- Defined IBV by default. The cost is only a few if statement
  checks at ckpt time.
- Added EXTERN C interface to the WRAPPER_EXECUTION_{DISABLE,ENABLE}_CKPT 
  macros.
fixing bug from r1075.
- example-db.c : Delay sendData/query ops for one process :
   exposes a bug in barrier; useful for testing as well as illustration
- dmtcp_backtrace.py : Fixed to work with Python 2.4
- jassert.cpp : Fix bug related to modification in rev. 1069
- Minor polishing
Introducing _real_pthread_mutex_XXX() functions outside RECORD_REPLAY
- Fixing a bug caused by bad interaction of dlopen/dlsym/dlerror
  wrappers and calloc.
- Putting RestoreTarget in dmtcp namespace.
- Fixes for RECORD_REPLAY which broke in rev 1079
- Made dmtcp_module_disable_ckpt() and dmtcp_module_enable_ckpt() thread-safe.
- Fixed logic for registering and querying.
Backwards process migration: take 1

- This fix restore the process even if the file sizes on the restart
  machine are smaller than the original one.
- It also handles the case when libc is not longer visible in
  /proc/self/maps after restart.
- Not that setup_clone_entry() has been disabled in mtcp.c. This may
  cause future problems. We should go back and revisit the design.
Quick fix for MPICH2 MPD process manager.
Bugfixes and minor changes in MTCP/DMTCP interaction.
- backtrace.py, dmtcpmodule.cpp : Bug fixes for stack trace on --enable-debug
   dmtcpmodule.cpp fixes bug in dmtcp_get_uniquepid_str(), dmtcp_get_tmpdir()
- dmtcp_checkpoint.cpp, execwrappers.cpp : comments on how to improve
    handling of setuid/setgid processes in a future revision
- exec_util.cpp : Check if copying setgid process failed: affects
    binaries like /usr/libexec/utempter/utempter, which can have
    execute but not read permission in some distros
- minor polishing
- Added a client-server test to 'make check'
- Augmented tidy targets for Makefile.in, test/Makefile.in
- Bash will sometimes keep open LDAP sockets, and DMTCP can't restore those.
  Now, LDAP sockets are detected at connect time, declared TCP_EXTERNAL_CONNECT,
  and at restart time, they are replaced by dead sockets.  A program using
  LDAP sockets should be prepared to reconnect when external sockets die.
- Use automake version 1.11 from home build machine.  (We had a mixture
  of automake 1.11.1 and 1.11.)
- Fix for LDAP connections.  DMTCP should now correctly convert them
   to dead sockets on restart.
This code overwrites the malloc hooks before calling dlsym. This fixes the
following bug: while testing DMTCP + OpenMPI, a segfault was generated really
early on (no checkpoint/restart was involved). The cause of the segfault was
dlsym, which called calloc. OpenMPI overwrote the hooks for malloc, which were
calling dlsym again.
- Makefile.in and mtcp/Makefile revised to make ./configure --enable-m32
   work again (but it still has a bug remaining)
- Makefile.in revised to provide more information in display-build-env target
- minor polishing
- Minor fix for debian packaging.
