return -1. This causes filters to fail because we get a value for
child_pid we weren't expecting. Set SIGCHLD to SIG_DFL instead to clear
the reapchild setting when forking the child lpd.
otherwise generate an UVM trap or will access random memory. This is due to
the dereference of vp->v_specmountpoint that is really
vp->v_specinfo->si_mountpoint. The field v_specinfo is multiplexed with
other structs in the vun union in struct vnode like struct socket.
The patch adds a sanity check for accessing the specinfo fields by only
allowing VBLK nodes to be passed. In theory also VCHR could be valid since
its also a special node though mounting is only done on VBLK so be strict.
Ok'd by yamt.
lenght calculation phase instead of just growing the buffer like the older
patch did. I am leaving the bigger buffer too for now since it does not hurt.
md_view_labels() and a variable to mark its availability, so checking of
the available disklabels can be done before the root device is chosen.

This PR claims that MacOSX 10.1 cannot print postscript files to a NetBSD
lpd because the mac will tag the file with an "o" for postscript, which
we do not handle. Rather than simply mapping o -> f as was done in the
PR, or mapping o -> l as was done in FreeBSD, I have implemented full
support for the "o" option. If a postscript filter does not exist in the
printcap file however, it will default to "l" handling.
With this change, you can now specify a "pf" or postscript filter in your
printcap, and have it handle postscript files sent to it with "lpr -o".
The "o" format in lpd is specified in RFC1179 as being a valid format flag.

Add a workaround for VIA EHCI controllers which, under load, signal qTD
completion before they have performed writeback from the overlay qTD.
This condition would exhibit itself as a umass stall that never recovers.
