np 2e36f0c10a Make the iSCSI parameter negotiation more flexible. 
Decouple the send and receive limits on the amount of data in a single
iSCSI PDU.  MaxRecvDataSegmentLength is declarative, not negotiated, and
is direction-specific so there is no reason for both ends to limit
themselves to the same min(initiator, target) value in both directions.

Allow iSCSI drivers to report their send, receive, first burst, and max
burst limits explicitly instead of using hardcoded values or trying to
derive all of them from the receive limit (which was the only limit
reported by the drivers prior to this change).

Display the send and receive limits separately in the userspace iSCSI
utilities.

/*
* 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.
*
