6bbfc962d3 (David Lee, <david.lee@teracruz.com>) 
This patch fixes a semaphore leak within valgrind. If your application
dynamically allocates/releases semaphores, you will very quickly run out.
Also, as a nice side effect, it implements sem_destroy properly.

(me)
Protect sem_getvalue with a lock/unlock of the semaphore's mutex,
like the other routines do.

2c11c2d1fc Add post-FV suppressions needed to make it tolerably quiet on SuSE 9.

fails on SuSE 9.

391451cb5f Statically allocate a page in the client address space for trampoline

22fd0f99dc For whatever reason, ld-2.3.2.so (ld-linux.so.2) seems to have its own

79c85b65bf Use the redir machinery to forcibly remap stpcpy in libc.so.6 to our 
own version in mac_replace_strmem.c.  We have to do this the hard way
because overenthusiastic PLT bypassing in glibc means the usual
symbol-override stuff doesn't work.  IOW, for the usual reason that we
have to use the redir machinery at all.

This makes many programs run much more quietly on SuSE 9.

918c3a7b7e This jumbo-checkin is the Full Virtualization checkin. This eliminates 
Valgrind's dependency on the dynamic linker for getting started, and
instead takes things into its own hands.

This checkin doesn't add much in the way of new functionality, but it
is the basis for all future work on Valgrind.  It allows us much more
flexibility in implementation, and well as increasing the reliability
of Valgrind by protecting it more from its clients.

This patch requires some changes to tools to update them to the changes
in the tool API, but they are straightforward.  See the posting "Heads
up: Full Virtualization" on valgrind-developers for a more complete
description of this change and its effects on you.

e77d4b8d7e When merging multiple symbols with the same address, rather than always 
choosing the longest symbol, choose the longest ignoring any of the libc
junk prefixes like __libc_, __, __GI_*, etc.  This makes the symbol
presented to the user in messages and used in *.supp files more consistent
and comprehensible.
