

Any change to a directory's contents should cause its mtime and ctime to be
updated by the FUSE daemon. Clear its attribute cache so we'll get the new
attributs the next time that they're needed. This affects the following
VOPs: VOP_CREATE, VOP_LINK, VOP_MKDIR, VOP_MKNOD, VOP_REMOVE, VOP_RMDIR, and
VOP_SYMLINK

I got most of -o default_permissions working in r346088. This commit adds
sticky bit checks. One downside is that sometimes there will be an extra
FUSE_GETATTR call for the parent directory during unlink or rename. But in
actual use I think those attributes will almost always be cached.
