kernel/apple_gmux: Fix compilation when VGA_SWITCHEROO is in the config.
We would get a redefinition warning/error, because opt_drm.h has
VGA_SWITCHEROO defined to 1 in this case, which is not the same as
merely defining it. To be on the safe side, define to 1 here, too,
and also add an #ifndef and a comment.

kernel - Reduce excessive inode hash table allocations
* Reduce excessive inode hash table allocations in various filesystems
(primarily ufs). Introduce vfs_inodehashsize() to calculate a reasonable
hash table size instead of using 'maxvnodes'.
* The new formula is to generally use maxvnodes / 2 (2 x stacking for the
chained hash table). When maxvnodes is large we use maxvnodes / 4, and
if maxvnodes is very large (> 1M vnodes) we use maxvnodes / 8. This
significantly reduces the amount of kernel memory used when mounting
ufs, ext2fs, hpfs, isofs, msdosfs, nfs, ntfs, and smbfs filesystems.
