From ffee0868ef1341cfb7622821431cb73c52590962 Mon Sep 17 00:00:00 2001
From: Sebastien Braun
Date: Sun, 3 Oct 2010 16:14:44 +0200
Subject: Assorted Multicast Fixes:

- Upgrade bundled OpenPGM to SVN r1135
- Timing fixes: Make all rate-limited and timer-pending operation wait
  for at least 1ms to avoid busy-waiting
- No distinction between sending and receiving sockets when setting
  up socket options (Receivers need to be able to send anyway when
  using PGMCC).
- Switch from fixed-rate transmission to using PGMCC for congestion
  control.
- Remove some obnoxious debugging outputs
- Some white space fixes
- Introduce a short waiting time before actually starting file transmission
  in order to allow enough SPM messages to be sent so that receivers
  can initialize properly.
- Fix MCASTFTANNOUNCE message to include full file name instead of basename.
- Fix generateMcastTransferID in order to gather more random IDs. PVSGUI
  may become confused if transfer IDs are reused.
- Properly dispose of clientFileReceiveDialog when multicast transfer is
  finished.
- Properly display transfer size in clientFileReceiveDialog
