[libunwind] libunwind v0.95 released

[David Mosberger]

OK, I just released v0.95 of libunwind.  You can get it at:

        ftp://ftp.hpl.hp.com/pub/linux-ia64/libunwind-0.95.tar.gz

Relative to v0.95, here are some of the main changes:

 - Fixed lots of bugs (multi-threaded apps should work a lot better,
   for example).

 - Greatly improve unwind performance on ia64 by avoiding expensive
   sigprocmask()/pthread_lock() operations (for this to work, a
   yet-to-be-released version of Hans Boehm's atomic_ops [1] package
   needs to be installed on the system, otherwise, you'll get the old
   & slow way).

 - Add a new dynamic unwind-info format called
   UNW_INFO_FORMAT_REMOTE_TABLE.  This format is identical to
   UNW_INFO_FORMAT_TABLE, except that the table is assumed to live in
   remote memory.

 - The interface of _Uia64_find_dyn_list() changed in a trivial
   manner.  I don't think this affects anyone other than gdb so far,
   but if this is causing you troubles, please let me know.

Thanks to everybody who has contributed to libunwind since the last
release.  Keep those patches coming!

Enjoy,
