22fb174482 Corrected various comments. Removed commented out code. Added code for tracing thread context switches and danger set updating. Fixed memory leak. Danger set is now updated every time a new segment is created instead of only at every context switch, which fixes the bug that no data races were reported for the pth_barrier test program.

22b3fe2a3e DRD updates (Bart Van Assche):
- Updated copyright statement: replaced 2006-2007 by 2006-2008.
- Added copyright statement in the files where it was missing
(drd_track.h and drd_clientreq.c)
- Eliminated dependencies on core header files -- there are no more
#include "pub_core....h" directives in the exp-drd source code.
- Added semaphore support.
- Added barrier support.
- Added pthread_mutex_timedlock() support.
- Stack depth of stack traces printed by exp-drd can now be set via
--num-callers=...
- Added command-line option --trace-barrier=[yes|no].
- Added regression test for pthread_barrier() (matinv, a program that
performs matrix inversion).
- Added regression test sem_as_mutex, which tests whether race
detection works correctly when a semaphore is used to ensure mutual
exclusion of critical sections.
- Some of helgrind's regression tests are now used to test both
helgrind and exp-drd: tc17_sembar and tc18_semabuse.
- Cleaned up bitmap implementation code now that the const keyword has
been added to the declarations of the OSet functions.
- Cleaned up exp-drd/Makefile.am
- Updated exp-drd/TODO.txt

de4d2156cc DRD changes (Bart Van Assche)
* Add docs: exp-drd/docs/README.txt
* Added one drd suppression pattern, and cleaned up the suppression file.
* All regression tests now pass on x86_64 and i386, including sigalrm.
* Updated TODO.txt file.
* pth_create_chain test is now started with 100 threads instead of 10
  -- 10 was not enough.
* DRD no longer exits on PPC32 and PPC64 but just prints a warning
  message before it starts.
