Robert Watson a152f8a361 Change semantics of socket close and detach. Add a new protocol switch 
function, pru_close, to notify protocols that the file descriptor or
other consumer of a socket is closing the socket.  pru_abort is now a
notification of close also, and no longer detaches.  pru_detach is no
longer used to notify of close, and will be called during socket
tear-down by sofree() when all references to a socket evaporate after
an earlier call to abort or close the socket.  This means detach is now
an unconditional teardown of a socket, whereas previously sockets could
persist after detach of the protocol retained a reference.

This faciliates sharing mutexes between layers of the network stack as
the mutex is required during the checking and removal of references at
the head of sofree().  With this change, pru_detach can now assume that
the mutex will no longer be required by the socket layer after
completion, whereas before this was not necessarily true.

a note to committers about KAME tree
$FreeBSD$
KAME project


FreeBSD IPv6/IPsec tree is from KAMEproject (http://www.kame.net/).
To synchronize KAME tree and FreeBSD better today and in the future,
please understand the following:

- DO NOT MAKE COSTMETIC CHANGES.
  "Cosmetic changes" here includes tabify, untabify, removal of space at EOL,
  minor KNF items, and whatever adds more output lines on "diff freebsd kame".
  To make future synchronization easier. it is critical to preserve certain
  statements in the code.  Also, as KAME tree supports all 4 BSDs (Free, Open,
  Net, BSD/OS) in single shared tree, it is not always possible to backport
  FreeBSD changes into KAME tree.  So again, please do not make cosmetic
  changes.  Even if you think it a right thing, that will bite KAME guys badly
  during upgrade attempts, and prevent us from synchronizing two trees.
  (you don't usually make cosmetic changes against third-party code, do you?)

- REPORT CHANGES/BUGS TO KAME GUYS.
  It is not always possible for KAME guys to watch all the freebsd mailing
  list traffic, as the traffic is HUGE.  So if possible, please, inform
  kame guys of changes you made in IPv6/IPsec related portion.  Contact
  path would be snap-users@kame.net or KAME PR database on www.kame.net.
  (or to core@kame.net if it is necessary to make it confidential)

Thank you for your cooperation and have a happy IPv6 life!


Note: KAME-origin code is in the following locations.
The above notice applies to corresponding manpages too.
The list may not be complete.  If you see $KAME$ in the code, it is from
KAME distribution.  If you see some file that is IPv6/IPsec related, it is
highly possible that the file is from KAME distribution.
