[Valgrind-developers] New patches

[Jeremy F. <je...@go...>]

New patches of note:

21-hg-hashed-lockset
    HELGRIND: New implementation of LockSets. This changes the
lockset_table into a hash, and changes the representation of each
LockSet from a list into an array. This improves performance (mainly
because of the hash, but the arrays are more cache friendly too), and
simplifies the code.

22-mutex-destroy-unlock
    It seems that glibc assumes in its internal use of pthreads that
destroying a lock implicity unlocks it. This patch handles this case so
that lock ownership tracking is accurate.

    Also handles the case of the dyanmic linker wanting to do locking
before Valgrind has started up. vg_libpthread now implements toy
lock/unlock functions to keep it happy and leave the locks in a sensible
state. Implements some untested code to handle the case where a lock is
taken before Valgrind is running but released afterwards.

23-intercept-select-poll
    Do the intercept thing for select and poll.  At some point I should
sit down and do this systematically for all the functions that
vg_libpthread wants to define but normal libpthread doesn't.

24-sym-offset
    When looking up a symbol, also attach an offset. Also changes to
make sprintf reentrant.
