Version 1.2 of OpenDDS.

New to this version are the following changes:

- Implemented the WaitSet, GuardCondition, and StatusCondition interfaces
  from the OMG DDS specification.

- Implemented DomainParticipant::get_current_time() from formal/07-01-01.

- Added the ability for using multiple repositories to provide redundant
  service metadata management.

  The ability to federate repositories and redirect applications to
  attach to a new repository in the event a repository fails or becomes
  unreachable.  This is an experimental feature.

- Removed requirement for repository domain specification files.

  Repositories will manage DomainParticipants and their contained
  Entities in any domain without requiring the domain to be prespecified
  in a configuration file.  This removes the '-d' command line argument
  from the repositories as well.

- Internal service Entity identifiers have been expanded to 128 bits.

  These internal identifiers were previously 32 bits.  The 128 format
  follows the format of OMG Specification formal/08-04-09 (The Real-time
  Publish-Subscribe Wire Protocol DDS Interoperability Wire Protocol
  Specification, Version 2.0) GUID_t unique identifier type.

  OpenDDS places the identifier value for the DataWriter Entity of a
  publication on the wire to identify the source of data samples.  This
  means that this version of OpenDDS WILL NOT INTEROPERATE with previous
  versions since the 128 values are not compatible with the previous 32
  bit values.

- Java Bindings for OpenDDS

  See $DDS_ROOT/java/README, $DDS_ROOT/java/INSTALL, $DDS_ROOT/java/FAQ

- dcps_ts.pl changes

  Modified this script to create a single idl, header, and source file
  no matter how many types are contained within the input idl file.  This
  allows the output file names to be based upon the input file name (instead
  of the types found in the idl file).  Users of prior OpenDDS versions can
  use the script $DDS_ROOT/bin/update_dcps.pl to assist with this transition.

  Added a command line argument to allow an output directory to be
  specified.  All output files will be placed into this directory if
  present.  They will continue to be placed in the current directory if
  this argument is not present.

- DCPSInfoRepo changes

  A new library has been introduced (libDCPSInfoRepoServ) which provides
  the neccessary hooks for running the DCPSInfoRepo within another process.
  For example usage, see: $DDS_ROOT/dds/InfoRepo/DCPSInfoRepo.cpp.

- Fixed bug in DCPSInfoRepo that did not re-evaluate the compatibility and
  associations when QoS change is made.

- Fixed bugs that affected connection establishment.

  Fixed DataWriterImpl to handle the case that remove_association is called
  before fully_associated is called.

  Fixed a race condition that connection delay deletion removes new assocaitions.

  Corrected fully association ack verification to fix issues when multiple
  associations of a datalink are added simultaneously.

- Added datalink_release_delay and removed keep_link configuration.

  The datalink_release_delay is the delay for datalink release after no
  associations. It defaults to 10 seconds. This is to fix disconnect
  problem happened when removing and adding association related to
  same datalink during short period.

  Removed keep_link which can be replaced with a big value of
  datalink_release_delay.

- Fixed a potential deadlock in reliable multicast transport.
