* David Mosberger <davidm@hpl.hp.com> implemented the setcontext family
of functions for Linux/IA-64.
* The RPC code is now thread safe. Threads can now use the same service
of different services at the same time. Patch by Eric Norum
<eric.norum@usask.ca> with some help by Ulrich Drepper.

[26] ...done
[27] We need a second test suite with tests which cannot run during a normal

can test things like DNS (i.e., require network access),
user-interaction, networking in general, and probably many other things.

* Makefile (libthread_db-routines): Add td_symbol_list.
* Versions [libthread_db] (GLIBC_2.2.3): Add td_symbol_list.
* td_symbol_list.c: New file.
* thread_db.h: Add prototype for td_symbol_list.
* thread_dbP.h: Define symbol name indices.
Add prototype for td_lookup.
* td_ta_event_addr.c: Use td_lookup instead of directly using
ps_pglobal_lookup to find symbol address.
* td_ta_get_nthreads.c: Likewise.
* td_ta_new.c: Likewise.
