Marcelo Araujo 8951f05525 Rework CTL frontend & backend options to use nv(3), allow creating multiple 
ioctl frontend ports.

This revision introduces two changes to CTL:
- Changes the way options are passed to CTL_LUN_REQ and CTL_PORT_REQ ioctls.
  Removes ctl_be_arg structure and associated logic and replaces it with
  nv(3)-based logic for passing in and out arguments.
- Allows creating multiple ioctl frontend ports using either ctladm(8) or
  ctld(8).
  New frontend ports are represented by /dev/cam/ctl<pp>.<vp> nodes, eg /dev/cam/ctl5.3.
  Those device nodes respond only to CTL_IO ioctl.

New command-line options for ctladm:
# creates new ioctl frontend port with using free pp and vp=0
ctladm port -c
# creates new ioctl frontend port with pp=10 and vp=0
ctladm port -c -O pp=10
# creates new ioctl frontend port with pp=11 and vp=12
ctladm port -c -O pp=11 -O vp=12
# removes port with number 4 (it's a "targ_port" number, not pp number)
ctladm port -r -p 4

New syntax for ctl.conf:
target ... {
    port ioctl/<pp>
    ...
}

target ... {
    port ioctl/<pp>/<vp>
    ...

Note: Most of this work was made by jceel@, thank you.

* Ahh, getopt(3) is a pain.
*
* This is a gross hack. There really aren't many other good
* options (excuse the pun) for parsing options in a situation like
* this. getopt is kinda braindead, so you end up having to run
* through the options twice, and give each invocation of getopt
* the option string for the other invocation.
*
* You would think that you could just have two groups of options.
* The first group would get parsed by the first invocation of
* getopt, and the second group would get parsed by the second
* invocation of getopt. It doesn't quite work out that way. When
* the first invocation of getopt finishes, it leaves optind pointing
* to the argument _after_ the first argument in the second group.
* So when the second invocation of getopt comes around, it doesn't
* recognize the first argument it gets and then bails out.
*
* A nice alternative would be to have a flag for getopt that says
* "just keep parsing arguments even when you encounter an unknown
* argument", but there isn't one. So there's no real clean way to
* easily parse two sets of arguments without having one invocation
* of getopt know about the other.
*
* Without this hack, the first invocation of getopt would work as
* long as the generic arguments are first, but the second invocation
* (in the subfunction) would fail in one of two ways. In the case
* where you don't set optreset, it would fail because optind may be
* pointing to the argument after the one it should be pointing at.
* In the case where you do set optreset, and reset optind, it would
* fail because getopt would run into the first set of options, which
* it doesn't understand.
*
* All of this would "sort of" work if you could somehow figure out
* whether optind had been incremented one option too far. The
* mechanics of that, however, are more daunting than just giving
* both invocations all of the expect options for either invocation.
*
* Needless to say, I wouldn't mind if someone invented a better
* (non-GPL!) command line parsing interface than getopt. I
* wouldn't mind if someone added more knobs to getopt to make it
* work better. Who knows, I may talk myself into doing it someday,
* if the standards weenies let me. As it is, it just leads to
* hackery like this and causes people to avoid it in some cases.
