Root the lib32 object tree under the overall object tree.

This enables a common root directory for all object files for a given tree,
which eases sharing a common MAKEOBJDIRPREFIX, and cleaning up of object trees.

In particular, one can simply (from the source directory) rm -rf /usr/obj$(pwd)
to destroy all object files for it.  Or to copy/sync files, etc.

Fix a kernel panic when unloading isp(4).

In the current implementation, the isp_kthread() threads never exit.

The target threads do have an exit mode from isp_attach(), but it is
not invoked from isp_detach().

Ensure isp_detach() notifies threads started for each channel, such
that they exit before their parent device softc detaches, and thus
before the module does.  Otherwise, a page fault panic occurs later in:

sysctl_kern_proc
  sysctl_out_proc
    kern_proc_out
      fill_kinfo_proc
        fill_kinfo_thread
          strlcpy(kp->ki_wmesg, td->td_wmesg, sizeof(kp->ki_wmesg));

For isp_kthread() (and isp(4) target threads), td->td_wmesg references
now-unmapped memory after the module has been unloaded.  These threads
are typically msleep()ing at the time of unload, but they could also
attempt to execute now-unmapped code segments.

Add laggproto broadcast, it allows sends frames to all ports of the lagg(4) group
and receives frames on any port of the lagg(4).

The lagg(4) interface is based on trunk(4) interface from OpenBSD.
The FreeBSD is the only system that has the FEC protocol, that is a simple alias
to loadbalance protocol and does not implement the ancient Cisco FEC standard.

From now on, we remove the fec protocol from the documentation and keep the FEC
code only for compatibility.

r258695 introduces a sanity check for makefs in order to verify that
the minimum image size specified is always less than the maximum
image size. If makefs(1) is invoked specifying minimum image size,
but not maximum one, the program exits with an error. Example:

# sudo -E makefs -M 538968064 -B be /home/davide/disk.img $DESTDIR
makefs: `/home/davide/tftproot/mips' minsize of 538968064 rounded up
to ffs bsize of 8192 exceeds maxsize 0.  Lower bsize, or round the
minimum and maximum sizes to bsize.

Assert then that minsize < maxsize iff maxsize is specified.
This change allows me to build MIPS images using makefs(1) and following
what specified in the wiki again.
