Peter Wemm 4e61198e8f Make the vnode opv vector construction fully dynamic. Previously we ... leaked memory on each unload and were limited to items referenced in the kernel copy of vnode_if.c. Now a kernel module is free to create it's own VOP_FOO() routines and the rest of the system will happily deal with it, including passthrough layers like union/umap/etc. Have VFS_SET() call a common vfs_modevent() handler rather than inline duplicating the common code all over the place. Have VNODEOP_SET() have the vnodeops removed at unload time (assuming a module) so that the vop_t ** vector is reclaimed. Slightly adjust the vop_t ** vectors so that calling slot 0 is a panic rather than a page fault. This could happen if VOP_something() was called without *any* handlers being present anywhere (including in vfs_default.c). slot 1 becomes the default vector for the vnodeop table.
