- Don't waste a potentially huge amount of time calling describe_addr
on addresses in errors we aren't going to show.
- If an invalid address is just below %ESP, say that it might be due
to a gcc bug. Increase the window in which this is allowed to
1024 bytes below %ESP.

right up front, in the VG_(record_*_error) functions. This is an
attempt to avoid excessive performance problems with programs which
have excessive numbers of errors.

when running multithreaded. Can still cause crashes (assertion failures)
when GDB exits. I think it that's due to my use of libc's system()
call; should roll my own.

by the scheduler, not by generated code. So pass in the relevant
ThreadState*; don't get it from VG_(get_current_tid)().

Fall back to a compromise position, which makes my mutex implementation
initialiser- and structure-compatible with LinuxThreads, and ditto the
upcoming condition var implementation. In particular this means that
((ThreadId)0) is an invalid thread ID, so vg_threads[0] is never used,
and vg_threads[1] specially denotes the "main" thread.
Remove the scheme of having a linked list of threads waiting on
each mutex. It is too difficult to get the right semantics for
when a signal is delivered to a thread blocked in pthread_mutex_lock().
Instead, use the old scheme of each thread stating with its .waited_on_mx
field, which mutex it is waiting for. This makes pthread_mutex_unlock()
less efficient, but at least it all works.

Various enhancements:
* Make the error message system more thread-aware.
* Fix stupid bug in do_pthread_create causing incorrect initial
%ESP values sometimes.
* Fix various other minor things needed to make opera work.
Performance of threaded apps is pretty terrible. This needs
looking into.

"Conditional jump or move depends on uninitialised value(s)", since
that will be more meaningful to most programmers. Also change the
suppression-kind to Cond in .supp files. The old Value0 descriptor
means the same and is still accepted. Suggested by Joe Buck
<Joe.Buck@synopsys.com>.

Allow suppressions with only a single level of backtrace, for suppressing
against libraries compiled with -fomit-frame-pointer.
