    kernel: Cleanup <sys/uio.h> issues.
    
     The iovec_free() inline very complicates this header inclusion.  The
     NULL check is not always seen from <sys/_null.h>.  Luckily only three
     kernel sources needs it: kern_subr.c, sys_generic.c and uipc_syscalls.c.
     Also just a single dev/drm source makes use of 'struct uio'.
     * Include <sys/uio.h> explicitly first in drm_fops.c to avoid kfree()
       macro override in drm compat layer.
     * Use <sys/_uio.h> where only enums and struct uio is needed, but ensure
       that userland will not include it for possible later <sys/user.h> use.
     * Stop using <sys/vnode.h> as shortcut for uiomove*() prototypes.  The
       uiomove*() family functions possibly transfer data across kernel/user
       space boundary.  This header presence explicitly mark sources as such.
     * Prefer to add <sys/uio.h> after <sys/systm.h>, but before <sys/proc.h>
       and definitely before <sys/malloc.h> (except for 3 mentioned sources).
       This will allow to remove <sys/malloc.h> from <sys/uio.h> later on.
     * Adjust <sys/user.h> to use component headers instead of <sys/uio.h>.
    
     While there, use opportunity for a minimal whitespace cleanup.
    
     No functional differences observed in compiler intermediates.
